ПРЕДИСЛОВИЕ КО ВТОРОМУ ИЗДАНИЮ Настоящий учебник предназначен для студентов стоматологических факультетов медицинских вузов и составлен с учетом языковой базы, сформированной у студентов в процессе изучения английского языка в средней общеобразовательной школе. Целью учебника является формирование у студентов-стоматологов навыков чтения и перевода аутентичных медицинских текстов, пополнение словарного запаса специальной стоматологической лексикой, а также развитие навыков профессионально-ориентированной устной речи для более широкого включения в сферу общения на английском языке в области медицины и стоматологии. Учебник содержит тексты для практики перевода, ознакомительного, поискового и изучающего чтения, лексические, грамматические и коммуникативные упражнения, грамматические комментарии и справочные материалы, необходимые в учебном процессе, приложения и англо-русский стоматологический словарь. Учебник построен по тематическому принципу и состоит из десяти разделов (20 уроков), охватывающих основные направления профессиональной деятельности будущих стоматологов: основные системы органов человека (major organ systems), зубы, прорезывание зубов (human teeth, eruption of teeth), ротовая полость, зубные ткани (mouth cavity, dental tissues), организация здравоохранения и стоматологической помощи в России и Великобритании (health care in Russia and Great Britain), распространенные заболевания зубов и полости рта (diseases of the teeth and mouth cavity), профилактика стоматологических заболеваний, лечение и протезирование зубов (oral disease prevention, endodontics, dental prosthetics). Ввиду того что авторы придают большое значение работе над оригинальными текстами в процессе обучения языку, было сочтено необходимым построить учебный материал в двух планах, дополняющих друг друга, что и нашло свое отражение в структуре уроков, каждый из которых состоит из двух частей. Первая часть урока содержит оригинальный текст, и главный упор в ней делается на изучение, толкование перевода и передачу содержания текста, а также на расширение словарного запаса студентов и на анализ изучаемых лексических единиц (выявление многозначности, подбор синонимов, антонимов и т.д.) в целях развития навыков устной и письменной речи. Вторая часть урока представляет собой
дальнейшую разработку соответствующей темы и рассчитана на расширение запаса лексических единиц. Каждый раздел (unit) содержит 2-3 урока (lessons). В первой части урока основному тексту предшествует список труднопереводимых слов, словосочетаний и терминов при этом отбор лексических единиц обусловлен частотностью их употребления в речи. Тексты, на которых строится работа в первой части каждого урока, взяты из оригинальных источников, они даются без адаптации с частичным сокращением. По своему содержанию они связаны с текстами второй части урока. Система упражнений включает дотекстовые и послетекстовые лексические упражнения, грамматические упражнения на повторение ранее изученного материала и отработку новых тем, упражнения для развития навыков устной речи, что позволяет последовательно и качественно усвоить предложенный лексикограмматический материал и научиться применять полученные знания в практической работе с английским языком. В основу системы упражнений положены следующие методические принципы: упражнения даны в порядке нарастания сложности; устные упражнения чередуются с письменными. Представленный в конце учебника раздел Grammar Revision позволяет повторить и закрепить пройденный материал. Упражнения для развития навыков устной речи дают возможность научиться составлять сообщение на основе прочитанного текста, выражать свое мнение по поводу прочитанного, вести беседу в рамках изученной тематики. Оригинальные научно-популярные тексты, входящие в раздел Additional Reading Material, способствуют формированию самостоятельных высказываний по изучаемому разделу стоматологии и созданию условий для последовательной и целенаправленной работы по освоению навыков перевода и реферирования иноязычного текста по специальности. Учебник также включает ряд полезных приложений, в том числе англорусский стоматологический словарь, список терминов и словообразовательных элементов греко-латинского происхождения, используемых в медицине и стоматологии, которые трудно найти в других справочниках, а также списки предлогов, соединительных слов и сокращений, представляющих определенные трудности при переводе оригинальных текстов. При создании данного учебника использовались следующие источники. 1. Encyclopaedia Britanica, 2006.

Exercise 4. Read the text and translate it into Russian. AN INTRODUCTION TO DENTISTRY Dentistry is the branch of the healing arts and sciences devoted to maintaining the health of the teeth, gums, and other hard and soft tissues of the oral cavity and adjacent structures. A dentist is a scientist and clinician dedicated to the highest standards of health through prevention, diagnosis, and treatment of oral diseases and conditions. The notion of dentists as those who merely «fill the teeth» is completely outofdate. Today, dentists are highly qualified health professionals who provide a wide range of care that contributes enormously to the quality of their patients' day-today lives by preventing tooth decay, periodontal disease, malocclusion, and oralfacial anomalies. These and other oral disorders can cause significant pain, improper chewing or digestion, dry mouth, abnormal speech, and altered facial appearance. Dentists are also instrumental in early detection of oral cancer and systemic conditions of the body that manifest themselves in the mouth, and they are at the forefront of a range of new developments in cosmetic and aesthetic practices. There are many clinical fields in dentistry. General dentists use their oral diagnostic, preventive, surgical, and rehabilitative skills to restore damaged or missing tooth structures and treat diseases in the mouth and adjacent structures. Endodontists diagnose and treat diseases and injuries that are specific to the dental nerves and pulp (the matter inside the tooth). Oral pathologists are dental scientists who study and research the causes, processes, and effects of diseases of the mouth cavity.
Orthodontists treat problems related to irregular dental development, missing teeth, and other abnormalities. Pediatric dentists specialize in treating children from birth to adolescence. Periodontists diagnose and treat diseases of the gingival tissue and periodontium. Prosthodontists replace missing natural teeth with fixed or removable prosthetic appliances. Dentistry offers an array of professional opportunities from which individuals can choose to best suit their interests. VOCABULARY EXERCISES Exercise 1.

People like you who choose dentistry as a career open up a world of opportunities that exist for dentists now and make oral health one of the most exciting, challenging, and most rewarding professions. Dental schools are looking for individuals who are motivated, academically prepared, socially conscious, and knowledgeable about the profession. What can you say about yourself that will make you stand out? Why Dentistry? A STUDENT PROFILE OF RENEE ROLAND, UNIVERSITY OF BUFFALO SCHOOL OF DENTAL MEDICINE Why dentistry?There are no dentists in my family, and I had no experience with dentistry, but in high school I had a dream of becoming a doctor one day. I felt dentistry would be a good mix of science and interacting with patients, so it was always my intention during undergrad (last year at university) that I was going to pursue dentistry. I attended Canisius College and took a special course in biology. Canisius has a program with the University of Buffalo (UB) that allowed me to apply to dental school in my second university year. I did and was accepted. It was the best decision I ever made. What are you doing now? I'm finishing my fourth year of dental school and applying to orthodontic residency program. I went to dental school with the intention of practicing general dentistry, but you just don't know what is going to happen. I found I loved orthodontics and working with kids. I also did research this
summer in molecular biology. We were studying the expression of genes in bone cells. Where do you see yourself in five years? Hopefully, I will have finished my schooling. I want to remain in the New York area and become an associate in an orthodontic practice. I really enjoy treating patients. Questions: 1. How did you become interested in studying dentistry? (Explain how you discovered dentistry as a career possibility). 2. What have you done to demonstrate your interest in dentistry? (Have you observed or worked in dental offices. Have you talked to practising dentists?) 3. Do you have any special talents or skills for the profession? Exercise 3. Read the text below and give a short summary of it. PERSPECTIVES ON HEALTH CARE IN THE NEW MILLENIUM In the United States of America and in Canada, perspectives on health care have changed over the last 30 years. Today, the public sees itself as a consumer of health-care services and products. This means that when individuals seek advice or treatment, they often come well-informed about their health issues and needs. Today's patient expects to be treated as an intelligent, competent person by the doctor, nurse, and other health-care professionals. No longer is the patient a passive receiver of health care. The new patient comes with information, education, and an inquiring mind. Professionally, today's view of health care is concerned with health promotion and disease prevention. It is no longer disease-focused or cure-focused. Health care is concerned with quality of life. In this new perspective, it extends beyond health challenges and basic medical care to lifestyle adaptations to ensure optimal health.
Healthy living programs in schools, businesses, and community agencies are an example of health promotion initiatives. Healthcare professionals and government at all levels collaborate with communities and patients/health-care consumers not only to promote health but also to provide the best health care possible.

I passed all the entrance exams successfully last summer and now I am a student of Moscow State Medicine and Dentistry University. It's the leading dental school in Russia. Apart from the Dentistry faculty there are also general medicine, secondary dental education and some others. The number of its departments is enormous, about a hundred in all. And all that started from a modest dental school way back in 1932, can you imagine?
We study different subjects such as the history of medicine, Latin, foreign languages, Anatomy, Biology, Physics, etc. No sign of dentistry yet. These are socalled pre-clinical subjects. At the end of the third year, after we have studied some special subjects, we'll have our first practical training. Then we'll be allowed to diagnose and treat patients on our own, even if under the guidance of our teachers. I live in Hall, like many other students who do not come from Moscow. It is rather far from the main building of our university and it takes me about an hour to get there. Fortunately, the bus stop is quite near. Our classes usually begin at 9 in the morning and end at around 3-4 p.m. Unlike at school, they last for 90 minutes. During a break we may have some rest or get a snack at the university's canteen. Apart from practical classes we also have a lecture or two every day. When back in Hall I have my dinner and sit down to prepare my homework. I'm often tired, but I like it just the same. Every day we learn a lot of interesting things in different fields of science. We often work in laboratories and have to read additional literature on some subjects in the library, too. Everybody understands that the knowledge we acquire at present will be necessary for our future work. When I happen to have some free time, which is very seldom, I listen to the music or watch TV. But now I'm working harder than ever. My first term here is coming to an end. There are two terms in the academic year and at the end of each one, in winter and in spring, we have examination sessions: several credit-tests and examinations. Those who get good marks get stipends. I hope I won't fail. Anyway, I'm going to do my best. Well, I must finish now. It's already past midnight and I've got to get some sleep or I won't be able to get up in the morn. I miss you very much. There'll be a lot to talk about when the examination session is over and I am back home again, for a holiday.

DENTAL EDUCATION ABROAD The goal of all dental school programs in the USA and Canada is to produce graduates who are competently educated in the basic biological and clinical sciences, and capable of providing quality dental care to all segments of the population. The traditional dental school program requires four academic years of study. Years One and Two. Students generally spend the major part of the first two years studying thebiological sciences to learn about the structure and function of the human body and its diseases. Students also receive instruction about basic sciences such as
human anatomy, physiology, biochemistry, microbiology and pharmacology, anddentally oriented biological sciences such as oral anatomy, oral pathology, and oral histology. They also learn the basic principles of oral diagnosis and treatment and begin mastery of dental treatment procedures through practice on models of the mouth and teeth. In many programs, students begin interacting with patients andprovide basic oral health care. Years Three and Four. The focus of the final two years of dental school generally concentrates on clinical study. Clinical training is designed to provide competence in the prevention, diagnosis, and treatment of oral diseases and disorders. Students apply basic principles and techniques involved in oral diagnosis, treatment planning, restorative dentistry, periodontics, oral surgery, orthodontics, pediatric dentistry, prosthodontics, endodontics, and other types of treatment through direct patient care. They learn to attend to chronically ill, disabled, special care, and geriatric patients and children. In addition, dental schools provide instruction inpractice management and in working effectively with allied dental personnel to provide dental care. The D.M.D. (Doctor of Dental Medicine) and the D.D.S. (Doctor of Dental Surgery) are equivalent degrees that are awarded to dental students upon completion of the same types of programs. Basic dental training in the United Kingdom consists of a full-time course leading to a Bachelor's degree. The degree course lasts for five years and includes an academic education supporting clinical practice of the care of patients. Graduates from UK dental schools must undertake a further year of vocational training (hands-on contact with patients), after registering with the General Dental Council (GDC), before they can practice in the UK. Questions:
1. How long is the traditional dental training course in the USA, Canada and UK? 2. What do students learn during the first two years at American dental schools? 3. What do the final two years of instruction focus on? 4. What degrees are awarded to graduates of American and Canadian dental schools? 5. What does the basic dental training in the UK involve? 6. How long does the degree course last? 7. What does it include? 8. What degree is awarded to British graduates upon completion of dental training? 9. What is necessary for a UK graduate to start practice in his/her own country? Exercise 3. Read and translate the text below using a dictionary. Be ready to say what you think of introducing the Bologna principles in Russia. RUSSIA AND THE BOLOGNA PROCESS Russia joined the Bologna Process in 2003 and is in the process of actually transforming its higher education system to make it compatible with Bologna principles. In particular, Russia has essentially moved to the two-tier, bachelor'smaster's or four-plus-two year system. The actual transformation is yet to happen, but all the legal foundations are in place. Universities that want to build internationally competitive, and internationally compatible, undergraduate and masters programs have all the necessary tools. The switch makes real sense. The Bologna Process, which started in 1999, is now a union of about 50 countries, including most European states, as they try to
establish a unified higher education area, capable of competing with North America. The «Bologna ideology» means it will be normal to find a job after a bachelor's degree rather than go on to study for a master's. The Bologna Process gives Russian universities an instrument for bilateral student exchanges and therefore wakes them up to the realities of the European educational system. It provides Russian universities with opportunities to create new programs both broad undergraduate programs and specialized master's programs. Exercise 4. Revise the material of the lesson and get ready to speak on one of the following topics making out a plan for it first. 1. My University. 2. My Working Day. 3. Dental Education in Russia and Abroad.

Exercise 3. Translate the following word combinations before reading the text. a remarkably complex and efficient machine, digestive food, vital internal organs, much lighter and more flexible, to be held together by a cementlike substance, to transport oxygen, it runs up and down, at the bottom, by contracting in response to nerve signals Exercise 4. Read and translate the following text into Russian. MUSCULOSKELETAL SYSTEM The human body is a remarkably complex and efficient machine. It takes in and absorbs oxygen through the respiratory system. Then the oxygen-enriched blood is distributed through the cardiovascular system to all tissues. The digestive system converts digestible food to energy and disposes of the rest. The skeletal-muscular system gives form to the body, and covering almost the entire mass is the skin, the largest organ of the body. The science of the structure of this complicated «machine» is called anatomy. One of the major systems is the skeletal-muscular system. The body is supported and given shape by this structure, consisting of more than 200 bones and the muscles and tendons which are connected to them. They are strong but can bend at their joints. They also serve as a shield, protecting the vital internal organs from injury. Bones are as strong as steel but much lighter and more flexible. They are composed of minerals, organic matter, and water, held together by a cementlike substance called collagen, and are filled with red and yellow bone marrow. The red marrow produces the red blood cells used throughout the body to transport oxygen, while the yellow marrow consists primarily of fat cells. A tough membrane called the periosteum covers most of the bone surface and allows bones to be nourished by blood.
A major bone structure in the body is the vertebral (spinal) column. It runs up and down the back and protects the spinal cord, where many of the major nerves are located. It is composed of bony vertebrae which are held together by ligaments of connective tissue and separated from each other by spinal discs. At the top of the vertebral column is the skull, which surrounds and protects the brain. The bony structure of the head and face is called the skull. It consists of 22 bones. The main parts are the cranium and the facial skeleton with the movable lower jaw bone (mandible) which enables man to talk and eat. The main bones of the face are the mandible, two upper jaw bones, two malar, two nasal, two lacrimal, two palate bones. All of these bones except the mandible are closely knit together. Attached to the vertebral column below the neck are the 12 pairs of ribs, comprising the rib cage. At the bottom is the sacrum, which connects the vertebral column to the pelvis. Bones are united by joints and held together by ligaments. Muscles are special fibrous tissues found throughout the body. They control movement and many organic functions by contracting in response to nerve signals. Skeletal muscles are called voluntary because they can be consciously controlled. They are attached to bones by tough fibrous tissues called tendons. Other muscles, such as the stomach muscles and the heart, are involuntary and are operated automatically by the central nervous system. Healthy muscles are said to have good muscle tone. Not all muscles are healthy, however, for various ailments may affect them. An inflammation of a tendon (tendonitis), of the protective sac at a joint (bursitis), or of a muscle itself (myositis) may occur. When a muscle becomes fatigued, it sometimes contracts violently and painfully. This condition is known as cramping. Too much strenuous activity may produce a strain. VOCABULARY EXERCISES

Read and translate into Russian the text «Skull» and do the exercise that follow it. SKULL Skull is the skeleton of the head and face, which is made up of 22 bones. It can be divided into the cranium, which encloses the brain, and the face including the lower jaw (mandible). The cranium consists of eight bones. The frontal, two parietals, occipital, and two temporals form the vault of the skull (calvaria) and are made up of two thin layers of compact bone separated by a layer of spongy bone. The remaining bones of the cranium - the sphenoid and ethmoid - form part of its base. The 14 bones that make up the face are the nasals, lacrimals, inferior nasal conchae, maxillae, zygomatics, and palatines (two of each), the vomer, and the mandible. All the bones of the skull except the mandible are connected to each other by immovable joints. The skull contains cavities for the eyes and nose and a large opening at its base (foramen magnum) through which the spinal cord passes. Find the English equivalents in the text to the words and word combinations below: скелет головы и лица, закрывать (защищать) мозг, состоять из, включая нижнюю челюсть, плотная (твердая) кость, губчатая (пористая) кость, за

Below are detailed diagrams of the skull bones (cranial and facial bones). Learn the names of the bones and skull bones anatomy through the skull bones diagrams. SKULL BONES. CRANIAL AND FACIAL BONES The human skull, scientifically known as the cranium, consists of 22 bones. The skull can be broken into two regions, the cranial section and the facial section. The cranial bones consist of the bones in the top of the skull while the facial bones consist of the bones that make up your face. The skulls primary functions are protection of the brain and support of the face. In the skull sinal cavities can be found. Although the function of these cavities is still not definitively known, it may be that the sinuses function is decreasing the weight of the skull while maintaining strength.

Read and translate into Russian the following text and answer the questions. CARDIOVASCULAR (CIRCULATORY) SYSTEM The cardiovascular system is sometimes also referred to as the circulatory system, although they are not quite the same thing. The term cardiovascular speaks to the two parts of the system: cardio meaning heart and vascularmeaning vessels. Anatomically, the major structures are the heart and blood vessels (arteries, veins, capillaries), but it is difficult to think of this system without including reference to the lungs (part of the respiratory system). The main function of the cardiovascular system is to distribute blood through blood vessels throughout the body. The main function of the heart is to pump the blood (to function as the engine of the cardiovascular system), beginning the process of circulation. The heart consists of myocardial tissue and is divided into four chambers: two atria and two ventricles. The left and right atria are the two upper chambers of the heart, the left and right ventricles the two lower chambers. Blood that is high in oxygen (oxygenated) flows into the left atrium from the lungs through the pul-
monary veins. The left atrium then contracts to pump a supply of blood to the left ventricle. The aorta is found in the left ventricle. It branches into a complex series of arteries that bring oxygenated blood to all of the organs of the body. When the blood reaches the capillaries, it delivers oxygen and in exchange picks up the waste product carbon dioxide to carry away through veins back to the heart. This blood in the veins empties first into the vena cava (the main vein in the human body), which then carries it to the right side of the heart. Next, this blood is pumped through the pulmonary artery to the lungs where it exchanges the carbon dioxide waste for a new supply of oxygen. The cycle then repeats. This cycle is powered by the contraction of the heart, which is caused by electrical impulses within the heart. The contraction of the heart is known as the heartbeat. The circulatory system is a subsystem of the cardiovascular system. It concerns itself with blood and the function of blood, but it is difficult to think of the circulatory system without thinking about the lymphatic system. They are essential to each other. Lymph cells assist in cleansing the blood of dead cells and bacteria. Blood is the mode of transport for lymph, nutrients, hormones, electrolytes, gases (oxygen and carbon dioxide), water, and wastes to and from cells. The capillaries are the site of this exchange between the blood and the tissues that surround them. Blood also helps stabilize body temperature and the natural pH balance. In summary, the cardiovascular system is most often thought of in terms of the heart, blood vessels, and the lungs. The circulatory system is most often thought of as the blood vessels, blood, lymph, and the heart. Questions: 1. What is another name for the circulatory system? 2. What is the main function of the cardiovascular system? 3. What are the major structures of the cardiovascular system?
4. What does the heart consist of? 5. What is the main function of the heart? 6. What is a heartbeat? 7. What is the function of the circulatory system? 8. What is blood? 9. What are capillaries?

Muscles comprise the second part of the system. They are responsible for most body movements. There are three main types of muscle - skeletal, smooth, and cardiac. Skeletal muscles are sometimes called striated muscles because of their striped appearance when seen under the microscope. They attach to bones of
the skeleton and are under voluntary control. This allows us to engage in physical activities such as walking, running, smiling, winking, and grasping. Skeletal muscles also allow us to manipulate things like holding a pencil or buttoning a shirt. Smooth muscles comprise the walls of organs such as the liver, spleen, and kidneys. They are responsible for the transport of nutrients and other materials through the body. Smooth muscles are not under voluntary control. We cannot make them work. Cardiac muscle is also involuntary.

Man's skeleton was formed more than million years ago. The skeleton is a tower of bones knit together by joints so that man can run, jump and bend. 206 bones protect the vital organs from injuries. The skeleton performs functions of support, movement and protection. The supporting function consists in supporting all the organs and giving the body a definite form and position. The skeleton, together with the muscles, constitute the motive apparatus. The human skeleton may be divided into the skeleton of the trunk, upper extremities, lower extremities and the skull. The bony part of the head is called the cranium or skull. The skull has a cavity which contains the brain. The bones of the skull form the mouth and nasal cavities. In the mouth cavity there are accessory organs of the digestive system. Exercise 4. Mark each statement below T (true) or F (false). Correct the statements that are false. 1.

Read and translate the following texts into Russian. NERVOUS SYSTEM The neurological system is commonly referred to as the nervous system. It directs all body systems and cells and is responsible for all thought, emotion, sensation, and movement. The nervous system consists of two major subsystems: the central nervous system and the peripheral nervous system. The brain is the center of both. The central nervous system is most often referred to as the CNS. It consists of the brain, brain stem, and spinal cord. The spinal cord and brain stem function as
communication pathways between the brain and the peripheral nervous system. The peripheral nervous system can be divided into several subdivisions. All the organs of the nervous system are composed of neurons, or nerve cells. Neurons contain a cell nucleus and dendrites and axons. Dendrites receive impulses from the sensory organs, such as the eyes and ears, and from other neurons and transmit them to the central nervous system. The central nervous system (either the brain or spinal cord) responds to this sensory input, sending impulses through the axons out to the body organs. The gap between sensory, intermediate, and motor nerves is referred to as a synapse. The human brain is essential to our ability to function in life. The capacity of the human brain is what sets us apart from other living things. Biological, psychological, emotional, creative, spiritual, and social functioning all arise from the brain. The «mind» is the cognitive capacity of the brain to think, problem solve, reflect, create, imagine, remember, and act in social, moral, and ethical ways. The brain is divided into two hemispheres and four lobes. The two hemispheres of the brain are most commonly identified simply by their location of left or right. The four lobes are the frontal, occipital, temporal, and parietal. The temporal lobes are responsible for memory, perception, and recognition of auditory stimuli. The ability to receive and understand speech is located within the left temporal lobe. The right temporal lobe concerns itself with memory for sounds and shapes. The parietal lobe is situated just under the bony skull cap. GASTROINTESTINAL SYSTEM The digestive system, which extends from the mouth to the anus, is responsible for receiving food, breaking it down into nutrients (a process called digestion), absorbing the nutrients into the bloodstream, and eliminating the undigestible parts of food from the body. The digestive tract consists of the mouth, throat, esophagus, stomach, small intestine, large intestine, rectum, and anus. The digestive system also includes organs that lie outside the digestive tract: the pancreas, the liver, and the gallbladder. The gastrointestinal system, often abbreviated as the GI system, is also known as the digestive system. The terms are completely interchangeable. They refer to a system designed to ingest and transport food so that digestion can occur. The system's main function is to provide the body with healthy nutrients and provide
means to expel waste materials and toxins. This occurs through a series of processes: ingestion, digestion, metabolism, absorption, and elimination. The alimentary canal forms the core of the system. A 28-foot long tract, it begins at the lips and proceeds through to the anus. It is composed of eight organs: the mouth, pharynx, esophagus, stomach, small intestine (and all associated glands), the large intestines (colon), rectum, and the anal canal and anus. When an object or fluid is placed in the mouth, the first process, ingestion, begins. Ingestion means taking a fluid, material, or substance into the body and swallowing it. Chewing (mastication) breaks larger pieces of solid materials into smaller pieces. Digestion also begins in the mouth when enzymes released by the salivary glands begin to break down sugars and other carbohydrates. The ingested material then passes the pharynx and enters the esophagus. Next, it travels downward through the alimentary canal to the stomach. The stomach begins to process its contents within the first 20 minutes of receiving food, fluid, and any other matter/substance. That material is broken down, metabolized, and formed into new substances, which are then passed along to the small intestine. Accessory organs such as the liver and pancreas are located adjacent to (near to) the GI system. They supply enzymes and hormones that further facilitate digestion and metabolism of the ingested material. It generally takes up to 6 hours for digestion to occur. During this process, solid products of digestion are transported into the small intestine. By the end of a 6-12 hour period, most of the ingested, digested material should have passed into the colon (large intestine). In summary, the main functions of the GI tract are ingestion, digestion, metabolism, absorption, and defecation. RESPIRATORY SYSTEM The respiratory system begins with the nose and mouth and continues through airways to the lungs. The lungs, the largest parts of the respiratory system, look like large pink sponges that almost fill the chest. The left lung is a little smaller than the right lung. Each lung is divided into sections (lobes): three in the right lung and two in the left. The ability of the lung to accommodate a sufficient intake of air is known as pulmonary capacity. Air enters the respiratory system through the nose and mouth and passes down the throat (pharynx) and through the voice box (larynx). The largest airway is the windpipe (trachea), which branches into two smaller airways (bronchi) to supply the two lungs. The bronchi themselves divide many
times before evolving into smaller airways (bronchioles). The airways look like an upside-down tree, which is why this part of the respiratory system is often called the bronchial tree. At the end of each bronchiole are dozens of bubble-shaped, air-filled cavities (alveoli) that resemble bunches of grapes. Each lung contains millions of alveoli, and each alveolus is surrounded by a dense network of capillaries. The pleura is a slippery membrane that helps the lungs move smoothly during each breath. It covers the lungs and comes back around to line the inside of the chest wall. The lungs and other organs in the chest are protected by a bony cage, which is formed by the breastbone (sternum), ribs, and spine. The intercostal muscles, which lie between the ribs, help move the rib cage and thus assist in breathing. The most important muscle used for breathing is the diaphragm, a bell-shaped sheet of muscle that separates the lungs from the abdomen. When the diaphragm contracts, it increases the size of the chest cavity and thus expands the lungs. The respiratory system has its own capacity to protect itself from toxins, viruses, bacteria, and other disease-causing agents. This is accomplished through the system's ability to secrete mucous. It is the system's most significant protective mechanism. Phlegm, on the other hand, is a sticky secretion of mucous that originates only in the lungs. VOCABULARY EXERCISES Exercise 1.

Exercise 4. Answer the questions to the text «Nervous System*. 1. What is the medical term for the nervous system? 2. According to the text, what directs all body systems and cells? 3. What does CNS stand for?
4. How many major subsystems are in the nervous system? 5. How are messages relayed from the brain to the body? 6. What's another word for neuron? 7. What is the most important function of the brain? 8. Where is the ability to understand speech located? Exercise 5. Read and translate into Russian the text «Pain and Headaches* and do an exercise that follows it. PAIN AND HEADACHES Pain, pain reception, and response are key elements of the neurological system. Pain is perceived by specialized nerve cells called pain receptors. The message is then relayed to the brain where a decision is made regarding the appropriate response. For example, in response to burning a finger, we may move our finger instantaneously out and away from the flame. However, not all pain occurs externally. Indeed, headaches are the most commonly known form of internal pain experienced. Headaches are often the result of stress, but they can also be triggered by external stimuli such as injury to the head, sudden exposure to bright lights, many hours under fluorescent lighting, certain foods and smells, and a myriad of other causes. People describe their headache signs and symptoms with the following descriptors: dizziness, spinning, pounding, hammering, mild, excruciating, and dull. They can usually locate the pain, as well. Headaches are usually of short duration. When suffering from a headache, people often appear cranky, impatient, and irritable. The condition brings with it a decrease in frustration tolerance, or the decreased capacity to tolerate frustration. One type of headache is a migraine. Migraines are severe and can be quite disabling. They are caused by a constriction of the blood vessels in the occipital area and down into the neck. This decrease in blood flow is experienced as throbbing pain usually felt at first on only one side of the head. Other symptoms include heightened sensitivity and intolerance to light and sound. During a migraine headache, frustration intolerance can be significantly increased. The sufferer may be irritable and unapproachable. It is important for the health-care professional to remember that the migraine sufferer is focused on his or her internal pain. They should not take the client's brusque or unfriendly attitude as personal in any way.
While migraines may need medical and pharmacological intervention, headaches in general do not. Over-the-counter analgesics, changes in one's day or in one's lifestyle to decrease tension, relaxation techniques, balanced nutrition, rest, and exercise can all positively affect resolution of the headache. Pain scales are the method of diagnosing the severity or degree of pain. Think about and answer the following questions: 1. Does all pain occur externally? 2. What is a migraine? 3. What is the difference between a headache and a migraine? 4. What is a pain scale? 5. What is frustration intolerance? Exercise 6.

Read the text «Lung cancer and Demographics* and translate it into Russian without a dictionary. Summarise it. LUNG CANCER AND DEMOGRAPHICS Lung cancer is a pathological disease of abnormal cell growth in the tissues of the lungs. In the Western world, men and women are being diagnosed with this horrific disease at equal rates. While the vast majority of cases of lung cancer are related to cigarette smoking, other causes are air pollution, exposure to asbestos or radon, and exposure to cigarette smoke. Early diagnosis and detection are essential if lives are to be saved. The proper medical terminology for cancer is carcinoma. Small-cell carcinoma is the most frequent type of lung cancer diagnosed. Cancer cells are assessed to determine if they are malignant or benign. A diagnosis of lung cancer is not a death sentence. Progress in treating the disease with surgery, chemotherapy, and radiation have saved and prolonged lives. As yet, however there is no guaranteed cure. Exercise 3.

Cardiovascular (circulatory) system - the system that carries blood to various parts of the body. It consists of the heart, blood vessels, and lymphatic system.
Digestive system - all the organs and glands involved in the ingestion and digestion of food, from the mouth to the anus. Endocrine system - the ductless glands that produce internal secretions and secrete these directly into the blood or lymph and circulate it to all body parts. These glands include the thyroid, parathyroid, adrenal cortex, adrenal medulla, anterior pituitary, posterior pituitary, testes, and ovaries. Integumentary system - the skin (the largest organ in the body) and its associated structures, including hair, nails, and sweat and sebaceous glands. Nervous system - a system of nerve cells including the brain, cranial nerves, spinal cord, spinal nerves, autonomic ganglia, and other nerves that handle the functions of reception of and response to stimuli. The nervous system regulates and coordinates bodily activities and enables the body to adjust to external and internal changes. Reproductive system - the system that enables human beings to have offspring. The male reproductive (genital) organs are mostly external and include the penis, the scrotum, and two testicles (testes) contained in the scrotum. The female sex organs are internal and include the vagina (with its opening covered by folds of skin called the vulva), the uterus, fallopian tubes, and ovaries. Respiratory system - the system that brings oxygen into the body and removes carbon dioxide. This process, called breathing, involves two acts: inspiration and expiration. The organs of this system are the nose, tonsils, pharynx, bronchi, pleura, and lungs. Musculoskeletal system - the system that protects and supports the internal organs and also helps the body move. The skeleton has 206 named bones including the skull, vertebral column, ribs, and the bones of the legs, hips, and shoulders. Surrounding the bones and soft organs of the body are more than 650 muscles. Urinary system - the system that removes urea and other waste materials from the body in a liquid calledurine. These waste materials come from the cells, go into the bloodstream, and then travel through the kidneys, ureters, bladder, urethra, and out of the body. Exercise 5. Mark each statement below T (true) or F (false). Correct the statements that are false. 1. Lung cancer is the most commonly diagnosed form of cancer. 2. Smoking increases a person's risk of getting lung cancer in 20 times.
3. A known risk factor for cancer is smoking marijuana. 4. If a doctor suspects lung cancer, the first diagnostic step is to have an X-ray made. 5. Bronchi are part of the skeleton. 6.

Read and translate the following text into Russian. STRUCTURE AND FUNCTIONS OF TEETH Adult humans typically have 32 teeth - 16 in the upper and 16 in the lower jaw. Teeth on the right side of each jaw are usually identical to the teeth on the left side. Humans have four types of teeth, each with a specific size, shape and function. Adult humans have eight incisors, located at the front of the mouth - four in the upper and four in the lower jaw. Incisors have a sharp edge that is used to cut food. Next to incisors are canines (cuspids), named so for their resemblance to the pointing fangs of dogs. The upper canines are sometimes called eyeteeth. There are two canines in each jaw, and their primary role is to tear and shred food. Next to canines are bicuspids, or premolars, flat teeth with pronounced cusps that grind and mash food. There are four bicuspids in each jaw. After bicuspids come molars with most vigorous chewing function. There are three sets of molars in each jaw referred to as the first, second and third molars. The third molars are often called wisdom teeth. They developed thousands of years ago when human diets consisted of mostly raw and unprocessed food that required extra chewing and grinding power. Today wisdom teeth are not needed for chewing. So, the functions of the teeth are obvious: to chew food and mix it with saliva, to aid speech, and to maintain the position of the jaws. The teeth are part of the digestive system. Each tooth is divided into a crown above the level of the gum, a neck, surrounded by the gum, and a root or roots embedded in the jaw. The crowns are chisel-shaped in incisor teeth, peg-shaped in canine teeth, have two tubercles in premolar teeth and several tubercles in molar teeth. The crown of each tooth is covered with dental enamel, the hardest substance of the body. The roots are encased in cement, not quite as hard. Inside enamel and cement is somewhat softer bony substance called dentin, which is the bulk of the tooth. Dentin surrounds the pulp chamber, where nerves and
Internal Tooth Anatomy 1 - tooth enamel 2 - dentin 3 - dental pulp 4 - cementum 5 - gums 6 - periodontal ligament 7 - alveolar bone blood vessels of the tooth are located. Blood vessels and nerves enter the tooth through a foramen at the tip of each root. The pulp of the tooth is one of the most sensitive structures of the body. The nerves and blood vessels run up or down through narrow channels, called root canals. Covering the roots of the tooth is the periodontal membrane, which holds the tooth in its socket in the jaw and takes up some of the shock of chewing.
PARTS OF A TOOTH External Tooth Anatomy CROWN is the visible part of a tooth, above the gums. ROOT is the part of a tooth under the gums and inside the alveolar bone. NECK is the area between the tooth crown and the root. VOCABULARY EXERCISES Exercise 1.

Read and translate the following text into Russian. ERUPTION OF TEETH
Humans develop two sets of teeth during their lives. The first set of teeth are deciduous teeth, 20 small teeth also known as baby teeth or milk teeth. Both baby and permanent teeth grow out of tooth buds that were laid down under gums fairly early in embryonic life (before birth). Baby's «first tooth» usually erupts above the gum line when he is about 6 months of age. The first deciduous tooth to erupt is one of the incisors. An infant usually has his full set of 20 deciduous teeth by the time he is 2 or 2И years old. Deciduous teeth influence the shape of the mouth and face. When baby teeth are lost too early the permanent teeth underlying them may erupt in an unnatural position and form a crowded or otherwise irregular dental arch. Furthermore, the child needs a good set of deciduous teeth to chew his food properly and to preserve a proper bite (occlusion) between the upper and lower jaws. Many children suffer from some degree of malocclusion (faulty bite). So, primary teeth are very important as they help permanent teeth to erupt in their normal positions. When a primary tooth is ready to fall out, its root begins to dissolve. This root has completely dissolved by the time the permanent tooth below it is ready to erupt. Children start losing baby teeth at about 6 years of age. The first adult teeth to erupt are permanent molars that come through at the back of the mouth, right after last milk molars. These four grinding teeth are extremely important for correct development of an adult dentition. They are called the «keystone of a dental arch» and will carry the main burden of chewing for many years. The eruption of permanent teeth starts around the age of 6. From then until the child becomes 12 years old all primary teeth loosen and fall out while permanent teeth come through in their place. Permanent teeth replace baby teeth in the mouth at the rate of about 4 a year for 6 or 7 years. The last teeth to erupt are «wisdom teeth» or third molars, which are usually delayed until late teens or early twenties. These teeth often come in crooked or «impacted» against second molars and may have to be extracted. A full set of adult or permanent teeth numbers 32: 8 on each side above and below, namely: 2 incisors, 1 canine, 2 premolars and 3 molars. TOOTH MORPHOLOGY OF PRIMARY TEETH The primary teeth are 20 in number, ten in each jaw: •8 incisors, •4 canines,
•8 primary molars. Deciduous teeth of the primary dentition are smaller than teeth of the same type in the permanent dentition, but they generally resemble them in the form.
TOOTH MORPHOLOGY OF ADULT TEETH

Read and translate the following text into Russian. THE MOUTH CAVITY
The oral (mouth) cavity is an oval-shaped cavity situated at the beginning of the alimentary canal. The oral cavity and oropharynx are spaces defined by both hard and soft tissue structures. The shape of theses two spaces changes with normal physiologic function of the surrounding structures during speech, swallowing and respiration. Functionally, the oral cavity and oropharynx are the pathway that food takes, their boundaries are the muscles that move the food. Although primarily a space through which food and air travel, several structures are found in this space including the upper and lower dentition, the tongue, salivary glands, mucosal glands, mucosal tissue covering the hard palate and alveolar ridges invested by the gum. The oral cavity is continuous with the pharyngeal cavity, a more complex and somewhat irregular space. The mouth cavity is bounded anteriorly by the lips, laterally by the cheeks, superiorly by the hard palate and inferiorly by mucosa covering the superior surface of the tongue. The secretions of the parotid, submaxillary and sublingual glands are poured into the mouth cavity and in it food is subjected to the processes of mastication and insalivation previous to deglutition. The teeth are the prime organs of mastication, implanted in the alveolar cavities. A tooth is composed of four distinct structures: 1) pulp occupying the chamber in the crown; 2) dentine which constitutes the bulk of the organ;
3) enamel which forms the protection of the crown; 4) cementum which covers the root. The teeth of the first dentition are termed deciduous or temporary teeth. The temporary teeth are replaced by a permanent set. The anatomical divisions of the tooth are: 1) the crown or exposed part situated above the gum; 2) the root occupying the alveolar cavity of the socket; 3) the neck which is between the crown and the root. The temporary teeth are twenty in number, ten in each jaw, namely: four incisors, two canines and four molars. The permanent teeth are thirty two in number, sixteen to each jaw, namely: incisors - four, canines - two, premolars - four, molars - six. The third or last molar is called the wisdom tooth. Wisdom teeth (one at every side of the jaw) are not a different type of teeth. They erupt between the age of 17 and 21. Wisdom teeth need special care. Sometimes they do not erupt properly and they often cause dental problems because of the difficulty to clean them well enough. The incisors or cutting teeth occupy the anterior central part of each maxillary arch. They have rather flat surfaces, a straight sharp horizontal edge for cutting and biting food and one long, single, conical root. The function of this class of teeth is to cut the food. The canine teeth are situated next to incisors, two to each jaw. They are larger and stronger than incisors. They are characterized by large conical crowns which project beyond the level of other teeth and one single root, larger than all other human teeth types. These teeth are for tearing food. Premolars, four to each jaw, are next to canine teeth. They have flat upper surfaces and one or two roots. Their crowns have two pyramidal eminences or cusps. They are used for chewing food. Molars occupy the posterior part of the alveolar arch and are six on each jaw. Molars are situated at the back of the mouth cavity. They have large flat upper surfaces and two to four roots. Molars are the largest permanent teeth used for chewing and grinding (molar is the Latin for «mill»). Third molars are known as wisdom teeth. Answer the questions to the text:
1. Where is the mouth cavity situated? 2. What sets of teeth do you know? 3. How many deciduous teeth are there on each jaw? 4. How many permanent teeth are there? 5. When does the first permanent tooth appear? 6. What place do wisdom teeth occupy on each jaw? 7. How can you characterize incisor teeth? 8. What place do incisor teeth occupy on each jaw? 9.

Exercise 5. Read and translate the text without a dictionary. The mouth is a part of the digestive system. There are the teeth, tongue, and salivary glands in the mouth. The cavity of the mouth is divided into two portions: the vestibule and the cavity proper. The vestibule of the mouth is a space bounded by the lips and cheeks. The lips and cheeks contain the mimic muscles. The oral cavity proper is bounded by the hard and soft palates. The hard palate separates the oral cavity from the nasal cavity. The mucous membrane covers the lips, and cheeks to the alveolar processes of the jaws. In the mouth the food is ground by the teeth and mixed with water, mucus and other secretions of the salivary glands. Saliva has a direct influence on the teeth and provides an optimal level of metabolic activity in the body. It consists of 99.5 percent water and 0.5 percent total solids. Its chief constituents are water, inorganic salts, mucin, serum albumen, globulin and ptyalin. Saliva dissolves some of the solid substances so that they are brought in contact with taste buds which stimulate appetite. Moistening food with saliva enables to facilitate swallowing. There are many salivary glands in the mouth. Three principal pairs are recognized: sublingual, submaxillary, and parotids. The salivary glands regulate the water supply of the body.

Read and translate the text and be ready to answer the questions given below. HUMAN TEETH The human teeth are made up of four tissues: enamel, dentine, cementum and pulp. Enamel is white, compact and very hard substance. It is the hardest of all the tissues of the human body. Enamel covers the exposed parts of a softer underlying dentine. Its function is to protect the teeth against wear and friction. Dentine or ivory is the tissue below the tooth enamel. It is the chief substance or tissue of the teeth composing the bulk and characteristic form of a tooth. It
surrounds the tooth pulp and is covered by enamel on the exposed part of the tooth and by cementum on the part implanted in the jaws. Dentine resembles a bone but is harder and denser. It supports the tooth enamel and absorbs the pressure of eating. Dental pulp is a soft connective tissue occupying the pulp chamber and most of tooth canals. It is found in the soft center of the tooth. Dental pulp is the remain of the formative organ which has given rise to dentine. The pulp of a tooth is composed of a number of branched fibrous network which contains nerves, blood and lymph vessels that nourish the tooth. The most superficial of these cells are arranged in the young tooth and known as odontoblasts, for they are active in the formation of dentine. Dental pulp is one of the most sensitive structures of the body and the most inner structure of a tooth. Cementum is the part of the tooth anatomy that covers dentine beyond the border of enamel, overlapping it slightly at the gingival line and forming, the surface of the root. Cementum closely resembles an ordinary bone. It begins at the neck as a very thin layer and is continued increasing in amount towards the apex which is formed entirely during life. Cementum is relatively small in amount in children but it increases during life. Cementum is as hard as bone but not as hard as the tooth enamel. Its function is to furnish the attachment to the bone of the jaw with little elastic fibers that fasten the tooth to the bone. The internal tooth structure is common in all types of teeth, but the external parts of tooth morphology (shape of tooth crown, number and shape of roots) differ significantly between tooth types. The human teeth are supported on the alveolar and supporting bones, the periodontal membrane and gingiva. The alveolar processes of the maxillary bones grow up around the roots of the teeth so that the roots fit into the holes in the bone and fasten the teeth. Periodontium is the supporting structure of a tooth. It is a complex of soft and hard tissues that surround the tooth, keep it in place, feed and protect it. Periodontal tissue provides through its tactile sensory mechanisms the protection against swallowing of hard, sharp and potentially dangerous materials. It also takes part in the formation of the bone of alveolar walls and of cementum. Gingiva is the part of mucosa which surrounds the cervical portion of a tooth. The width of gingiva tends to increase with age. VOCABULARY EXERCISES

Try to learn them. Read and translate the text and be ready to answer the questions given below. i.e. = id est (lat.) = that is - то есть, т.е. masticatory - жевательный palatal - нёбный pharynx - глотка to be located - быть расположенным to comprise (Lat.) - составлять, включать в себя to develop - развиваться to grow (grew, grown) - расти, увеличиваться в размере to include - включать to line - выстилать to observe - наблюдать to separate - разделять to support - поддерживать, служить опорой undergo - подвергать (ся) PERIODONTIUM AND ORAL MUCOSA The periodontium (peri - «around», odontos - «tooth») comprises the following tissues: gingiva, periodontal ligament, root cementum and the alveolar bone. Three of the periodontal tissues, the cementum, periodontal ligament and the alveolar bone are formed by cells which are contained in the dental follicle of a developing tooth. The fourth tissue component of the periodontium, i. e. gingiva, is not developed from a dental follicle. The gingiva is, however, a tooth-related structure which grows in height with the erupting tooth. The main function of periodontium is to attach the tooth to the bone tissue of the jaws and to maintain the integrity of the surface of masticatory mucosa of the oral cavity. The periodontium, also called «the attachment apparatus» or «the
supporting tissues of the teeth» establishes a developmental, biological and functional unit which undergoes certain changes which age. The oral mucosa (mucous membrane) is continuous with the skin of the lips and mucosa of the soft palate and pharynx. It consists of (1) masticatory mucosa which includes the gingiva and the covering of the hard palate, (2) specialized mucosa which covers the dorsum of the tongue and (3) the remaining part, called the lining mucosa. Gingiva is that part of masticatory mucosa which covers the alveolar process and surrounds the cervical portion of the teeth. Two parts of gingiva can be differentiated: free gingiva and attached gingiva. The free gingiva is oral pink and comprises gingival tissue at the vestibular and lingual/palatal aspect of the teeth. The attached gingiva is often of firm texture. This type of mucosa is firmly attached to the alveolar bone and cementum by connective tissue fibers. The width of the gingiva tends to increase with increasing age. It was found that the gingiva in 40-50 years olds was significantly wider than that in 20-30 year olds. Answer the questions to the text: 1. What does the word «periodontium» mean? 2. What tissues does periodontium comprise? 3. Are all the periodontal tissues formed by cells contained in the dental follicle? 4. Is gingiva related to the teeth? 5. What is the main function of periodontium? 6.

Exercise 4. Read and translate into Russian the following text. THE STRUCTURE OF THE MAXILLA The bones of the face consisting of the mandible and the superior maxillary bones form much of the anterior portion of the face. The superior maxillary bones are closely knit together except the mandible which is movable. The superior maxillary bones, being knit together on the median line of the face, are two in number and of a very irregular form. They occupy the anterior upper part of the face and consist of a body and processes. There are 4 processes which extend out from the body of the maxillae,
namely the frontal process, the zygomatic process the alveolar process and the palatine process. The alveolar processes of the right and left maxillae form an arch-like shape of bone that surrounds the roots of the maxillary dental arch of teeth. The roots of the teeth are embedded in individual alveoli (tooth sockets). The shape of each alveolus naturally corresponds closely with the shape of the roots of the tooth it surrounds. Being the largest bones of the face except the mandible, the maxillary bones enter into the formation of three cavities, namely: the orbit, the mouth and the nares. The body is the central part of the bone. The body is shaped like a foursided hollow pyramid with the base oriented vertically next to the nasal cavity. Its apex extends laterally into part of the cheek bone (or zygomatic bone). The body exhibits four surfaces, namely: the external or facial, the posterior or zygomatic, the superior or orbital and the internal or palatine. The facial surface is directed forwards and vertically, and the lower border is more protruded than the upper one. This surface presents a depression just above the canine and the first bicuspid teeth. It is called the canine fossa. Above the canine fossa, there is the infraorbital foramen for the nerve of the same name. The entrance to the alveolar canals, where the nerves to the maxillary teeth enter the maxilla, are very small foramina located posteriorly and superior to the third molar. The zygomatic surface is situated posteriorly forming the anterior boundary of the zygomatic fossa. Between it and the facial surface there is a well-developed ridge extending from the molar region to the base of the zygomatic process. The posterior surface has a bulging called tuberosity. It is connected with the palate and bounds the antrum behind. Being perforated by three or four small holes the posterior surface transmits nerves and blood vessels to the molar teeth. The orbital surface of the maxillae forms the greater part of the floor of the orbit, where an infraorbital fissure is located. VOCABULARY EXERCISES Exercise 1.

Exercise 3. Read and translate the text into Russian and be ready to answer some questions. THE STRUCTURE OF THE MANDIBLE The mandible lies below the anterior part of the cranium and is the skeleton of the lower part of the face. It has the body and a pair of flat, broad rami which stand up from the posterior part of the body. Each ramus is surmounted by two processes: the anterior is named the coronoid process, and the posterior is the condyloid one. The condyloid process has an articular part called the neck.
The right and left halves of the body of the mandible are united together in the medial plane in front. Their junction is called the symphysis menti. The halves of the mandible are joined together by fibrous tissue at birth, but they are fused together into one bone during the second year. Each half of the body of the mandible has an outer and an inner surface and an upper and a lower border. The surfaces slope so that the lower border makes a wider arch than the upper border. The upper part is known to be called the alveolar part because it is occupied by a row of alveoli, those are the sockets for the teeth. On each side the sockets for the two incisors, the canine and two premolars are single but for the three molars they are double, for each mandibular molar has two roots: anterior and posterior. The lower border is known to be the base of the mandible. The outer surface is slightly convex, but has a depression alongside the symphysis below the incisor teeth. The mental foramen is seen on the outer surface of the mandible. The inner surface is convex and concave at different parts. There is a shallow depression called the submandibular fossa. The mandibular foramen leads into a canal which runs in the substance of the bone and carries the vessels and nerves for the teeth. The mandible is the only bone of the face which has movement. The temporomandibular joint is known to make a wide range of mandibular motion. This joint consists of two joints on either side of the mandible, which articulate with temporal bones on either side of the head. The mandible serves as the attachment of the elevator muscles which consist of the masseter, temporal and internal pterygoid muscles. 1. What is the mandible? 2. What parts does the mandible consist of? 3. What part is called the alveolar one? 4. What bone of the face has movement? VOCABULARY EXERCISES Exercise 1.

Read and translate the following text into Russian. DENTISTRY TODAY Dentistry is the branch of medicine concerned with diagnosing, preventing, and treating diseases and abnormalities of the teeth and gums. Tooth decay and gum diseases are a health problem made worse by the kinds of food we eat. It is estimated that in the United States alone, 29 million people have no teeth of their own. One person in 3 over the age of 35 needs dentures (false teeth), while half the adults over 40 have some teeth missing because of gum disease. Until the middle of the 19th century, most dental operations were performed by travelling tooth drawers and barbers. Today the dentist, like the doctor, is a highlytrained person whose work is vital to the health of the community. The professional training of dentists lasts several years. For the first two years, most student dentists undergo general medical training. They study subjects such as anatomy (the structure of the body), physiology (how the body works), biochemistry (the chemical reactions in the body), and also special anatomy and physiology concerning the structure of the mouth and teeth, how the teeth grow, and how they become unhealthy or diseased. Gradually they specialize in dental subjects such as prosthodontics (the use and manufacture of false teeth), orthodontics (straightening teeth), conservation (fillings), and oral surgery (operations on the teeth, gumsjaws and other nearby parts).

THE COLLEGE OF DENTISTRY OF NEWYORK UNIVERSITY It is the third oldest and the largest private dental school in the United States. It is composed of clinics, laboratories, and other teaching facilities contained within several buildings. Since its foundation, New York University has been a private university, operating under a board of trustees. Being founded in 1865, the New York College of Dentistry became an integral part of New York University in 1925. A few years ago the College of Dentistry reached a decision to expand its previous three-year curriculum to a four-year curriculum. The curriculum is a synthesis of many areas of knowledge, including: biology, physics, biochemistry, medicine, surgery, biomechanics, aesthetics, manual skills and social sciences. In addition to providing the student with the biological and social basis for application of clinical skills, the educational programme focuses on prevention as a much desired goal in dental practice and research. Advances in the dental sciences and the increasing dental health needs of the public call for an understanding of general health problems and greater cooperation with other health professions. The educational goal is to educate and train clinically competent general practitioners, well-grounded in both basic and clinical sciences, fully prepared to adapt to changes in dental care needs and ready to keep up-to-date with the developing dental knowledge. During the first and second years, the course includes both the basic sciences and clinical sciences. Clinical practice during the first and second years begins with a series of lectures on the dental patient aimed at preparing the student for the duties and responsibilities of everyday practice. The student learns the importance and the role of the dentist as part of the health team. During the second, and continuing
into the third and fourth years, each student is assigned patients. Duties begin with examination of the patient and end only when the patient's dental health is restored to the best possible state. The students are responsible for treatment planning, making appointments and providing dental treatment. (Detailed information on the NYU College of Dentistry is given in Additional Material).

DENTAL CARIES AND PULPITIS Part 1 INTRODUCTION Diseases of the teeth develop primarily due to poor oral hygiene but the general state of health is also of some importance. Depending on the state of the whole body diseases of the teeth may run a more acute course and may quickly involve a number of teeth. Dental caries (tooth decay) and pulpitis are probably the most common of all diseases of the highly developed countries. All groups of population can suffer from tooth decay. The main causes of dental caries are poor oral hygiene, the character of nutrition (high consumption of sweets), the temperature of the food and physiological state of the human body. The disease begins with decalcification of the enamel and ends in destruction of the hard dental tissues. Carious lesions usually occur in those parts of the teeth that cannot be well cleaned by a toothbrush, the molars being most frequently affected. If caries is left untreated microorganisms can gain entrance into the pulp and cause its inflammation (pulpitis). During pulpitis teeth are sensitive to chemical, mechanical and thermal stimuli. Spontaneous severe pains are the most characteristic symptom of pulpitis. The pains may spread over thejaw, ear or
temple. They may be very severe and last for a long time. Pulpitis may result in gangrene of the pulp and its decomposition. The treatment of pulpitis must consist in mortification and removal of the pulp tissue and filling the tooth. Part 2 DENTAL CARIES Dental caries is a disease of the calcified tissues of the teeth caused by the action of micro-organisms on fermentable carbohydrates. It is characterized by demineralization of the mineral portion of enamel and dentine followed by disintegration of their organic material. As the disease approaches the pulp, it produces changes in the form of reactionary dentine and pulpitis (possibly giving pain), and may result in bacterial invasion and death of the pulp. The infected necrotic pulp then produces further changes in the periapical tissues. On the other hand, the disease can be arrested in its early stages since it is possible for remineralization to occur. In addition, progress of the disease to a clinical cavity is not inevitable, and can be completely prevented by relatively simple measures. Four factors are necessary to produce dental caries: • dental plaque; • a suitable carbohydrate (mainly sugar); • a susceptible tooth surface; • time. Unfortunately, caries presents symptomatically at a relatively late stage. The patient may feel a 'hole in a tooth' with the tongue, brown or black discoloration or cavities may be seen, or frank pain may be suffered. Caries, even in dentine, is not painful per se, but cavitation may occasionally cause a mild pain with sweet things or with heat or cold. Normally, the enamel and the necrotic dentine insulate the sensitive dentine and pulp from these stimuli. However, a much more common cause of pain, which may be intense, is pulpitis (the commonest 'toothache') which occurs late in the development of a carious lesion when caries is very close to the pulp or actually exposing it. There are four approaches to the management of caries:
• attempt to arrest the disease by preventive measures • remove and replace the carious tissues (operative dentistry) • a combination of these two approaches • extract the tooth. Early diagnosis of the carious lesion has become even more important since the realization that caries is not simply a process of demineralization, but an alternating process of destruction and repair. Saliva is an excellent remineralizing fluid and the balance can be tipped in favour of repair by modifying diet, careful use of fluoride, and removing plaque. Notes: disintegration - расщепление, распад inevitable - неизбежный, неминуемый susceptible - восприимчивый, чувствительный insulate - изолировать, ограждать to tip the balance - решить исход дела Part 3 PULPITIS Pulpitis may be painful or painless, but even the painless form may become painful in response to certain stimuli. For example, the tooth with painless pulpitis may become painful when percussed or may produce prolonged pain in response to electrical or thermal stimulation. Pulpitis may produce spontaneous pain, which may become severe. Pulpitis does not always develop from caries. It may result from trauma, internal resorption or both. Apparently, pulpitis from caries is reversible until the pulp is invaded by microorganisms. Its reversibility then depends on the number and virulence of the organisms and on therapy. Following invasion of the pulp by microorganisms, the prognosis for prolonged pulp viability is poor. Irreversible pulpitis continues to progress at varying rates through the pulp chamber and along the root canal. This progression leaves the contents of the pulp chamber necrotic or filled with pus and unable to respond to electrical or thermal stimuli. As the disease process passes through the apical foramina, it becomes apical periodontitis. Reversible pulpitis is treated by sedative dressings, while irreversible pulpitis is managed with endodontic therapy or extraction of the tooth.

Read and translate the following text and summarize it. THE DIAGNOSTIC PROCEDURE The diagnosis of caries requires good lighting and dry clean teeth. If heavy deposits of calculus or plaque are present, the mouth should be cleaned before attempting accurate diagnosis. Each quadrant of the mouth should be isolated in turn with cotton-wool rolls and dried with air or cotton-wool pledgets. Sharp eyes are necessary to look for the earliest signs of disease, and vision can be enhanced by the use of magnification. Magnifying loupes can be worn on a head band or attached to spectacles. Alternatively, special glasses with telescopes attached can be used, and have the advantage that they can be made to a specific focal length to suit the particular operator. Operative dentistry can only be made easier by the use of magnification. Traditionally a sharp probe was used to detect caries in enamel either by the rough feel of early cavitation on a smooth surface, or by the probe tips wedging between the softened sides of a fissure. This was known as a «sticky fissure*. However, a sharp probe can damage an incipient carious
lesion, actually causing cavitation in a lesion which might otherwise have been arrested. Further, by carrying microorganisms into the lesion a probe may facilitate the spread of the carious process. Therefore a probe should not be used in the diagnosis of enamel caries. Vocabulary to the text: quadrant - сектор to enhance - усиливать, увеличивать pledget - тампон cotton-wool roll - круглый ватный тампон magnification - увеличение magnifying loupe - увеличительное стекло, лупа accurate - точный radiograph - рентгеновский снимок incipient - начинающийся, начальный deposits of calculus - твердые зубные отложения alternatively - в качестве альтернативы probe - зонд to facilitate - способствовать, облегчать operative dentistry - одонтопрепарирование, терапевтическая стоматология Exercise 6.

Read and translate into Russian the following text. OPERATIVE AND RESTORATIVE DENTISTRY Tooth destruction can occur from dental caries (decay), attrition or abrasion, erosion and fracture. Dental caries, known more commonly as tooth decay, is the most common cause of tooth destruction. Caries (which literally means «rotten») results from the demineralization of mineralized tooth structures (that is the loss of minerals or inorganic content from enamel, dentin, and cementum).
Demineralization can be reversed if plaque is removed frequently enough through good oral hygiene measures, if sweets in the diet are limited, and minerals (especially calcium in healthy saliva and fluoride) are available for uptake (remineralization) into the porous demineralized tooth. This tug-ofwar between demineralization and remineralization is constant and is the basis for prevention methods that are applied and taught by dental professionals. Patient education and preventive treatment are important aspects of dental patient care. Prevention and treatment should be based on personalized risk-based assessment of each patient's caries history, which includes their history of fluoride use, their salivary flow rate, and the frequency of sugar uptake (especially snacks). Fluoride applied to teeth in appropriate concentrations has been shown to reduce dental caries incidence because it increases the tooth's resistance to breakdown by caries-forming acids. Therefore, caries prevention includes daily use of fluoridecontaining paste and fluoride-containing mouthwashes (either prescription or overthe-counter), as well as office applied fluorides that contain higher concentrations. Further, when saliva flow is reduced (from damage to salivary glands due to radiation therapy, or as a side effect to many medications), the teeth are more susceptible to tooth decay. Artificial saliva or sugarless chewing gum could be used to alleviate this problem. Finally, snacks provide the ingredients that, with certain bacteria found in dental plaque, form acids that contribute to demineralization. Therefore, frequent snacking must be curtailed. A number of reports have shown a worldwide decrease in the incidence of coronal caries, especially in children and adolescents, ranging from 10 to 60%. However, the number of adults older than 65 is expected to double by 2025, and people are keeping their teeth longer (53% of persons older than 65 still have at least 20 natural teeth). Further, the prevalence of root caries in the elderly is increasing, with one study reporting 75% of elderly women with clinically detectable root caries. Therefore, the restoration of damaged teeth (from caries and other reasons) will continue to be a part of practice of general dentistry for some time to come. Operative dentistry is the phase of dentistry involving the art and science of the diagnosis, treatment and prognosis of defects in teeth which do not require restorations that cover the entire tooth (full coverage). Restoring conservative tooth defects, such as those resulting from small carious lesions usually requires placement of intracoronal restorations whose preparations
are cut within the tooth and, iflocated occlusally, are narrower buccolingually than the distance between the cusps. As tooth destruction increases in size, extracoronal restorations may be a more appropriate restoration of choice. These larger extracoronal restorations surround and cover all or part of the exposed tooth, and include crowns (also known by many as «caps») or onlays (which have an intracoronal component but also include coverage of cusp tips). Treatment with extracoronal and intracoronal restorations should result in the restoration of proper tooth form, function and esthetics while maintaining the physiological integrity of the teeth in harmonious relationship with the adjacent hard and soft tissues, all of which enhances the general health and welfare of the patient. Restorative dentistry is the phase of clinical dentistry that includes not only the prevention and treatment of defects of individual teeth, but also the replacement of teeth that were lost or never formed. Lost teeth can be replaced using a fixed partial denture (also known as a bridge), a removable partial denture, an implant (surgical insertion or placement of artificial root over which a crown may be constructed), or complete dentures (also known as false teeth). Thus, restorative dentistry involves the restoration of lost tooth structure and/or lost teeth with the ultimate goal of reestablishing a healthy, functioning, and comfortable dentition.

THE DECAY PROCESS Tooth decay is an ongoing process that begins with plaque, a soft, transparent, sticky layer of harmful bacteria that constantly forms in the mouth. Certain bacteria in plaque use the sugar and starches in the food you eat to produce acids. The sticky plaque holds these acids on the teeth where they can destroy tooth enamel. Each time acid is produced, it attacks the tooth enamel for about 20 minutes. Plaque is most harmful when the bacteria have had time - about 25 hours - to organize into colonies. After repeated acid attacks, and if plaque is not removed daily, the enamel eventually breaks down and decays. Once that happens, the decay progresses inward to the centre of the tooth. If left untreated, the decay reaches the pulp of the tooth and an abscess forms at the root end, causing pain. At this stage, the tooth will need endodontic (root canal) treatment. Without treatment, the tooth must be extracted. Here are some warning signs of dental decay: - a tooth that is sensitive to heat, cold or sweet; - pain when chewing; - swelling or drainage at/or below the gumline; - a brown spot on a tooth; - a persistent pain in the mouth or sinus area. If you suspect that you have tooth decay, make a dental appointment without any delay. SPEECH EXERCISES Exercise 1. Answer the following questions to the text «Dental Caries and Pulpitis*.

Modern science tells us that caries originates under the combined effect of microorganisms and sugar. Bacteria absorb on the surface of the teeth due to the acid that occurs in saliva. Every bite of food containing sugar gives the bacteria energy allowing them to multiply and start producing acids. The result is the formation of cavities. The initial lesion of dental caries clinically is a white spot which may become stained brown. Adults of all ages can suffer from tooth decay. Two of three cavities in people older than 50 involve decay around fillings. Another type of tooth decay common in older people is root caries. Root caries generally occurs in adults who suffer from periodontal disease, when the roots are exposed. As the root surface is softer than the enamel the decay occurs more easily. A balanced diet that provides a sufficient amount of proteins, carbohydrates, fats, vitamins, minerals and water is important for both dental and general health. Other methods of dental caries control are: brushing teeth, fluoridation of water and early restoration of carious lesions.

The text reads about... According to the text... The main methods of caries control are enumerated... Exercise 8. Read and translate the text and classify dental caries according to pit and fissure versus smooth surface and describe the pattern of spread of each within enamel and dentin. CLASSIFICATION OF CARIOUS LESIONS
There are two broad classifications of tooth decay based on the anatomy of the tooth surface involved: pit and fissure, and smooth surface. The pattern by which the spread of dental caries occurs as it enlarges and deepens differs in these two types. Pit and fissure carious lesions begin in the depth of pits and fissures which form from incomplete fusion of enamel lobes during tooth development and are nearly impossible to keep clean. Fissures and pits are commonly located on the occlusal surfaces of posterior teeth (molars and premolars), as well as on the lingual surface of maxillary molars, the buccal surface of mandibular molars, and the lingual fossae of maxillary incisors, especially lateral incisors. In contrast to pit and fissure caries, smooth surface carious lesions occur on the smooth surfaces of the anatomic crown of the tooth in the areas which are least accessible to the natural cleansing action of the lips, cheeks, and tongue. The pattern of spread within enamel for smooth surface caries is different from that for pit and fissure caries since it begins as a relatively broad area of destruction just beneath the outer layer of enamel, but it narrows as it progresses more deeply toward the dentinoenameljunction. Once it reaches dentin, however, it spreads out wider at the dentonoenameljunction, just like pit and fissure caries. Root surface caries is another type of smooth surface caries that occurs on cementum, most frequently in patients with disease of the periodontium, patients with decreased saliva flow, or in older patients who have had gingival recession which increases the potential for accumulation of caries-forming plaque on the cementum of root surfaces. Treatment in these cases can include polishing the root, applying fluoride (topical or fluoride containing varnishes), and keeping the roots clean through good oral hygiene. In 1908, Dr. G.V. Black developed a comprehensive method of classifying carious lesions that has been useful when describing specific principles of cavity preparation. The original classifications were G. V. Black Class I, II, III, IV, and V. All pit and fissure type lesions are Class I, whereas Class II, III, IV, and V caries are all smooth surface type lesions. Notes: pit - ямка, углубление fissure - фиссура зуба lobe - доля
accessible - доступный, открытый gingival recession - рецессия десны, атрофия десневого края smooth - гладкий, ровный polishing - полировка, полирование comprehensive - глубокий, всесторонний; тщательный, подробный, детальный Exercise 9.

Read and tranlate into Russian the following text. DISEASES OF THE MOUTH The mouth, in which the preliminary process of digestion begins, has a number of functions to perform. A disturbance of any of these functions indicates the presence of disease in the mouth or at some distance, as in the stomach, and bowels. In the mouth the starchy portions of the diet are given their first digestion. The absence of a number of teeth or the presence ofbad teeth may disturb the preparation of food affecting the process of digestion in the mouth as well as in the stomach. One of the commonest mouth diseases is periodontitis. This disease occurs usually during middle or late life. In some cases it may result from infection due to lowered resistance within the teeth and gums. The teeth may loosen and separate, the gums becoming inflamed. Stomatitis refers to a condition characterized by inflammation of the oral cavity. Stomatitis is an inflammation of the soft tissues of the mouth occurring as a result of mechanical, chemical, thermal, bacterial, viral, electrical, or radiation injury, or reactions to allergens, or as secondary manifestations of systemic disease. There are various types of this disease such as: catarrhal stomatitis, chronic stomatitis, simple stomatitis, chemical stomatitis and so on. In stomatitis infection and inflammation of the mucous membrane of the oral cavity may involve the gingiva, the palate, the tongue, the cheeks: and the lips. The lesion may be of local origin or it may be a symptomatic expression of general disease.
Simple Stomatitis. The mucous membrane of the oral cavity being inflamed, becomes sensitive and red. Often the tongue and pharynx are involved. The temperature may rise very high, especially in children. Mastication is often interfered, the breath being fetid. It may be due to catarrh of the upper air passages or digestive disturbances. Idiosyncrasy to certain drugs may produce stomatitis, especially antipyrin, aspirin. Chemical Stomatitis. Under the term «chemical stomatitis* certain industrial diseases come, such as phosphorous and lead poisoning. The phosphorous stomatitis starts with a painful inflammation of the soft tissues and later causes necrosis of thejaws. In lead poisoning the gums look rather anaemic, the gingiva showing the typical narrow band of dark blue colour. Acute Herpetic Stomatitis is the manifestation of clinically apparent primary herpes simplex characterized by regional lymphadenopathy, sore throat, and high temperature, followed by localized itching and burning, with the formation of small vesicles of an erythematous base that give way to plaques and then painful herpetic ulcers. The gingivae are swollen and erythematous, and they bleed easily. Manifestations subside in 7 to 10 days, and recovery usually occurs within 2 weeks. Aphtous Stomatitis refers to recurrent ulcers of the mouth that appear to be the same clinically as herpetic ulcers and for that reason have been considered to be a manifestation of recurrent herpes simplex, although the herpesvirus has never been conclusively isolated from recurrent aphthae. Gangrenous Stomatitis is a destruction of large masses of the oral tissues, particularly the cheek. It usually is found in weakened patients with very low resistance to infection because of lowered white blood cell count or other causes. In advanced stages a large segment of the cheek may be lost, leaving the teeth visible through the defect. Herpetic Stomatitis is an oral manifestation of primary herpes simplex infection. The term also is used by some for herpetiform ulcers considered to be oral manifestations of secondary or recurrent herpes simplex. Medicamentosa Stomatitis is an allergic response of the oral mucosa to a systemically administered drug. Possible manifestations include asthma, skin
rashes, leukopenia lymphadenopathy, and oral lesions (erythema, ulcerative lesions and angioneurotic edema). Nicotinic Stomatitis is an inflammation of the palatal minor salivary ducts caused by irritation by tobacco smoke or hot fluids and characterized by raised small palatal lesions with red centers and white borders. The palatal mucosa usually has a generalized keratosis accompanying the smaller lesions. Also called stomatitis nicotina. Stomatitis Venenata is an inflammation of the oral mucosa as the result of contact allergy. The most common causative agents are mouthwashes, denture powders, and topical anesthetics. Possible manifestations include erythema, angioneurotic edema, burning sensations, ulcerations, and vesicles. Every dentist should be familiar with various types of stomatitis and recognize them clinically. VOCABULARY EXERCISES Exercise 1.

Exercise 3. Read the text below and answer the questions given after the text. PERIODONTAL DISEASE Periodontal disease develops slowly. The irritants in plaque inflame the gums, making them tender and easily bleeding. The unremoved plaque hardens and collects under the gumline, making plaque removal more difficult. More plaque forms, further irritating the gums and making them red, swollen, tender, bleeding. This condition is known as gingivitis and it can be controlled by scrupulous oral hygiene and professional cleaning. If gingivitis is not treated, it develops into periodontitis. In periodontitis, the irritated gums pull away from the teeth, forming pockets between the teeth and gums that fill with bacteria and gradually deepen. When that happens, surgery may be needed to save the teeth. If left untreated, the bone supporting the teeth is destroyed, and the teeth begin to shift and loosen. Eventually, they fall out or must be extracted. Questions to be answered: 1 .What are the symptoms of gingivitis? 2. What is the immediate cause of gingivitis? 3. How can gingivitis be controlled? 4. What are the main symptoms of periodontitis? Exercise 4. Read and translate the following text into Russian. YOUR GUMS ARE IN TROUBLE There are many signs of periodontal disease: swollen, painful or bleeding gums, bad breath, and loose or sensitive teeth. But gums don't always let you know they are in trouble, even in the late stages of disease. Bacterial infection may be silently and progressively destroying the soft tissues and bone that support your teeth. Early diagnosis of periodontal disease, prompt treatment and regular checkups bring the best results. Periodontal disease is a serious and often ongoing condition, it requires an ongoing treatment programme to control it effectively. After a thorough evaluation, your periodontist will recommend the best course of professional treatment. Whether this means non-surgical or surgical treatment, it always includes home care. The periodontal therapy you get in the dentist's office takes care of the infection you have now and helps maintain control. But only you can provide the daily flossing,
brushing and other care needed to prevent periodontal disease from getting worse or coming back. A periodontist is a specialist who specializes in the diagnosis, treatment and prevention of periodontal disease. In addition to four years of dental school, your periodontist has had extensive training in this specialty. He or she will provide you with treatment that ranges from deep cleaning of teeth and gums to surgical removal of infection to surgery that actually may restore soft tissue and bone, damaged by periodontal disease. Many periodontists also treat temporomandibular joint disorders (TMD), and are skilled in replacing missing teeth with dental implants. Exercise 5 A) Find words in the text which mean: 1) to supply what is needed; 2) examination; 3) teeth, moving more freely than is right or usual; 4) the process of giving medical or surgical care; 5) keep up, continue; 6) full; 7) prophylaxis; 8) absent. B) Complete these phrases with a verb.

Exercise 8. Read the following text. Pay attention to the following questions and give the main idea of the prophylaxis of periodontitis. PROPHYLAXIS OF PERIODONTITIS Why do we have to brush our teeth? To remove dental deposit and avoid different gum diseases. Every day a sticky film appears on the tooth surface. This film consists of bacteria that accumulate in places hard to reach and especially between teeth and on the gum border. That may cause various diseases of the teeth such as caries and periodontitis. What is the difference between tooth deposit and dental calculus? Bacteria deposits interact with minerals contained in the saliva and gradually harden. That is the way for dental calculus to appear. Dental calculus can be removed only by means of professional hygienic tooth cleaning performed by a doctor. What does a healthy gum look like?
A healthy gum is pale pink, strong and dense. It's snug against necks of teeth. While being brushed healthy teeth don't bleed. How does periodontitis appear? If you don't remove tooth deposits for a long time bacteria produce toxins that cause gum inflammation. It is the first stage of the disease or gingivitis. What are the symptoms of periodontitis? Inflamed and bleeding gums, unpleasant taste in your mouth, smell from your mouth, gradually progressing mobility of the teeth. How does the inflammation appear? When a bacterial deposit grows and reaches the gingival margin (a small cavity between tooth and gum) deeper periodontium layers get inflamed. Pathological periodontal sinuses appear. As a result bone tissue also gets inflamed and that causes its destroying. The more bone tissue is destroyed, the more is tooth mobility, and so suppurative inflammation (abscess) can appear within periodontal sinuses. Sometimes a gum lowers leaving dental roots naked. What is the daily periodontitis prophylaxis? At home you should try to completely remove dental deposits. Most people can't even imagine how difficult is to remove a tooth deposit and especially on a gingival margin. While brushing teeth people usually miss one and the same place . It is in these zones that inflammation usually appears. To avoid it a doctor performs a test with a dye to find out where dental deposits usually remain after brushing. With the doctor's help you can become familiar with effective dental care. Good oral hygiene makes your breath fresh and your gums and teeth healthy. Why is it necessary to have professional hygienic cleaning of the teeth? There are places that are hard to reach (interdental spaces and periodontal sinuses) where it's impossible to remove bacteria deposits and dental calculus without any help. People who smoke and drink strong tea or coffee usually have darkened teeth.
Professional hygienic cleaning of teeth removes dental deposits, it renews natural enamel colour. So it's better to have professional hygienic cleaning of teeth regularly. Professional hygienic cleaning involves: 1. Deposit colouring and individual consultation concerning hygiene. 2. Removal of dental deposits and dental calculus; periodontal sinuses and interdental spaces are cleaned with the help of an ultrasonic device or manually. 3. Renewing of natural enamel colour and whitening with an airflow method. 4. Tooth surface polishing. 5. Fluoride treatment. Exercise 9. The text to be translated in written form. Dental diseases are not different from other diseases but they are comparatively easy to diagnose, because the affected tissues are open to observation. The most common dental diseases are caries, gingivitis and pyorrhoea. Dental caries may affect enamel or it can involve both enamel and dentine. Gingivitis is an inflammation of the gum margin or gingiva that may in time involve the underlying and adjacent structures. Pyorrhoea occurs usually during middle or late life. There maybe an oedema of the periodontal membrane, in which case the teeth are raised in their sockets and elongated, and yet this condition is not actually pyorrhoea since there is no infection. Pyorrhoea exists when there is a partial destruction of the periodontal membrane and purulent discharge indicating infection. In the treatment of pyorrhoea it is necessary to remove all sources of irritation. Diet plays an important role in building up the local tissue resistance. Exercise 10. Reading for information. Use a dictionary if necessary. APICAL PERIODONTITIS The changes in the periodontal ligament around the apical foramina cause an increased pressure, producing sensitivity to percussion, occasional elevation of the tooth in its socket, creating trauma and pain on chewing. The complications of apical periodontitis may occur in four forms: the periapical granuloma, the apical periodontal cyst, the periapical abscess, and osteomyelitis.
The granuloma grows slowly and produces few clinical signs. The same is true of the apical periodontal cyst, until it becomes so large that it expands the cortex of the maxilla or mandible. Both are readily seen on radiographs. Apical periodontitis and its sequelae are treated by endodontic therapy or extraction of the tooth. When this condition is accompanied by systemic symptoms, antibiotic therapy may precede the definitive dental therapy. PERIODONTAL DISEASE AND DIABETES Periodontal diseases affect the soft tissues and bone that support the teeth. Gingivitis or inflamed gums, is the early form of periodontal disease. If left unchecked, gingivitis can progress to a more severe condition called periodontitis. This infection, caused by harmful bacteria, eventually destroys the bone and ligament which hold the teeth in place. Sound teeth may become loose and, if untreated, can be lost. For people with diabetes mellitus, periodontitis can be a major complication of their disease. Periodontal infection can upset blood sugar control, and loose or missing teeth can make eating the right foods difficult. WHAT CAUSES PERIODONTAL DISEASE? Dental plaque plays a major role in the development of gingivitis and other periodontal diseases. Plaque, a sticky film containing millions of bacteria, attaches to the teeth. Only certain types ofbacteria, however, are suspected of causing gum disease. Dental scientists are studying these and other harmful organisms to determine the exact roles they play in periodontal problems. Other factors that contribute to gum diseases include poor nutrition, inherited defects in infection-fighting cells, hormonal changes in pregnancy, and certain diseases such as diabetes mellitus. Periodontal diseases are a problem for many people. In fact, the majority of the population above the age of 40 probably have some form of the disease, ranging from mild gum inflammation to severe periodontal infection. Although most of the damage from gum disease occurs after the age of 35, dental scientists believe that the disorder has its beginnings in youth. Most school children have gingivitis, and some even have the more destructive form of periodontal disease. A GUIDE TO DENTISTRY • Lasers - used instead of drills to treat soft tissues (like gums), although they can't cut through dental enamel.
• Infra-Oral Cameras - pen-shaped devices used to take snaps of your teeth. The image can be flipped onto a monitor to explain treatment. • Porcelain Laminates - the veneer material that most closely resembles natural tooth. Surface details, colour and texture look natural. Veneers can be made as thin as 0.5 mm yet last for 15 years. • Resin Laminates - slightly cheaper than porcelain but don't look as good or last as long, say dentists. Resin is porous, takes up stains and has to be replaced every 2-4 years like white fillings, making it more expensive in the long run. • Dental patches - an alternative method of pain control. They stick to gums like a plaster and administer a dose of anaesthetic. Great for injection phobics, although they can be tricky to keep in place, according to dentists. • Glass Ionomer Fillings - bond chemically to the tooth and act as a fluoride source, but they can't be used on biting surfaces. • Injections - needles are getting finer and less painful.

Read and translate the following text into Russian. FIVE STEPS TO DENTAL HEALTH Dental health is an important part of total well-being. Nearly all dental diseases tooth decay and periodontal (gum) disease - are preventable. All you have to do is to follow these five steps to dental health: 1. Brush and floss your teeth thoroughly at least once a day. Toothbrushing is wellknown to remove plaque from the outer, inner and biting surface of the teeth. Tooth decay and periodontal disease often start in those areas where a toothbrush cannot reach. Only flossing removes plaque from between the teeth and under the gumline. 2. Brush your teeth after meals when you can. Remember to brush gently with short strokes and enough pressure, changing the tooth brush position frequently. 3. Eat a balanced diet. Dietary habits and the patient's attitude to them are of prime importance since diet is one of the main factors in the development of the dental
problems. The relationship between diet and dental health is considered to be very complex and involves many factors, such as the amount of carbohydrate containing foods (sugar and starchy foods) consumed, when and how often you eat, the types of food eaten, the period of time that food remains in the mouth, etc. 4. Use fluoride daily. Fluoride history is also of importance since the fluoride ion delays lesion progression. It is always wise to check that a fluoride toothpaste is used. Use a fluoride toothpaste. Fluoride is known to combine with tooth enamel improving its resistance to decay. Recently fluoride mouthrinses and mouthwashes have become widely used. In addition to brushing and flossing these products can effectively help to prevent tooth decay. 5. Visit your dentist for regular examination, professional cleaning of teeth and early identification and treatment of dental problems. Clinical examination is the most useful indicator of different diseases of the mouth cavity. Note: a stroke - зд. взмах, отдельное движение VOCABULARY EXERCISES Exercise 1.

Note: Must expresses a strong obligation; have to expresses a general obligation based on a law or a rule; should expresses advice, or a mild obligation.

CARE OF CHILDREN'S TEETH Even though baby teeth fall out and are replaced by adult teeth, it is important that they are retained for the proper time and not prematurely lost. Early loss of baby teeth can effect the development of the adult teeth and may result in need for orthodontic treatment, as well as alteration of facial structures, speech and eating ability. First teeth need regular cleaning in order to remove plaque, a sticky substance composed of bacteria and food debris. Plaque begins forming on the teeth as soon as they have erupted into the mouth. Bacteria in the plaque feed on sugars and produce acids. When food, containing sugar is eaten, some of it sticks to the plaque and is turned into acid by plaque bacteria. The acid forms within the plaque and dissolves the underlying enamel to produce caries. It must be explained to expectant and nursing mothers that caries cannot be prevented if plaque is not thoroughly removed daily. Before the teeth erupt, baby's gums should be wiped gently with a soft wet washcloth (салфетка из махровой ткани) once a day, preferably at bedtime. When the teeth start appearing, a washcloth should be used to clean them and then progress to a soft child's toothbrush. Inappropriate feeding of children can lead to the type of caries called Baby Bottle Tooth Decay (early childhood caries). Infants should not be put to sleep with a bottle containing milk, juice or other sweetened liquid. Infants should start to supplement their diet with non liquids at 4-6 months of age. Oral hygiene should be started with eruption of the first primary tooth.

Read the text and try to answer the questions given after the text Entitle it. How much does your health mean to you? Do you understand the importance of disease prevention? Everybody must remember: if you smoke, STOP. If you don't smoke, DON'T START. In addition to chronic bronchitis, emphysema, heart disease and lung cancer, there is also the risk of cancer developing in the throat and mouth. Nine thousand people die each year from oral cancer, and smokers have the risk of dying from oral cancer five times greater than non-smokers. It's a tragedy that can be prevented. Alcohol consumption is also considered to be the risk factor for developing oral cancer.
In addition to these 2 definite risk factors - tobacco and alcohol - there are other risk factors. They include poor dental health, inadequate diet, geographic location and occupation. Men are more likely to develop oral cancer than women. The disease can involve lips, tongue, floor or roof of the mouth, the inner lining of the cheeks, gums and other intraoral tissues. Many of these symptoms are painless and people ignore them. This is a serious mistake. The sooner the cancer is diagnosed, the sooner the treatment can begin. Early detection of oral cancer makes successful treatment possible. Questions to be answered: 1. Can cancer be prevented? 2. What risk factors are mentioned here? 3. Why is smoking so dangerous? 4. Do many people die of oral cancer? 5. Who are more likely to develop oral cancer: men or women? 6. What organs does the disease involve? 7. Are the symptoms painful? 8. What makes successful treatment possible? Exercise 4. Read the text and discuss it. DIET AND DENTAL HEALTH Generally speaking a diet adequate for normal growth and development of the body is adequate for building and maintaining the health of the teeth and their supporting structures. Calcium is essential for the development of teeth, and it is during the years the enamel is forming that this element is so important. The enamel begins to develop about five months before birth and is usually completed by eight years except for the wisdom teeth, crowns of which are completed between 12 and 16 years of age. An inadequate supply of calcium during these years may result in poorly formed teeth. Once the teeth are completely formed and calcified and have erupted in the mouth, no more calcium is necessary for their growth. Calcium will, however,
be needed throughout the whole life since it is essential to the body for other reasons, one being the development and maintenance of the bones. The health of the teeth and gums would benefit if people ate fewer highly cooked, refined foods and ate more of the granular, fibrous foods. Soft foods often impact between the teeth and cling to their surfaces, whereas the coarse foods tend to brush off and clean the teeth. Chewing coarse foods also will cause the teeth to move up and down slightly in their sockets, which is conducive to their health. It would, of course, be impossible to remove all highly cooked foods from the diet and it would not necessarily be desirable. Eating of more fibrous foods, such as fresh fruits and vegetables should however be encouraged. Sugar is an important factor in causing tooth decay, it is therefore desirable to restrict the use of sugar in the diet. Children especially should be encouraged to limit their intake of sweets to mealtime and to substitute such foods as milk, fruit, uncooked vegetables, and nuts for confections between meals. This is one way that all children can help prevent decay in their teeth. Exercise 5. Here are some answers. Write down the questions. 1. What_? Calcium is essential for the development of teeth. 2. When_? The enamel begins to develop about five months before birth. 3. What_? An inadequate supply of calcium may result in poorly formed teeth. 4. Why_? Since it is essential for the development and maintenance of the bones. 5._? The coarse food brushes off and cleans the teeth, chewing coarse foods also causes the teeth to move up and down slightly in their sockets, which is conducive to their health. 6. What_? Sugar is an important factor. 7. How_?
It is necessary to limit the intake of sweets to mealtime in children. Exercise 6. Read the text and pay special attention to the following points. 1. Eat plenty of raw vegetables. 2. End the meal with a fruit. 3. Avoid eating between meals. 4. Avoid very hot as well as very cold foods. 5. Brush teeth after a solid meal and gargle after a sweet drink. 6. Restrict sweets. 7. Chew the food thoroughly before swallowing. It is good for the teeth and for the body. WE ARE WHAT WE EAT... Good health is the vital part of the great experience of living. To achieve this adequate food of the right type is the foremost necessity of health. People with a poor diet are more likely to have dental problems. Calcium has proved to be essential for teeth and gums even from the time of prenatal life. Dairy products, fish, green leaf vegetables are considered to be sources of this mineral. Vitamin D found in sunlight and oily fish appears to aid in calcium absorption. Fluoride is known to be necessary in early life for the formation of caries resistant teeth. But it is reported to be a double-edge nutrient, its deficiency as well as excess can cause dental problems. Fluoride can be found in water, carrots, fish, tea. Such minerals as phosphorous and magnesium are also believed to be essential for the formation of the tooth enamel. These are found in meat, fish, eggs, spinach, bananas and whole wheat. Foods containing starches and sugar are well known to cause tooth decay. Starch is present in cereal, bread, vegetables, fruits and processed foods. Eating snacks between meals, especially sweets, sipping sugary drinks have been found to increase the risk of tooth decay. Starches are broken by saliva into simple sugars that are converted to enamel destroying acids by the bacteria in the mouth. Starchy foods that stick to the teeth are most likely to cause tooth decay because acids formed from them remain in contact with enamel. Cheese is reported to help fight tooth decay caused by sugary foods. Drinking tea without addition of sugar is also
recommended to prevent dental decay. Epidemiological surveys have reported that some populations who drink tea on a regular basis have a reduced number of carious teeth. Bleeding gums appear to be a sign of vitamin С deficiency. Protein and vitamin A deficiency also influences immune status.

Read and translate into Russian the following text and answer the questions. PREVENTIVE DENTISTRY Preventive dentistry includes cleaning the teeth, removing plaque, and advising patients how to brush teeth properly and how to use dental floss (a thread which removes food particles trapped between the teeth). Studies have shown that tooth
decay is decreasing in many countries as a result of preventive dentistry, improved diet, dental care, and the use of fluoride. Fluoride is a substance which can reduce tooth decay, and can be incorporated in the tooth enamel by taking tablets or drops, or by using a fluoride toothpaste. It occurs naturally in some drinking water but is also added artificially in a ratio of one part per million. The form of treatment known as orthodontics involves first X-raying the teeth, then using braces and other devices to straighten them, to even out any gaps, and to make the teeth, gums andjaws work correctly. This treatment should be carried out while the teeth are still growing and developing, but, in a few cases, orthodontic treatment is carried out on adults. Another branch of dentistry, called periodontics is concerned with the treatment of gum disease, which is a particular problem among older people. Like tooth decay, gum disease is also caused by excess plaque, which irritates the gums and eventually leads to receding gums and loss of bone. Lacking support the teeth become loose and have eventually to be extracted. Regular removal of plaque is very important in the fight against gum disease. People who have lost most or all of their teeth go to the dentist to have dentures, or false teeth, fitted. In the past, dentists made sets of false teeth using real human teeth or carved ivory. Today dentures are made from a plastic called acrylic resin or from metals such as chrome, cobalt, stainless steel, or gold. Plastic or porcelain teeth can be tinted to look like natural teeth. Dentures may be either complete (when all teeth are missing) or partial (when the patient still has some teeth left). Questions to be answered: 1. What measures does prevention in dentistry include? 2. Why is plaque removal so important? 3. What chemical substance, when added to drinking water, can reduce tooth decay? 4. How much fluoride is usually added to drinking water? 5. In what cases is orthodontic treatment necessary? 6. What methods help orthodontists in their treatment? 7.

Read and translate the text into Russian. PUBLIC HEALTH IN RUSSIA Health service in Russia is controlled by the state. As in many other countries, the public health service in Russia is free of charge. All types of medical aid including surgical intervention are available to everyone. No matter where a person lives, he can always call in a doctor and get a qualified medical aid. All expenses are borne by the state which has a wide network of medical institutions: hospitals, polyclinics, maternity homes, emergency aid
stations and so on. Along with these, there are many medical institutions which provide medical assistance for money, such as joint ventures or self-financing polyclinics, for example. In-patient departments of the state medical institutions have the total of 35 million beds. Over one million doctors and more than three million paramedical personnel are involved in thejob of taking care of the people's health. Hospitals consume a lion's share of state allocations for health - about two thirds of the total sum. New large hospitals and specialised centers are set up. Much is done to increase the output of the latest types of medical equipment including radio electronics and nuclear physics. Everybody knows that it is much easier to prevent a disease than to treat it. The famous Russian surgeon N. Pirogov wrote that the future belongs to preventive medicine. Prophylaxis is one of the basic principles of the Russian public health system. Annual medical check-ups are carried out at every district polyclinic or large factories and farms with the aim of detecting diseases at the earliest stages of their development. Dental service in our country is also planned and controlled by the state. Dental care is provided free of charge in specially equipped dental polyclinics and inpatient departments. The majority of dental clinics are furnished with modern equipment, have X-ray rooms, physiotherapy units and oral health care rooms. The assistance is rendered by various specialists: dental therapeutists, surgeons, prosthetists, dental mechanics and orthodontists. Prevention in dentistry is just as important as in general health care. Neglected dental disorders lead to complications that sometimes may be very serious or even fatal. So, the national strategy for dental care is prevention and timely treatment of diseases of the teeth and oral cavity. People are recommended to undergo prophylactic check-ups once or twice a year to protect themselves from dental diseases. Like everywhere in the world, medical science in Russia concentrates on the solution of most important health problems such as the development of new ways and means of prevention and effective treatment of cardiovascular diseases, cancer and many other dangerous diseases both congenital and developed. Much attention is paid to the prevention and treatment of tooth decay and other diseases of the teeth and mouth cavity. VOCABULARY EXERCISES

THE NATIONAL HEALTH SERVICE OF GREAT BRITAIN The British National Health Service came into existence in 1948, to give completely free medical treatment of every kind to everyone needing it. Since then some payment has been brought in for one item after another, beginning from 1951 when patients had to pay a small fixed amount for pills or medicine prescribed for them. Children, pregnant women, old people and the poor were exempted from some of these charges, but in 1988 the Government began to abolish some general exemptions for pensioners. People who are ill go first to see their general practitioners (GPs), who treat minor illnesses themselves. These family doctors work alone or in partnerships with surgeries or bigger urban medical centres, and when necessary go to see patients in their homes. Everyone is normally on the list of a general practitioner (or family doctor), who keeps full records of all treatments and over the years gets to know 2,000 or more people on his or her list. General practitioners refer people to hospital, if necessary, for more specialized treatment, also free of charge both for outpatients and for those who have to stay in hospital. Most dental treatment is carried out in the dentists' surgeries though difficult cases are sent to dental hospitals. The dentists are paid from health service funds for each item of treatment. At first their patients did not have to pay, but later payment became necessary, and now people must pay even for checkups. Only children and few other groups of the population are exempted.

There are three main departments in such polyclinics: a department of therapy, oral surgery and orthodontics and prosthetic dentistry department. Some laboratories and X-ray rooms are also attached to every dental polyclinic. If you have some trouble with your tooth or a bad toothache you should consult a dentist. He will examine your teeth and if the aching tooth is not far gone he will stop it. He'll clean and drill your tooth and then put in a filling. If your cavity is neglected (far gone) and it hurts you the dentist will treat your tooth. In case the tooth is too bad to be stopped or treated, the dentist will pull it out (extract a tooth). Before extracting a tooth he will apply some anaesthetic or give an injection to deaden the pain.
If you have some inflammation or an abscess in your mouth, if the teeth become loose and gums bleed, you should consult an experienced specialist. He will diagnose your case and prescribe a proper treatment. If an operation must be performed in the mouth cavity, a qualified oral surgeon will operate on you. If you need dentures, bridges, some false teeth or crowns you must consult a dental mechanic and he will do everything you need. If you have instanding or outstanding teeth, overcrowded teeth or malocclusion, you must consult an orthodontist and get it corrected. Regular visits to a dentist, once or twice a year, proper oral care and good eating habits (a limited consumption of sweets in the first place) will protect you from many dental diseases.

HOW HALF OF DENTISTS TURN THEIR BACKS ON NHS PATIENTS More than half of English dentists have closed their doors to NHS patients, a survey reveals. The research found 51 per cent of dentists were only taking on patients if they agreed to go private. In some areas, the situation is so bad that only 15 per cent of dentists are taking on NHS patients, the study by consumer magazine «Which?» showed.
The research comes a week after Tony Blair admitted for the first time, that Labour had broken its pledge to ensure everyone had access to an NHS dentist. Liberal Democrat health spokesman Norman Lamb said the figures showed NHS dentistry is 'becoming a thing of the past'. 'What is most worrying is that many people on low incomes are effectively excluded from dental care' he added. 'One 80-year-old woman who came to me needed teeth taking out and new false teeth putting in.' 'She was told that would cost between 500 and 800 to have done privately because she can't get an NHS dentist.' Researchers from «Which?» posing as potential patients contacted 466 dentists. The survey showed the worst area for access was the North West, where only 13 per cent of dentists are taking on NHS patients. Following closely behind were Yorkshire and the Humber on 15 per cent, and 16 per cent in the South Central region. The best areas for NHS dentists were the West Midlands, on 63 per cent, and London on 59 per cent. Those living in rural areas suffer the most - just 16 per cent of dentists in the countryside provide NHS treatment, compared with 39 per cent in towns and cities. The situation was even worse for NHS emergency appointments, which were offered by only 5 per cent of dentists in the North West and South West. Last month a survey by Citizens Advice found around two million people in England who would like access to NHS dentistry are unable to do so. Two thirds of them simply go without treatment rather than going private. Recent surveys by «Which?» have also highlighted patients' dissatisfaction at the state of the rest of the health service. Only 18 per cent were happy with the quality of hospital food, with 29 per cent of patients - and 57 per cent of new mothers - feeling hungry after meals. Another survey of 2000 patients found many did not know where to turn for out-of-hours care, with only two in five calling the NHS Direct helpline. Frances Blunden of «Which?» said: The Government has allocated enormous amounts of money into the NHS but on the ground the public are seeing cuts in services and considerable difficulties getting treatment.
'In dentistry we have found that where needs are not currently being met, people are either putting off having treatment or are being forced to go private.' Tory health spokesman Andrew Lansley said: 'After ten years of Labour's financial mismanagement patients are being told they can't have operations, nurses are on the brink of strike action, maternity units and accident and emergency are being threatened with closure, and 10 000 talented junior doctors are left withoutjobs'. Tony Blair and health secretary Patricia Hewitt are due to defend their record in front of the King's Fund think tank today.

Gone are the days when most patients attended their dentist or other professional adviser, sought and accepted his or her advice without question, and felt almost detached from the process. Although patients used to do things «under doctor's orders*, many now take a much more lively interest in the management of their own health. Along with this involvement, which many patients seek and which should be encouraged in those who do not, comes a responsibility for participating in decisions about their own welfare. In the final analysis, it is patients who will decide whether they will attend for treatment, whether they will clean their teeth effectively, and what sacrifices of time, effort, and finance they are prepared to make. A dentist's role is to offer advice and, if the advice is accepted, provide treatment. This advice can usually be classified as follows: • diagnosis • prognosis • treatment options • prevention of further disease. These matters will be dealt with in more detail shortly, but first it is necessary to understand the nature and status of this professional advice. The professional-client relationship is special in that professional people take upon themselves the duty of setting their client's interests above their own. It is this aspect of professionalism which engenders trust in patients and explains, why they
so often accept the advice of the dentist. Once this professional relationship begins to break down, as it does if the dentist puts his/her own interests before that of the patient then the patient's confidence is lost and he/she begins to mistrust the dentist's advice. In order to give advice the dentist will need information, and a large part of the chapter is taken up with describing what this information might be, and how it should be collected and collated. In some cases this information alone will be enough to enable the dentist to give advice and take a decision. However, in many cases another element, judgment, will need to be applied. If all diagnosis and treatment planning were straightforward, so that a given set of facts always resulted in the same treatment plan, the process could, and by now probably would, be undertaken by computers. Judgment based on the clinician's own experience and that of others is a second element in the essential nature of a professional person. Using the terminology of British law, some of these judgments can be made «beyond reasonable doubt* but others have to be made «on the balance of probability*. It is the skill and care with which thesejudgments are made that distinguishes the really good dentist from the merely good dentist. In difficult cases many experienced clinicians seek second or even third opinions, discussing the case with colleagues before reaching a final decision as to the best advice to offer the patient. Many decisions are rather routine in their nature and become automatic with practice, rather like the subconscious decision to press the accelerator to drive the car faster. While learning to drive, this decision, like many similar decisions in dentistry, has to be considered consciously. Other decisions may be slightly more difficult, such as whether all the dentine caries in a tooth must be removed and whether fissure caries has extended to the point where it should be restored or not, these decisions are always made at the conscious level. Then there are the much more substantial decisions which sometimes have to be made - for example, whether to advise a patient to have all his or her teeth extracted, or to have them all crowned or extensively restored, or to adopt some middle course of a few extractions with a simpler level of restorations and perhaps a partial denture. THE FOUR MAIN DECISIONS Diagnosis Diagnosis is the recognition of a disease. Sometimes a bald statement of the diagnosis is sufficient, or example, amelogenesis imperfecta. In most cases,
however, the diagnosis should include the extent, location, and other characteristics of the disease. For example, a diagnosis of caries or periodontal disease is not enough without describing where it occurs and how extensive it is. Prognosis The prognosis of a condition is the estimate of what will happen if it is not treated and what the consequences of treatment will be. Therefore the prognosis for an early enamel carious lesion is good if appropriate preventive measures are taken, whereas the prognosis for maintaining the vitality of the pulp if caries is so extensive that symptoms of pulpitis arise is poor. However, in the latter case, if other conditions are favorable, the prognosis for keeping the tooth if root canal treatment is carried out is good. Treatment options This often seems to be the most important decision, particularly for the patient, in that it affects what will be done. However, it is based so fundamentally on the first two decisions, diagnosis and prognosis, that it is, in reality, no more important, and often less so, then they are. Further preventive measures The long-term success of treatment is dependent in many cases on the patient's willingness and ability to co-operate in preventing further disease. A decision about the likelihood of this being effective should be attempted before the definitive treatment plan is decided, in particular if extensive treatment is contemplated. Thus the aim of an initial treatment plan may be to stabilize active disease, assess its cause, and start preventive measures. The patient's response to this initial treatment will be an important factor when planning subsequent care.Questions: 1. What must a diagnosis be based on? 1. In what cases is prognosis good and when can it be poor? 2. How important is treatment compared to diagnosis and prognosis? 3. What does the success of a treatment depend on? 4. When should a definitive treatment plan be decided? 5. What may the aim of an initial treatment plan be?
Exercise 8. Read and translate Part 2 of the above-mentioned text so as to be able to sum up the aide-memoire for the history and examination of a new patient. Part 2 THE INFORMATION NEEDED TO MAKE DECISIONS AND HOW IT IS COLLECTED AND RECORDED Part of the skill of an experienced clinician is to decide what information is needed, and to acquire it accurately and rapidly so that he or she is in the best position to give good advice without undue delay. Some clinicians adopt a «data gathering* approach in which, using check-lists, they try to accumulate all the information which would conceivably be of some relevance about a patient. Some information is essential for all patients, some is useful for most, and in others a very detailed investigation of a narrow field of interest is necessary in order to reach a diagnosis or make one of the other decisions outlined above. Figure 1 shows a list of information which may be helpful to a student when first meeting patients. It is not meant to be followed slavishly but it is a useful aide-memoire for the inexperienced. However, it is dangerous to begin the examination of a patient without first ensuring that it will pose no risk to either the patient or the dentist. For this reason a full medical history should be taken before the examination, irrespective of any other history. Lists such as the one in Figure 1 are oversimplification and suggest that the entire history should be taken first, followed by the examination of the patient. Some dentists even do this in two separate areas of the surgery, attempting to separate the conversational and clinical aspects of the process. This is often not practical and indeed may be undesirable. It is much better to mix the two processes together and maintain a steady conversation with the patient before, during, and after the examination, pausing to take notes or, better still, dictating them to the dental nurse or onto a tape as the process continues. The reason for this is that until the dentist has made an initial examination of the mouth it is often not possible to tell what detailed line of questioning to pursue. For example, if the patient complains of discolored teeth, a quick examination will show whether this is surface or intrinsic stain. If it is surface stain there is no need for questioning on the administration of tetracycline in childhood or the ingestion of excessive fluoride. Another common example is the patient who complains about his teeth ^crumbling away». This may be the result of caries and failing
restorations, tooth wear, or a developmental defect. Again, a quick examination will show which approach to the dietary history is likely to be most helpful - to pursue a detailed history relating to sugar or a detailed history relating to erosive materials - or whether, if it is a developmental disturbance, diet has no bearing on the matter at all. It is necessary here to describe the history and examination process in some sort of order, even if this order will seldom be followed comprehensively in practice. Exercise 9. Read and translate Part 3 of the text. Before you do, translate the following sentences. 1. This information is essential and it should always be checked for accuracy. 2. The patient's occupation may have a bearing on the condition itself (for example, industrial erosion) and may affect availability for treatment. 3. Direct questioning is usually unhelpful while attitudes may become apparent during conversation, particularly when past dental treatment and experience are discussed. 4. A question such as ' Do you think you have a sweet or a sour tooth?' can often elicit valuable information about attitudes as well as facts. 5. This is an example of how history and clinical examination go together to produce information relevant to the particular patient. 6. Any apparent discrepancy between what patients say that they do when they clean their teeth and the clinical condition may be cleared up by asking them to bring brush and paste to the surgery. 7. Previous treatment indicates susceptibility to disease as well as attitudes towards dental care. 8. Itis thus possible to build up a picture of past dental history which may include caries experience, restorative treatment received, susceptibility to periodontal disease, etc. 9. Attitudes to dental health, either positive or negative engendered within the family may have an important bearing on the condition with which the patient presents. The same is true of the patient's social background.
Fig. 1. Aide-memoire for the history and examination of the new patient. Part3 CASE HISTORY About the patient Name, address, telephone and Fax numbers
This information is essential and it should always be checked for accuracy. It is quite possible to have two people with the same name in the waiting room or the practice, and only careful and routine checking will prevent serious mistakes being made. Age, sex, occupation Age will have considerable bearing on the state of dental development in younger patients and is important for a variety of reasons at other ages. The patient's sex usually has no bearing on the treatment advised, although it is usually recorded to avoid confusion. It should not be assumed that female patients are more concerned with their appearance than male patients. The patient's occupation may affect availability for treatment. Attitude and motivation to dental health and treatment Whereas information about age and occupation is easily obtained by direct questioning, assessment of attitude to dental health and motivation is more difficult. Direct questioning is usually unhelpful because the patient will tend to answer the questions in a way which will «please» the dentist. However, attitudes may become apparent during conversation, particularly when past dental treatment and experience are discussed. Diet Since diet plays a major role in dental caries and can be of importance in tooth wear, a discussion about diet is often useful. A question such as «Do you think you have a sweet or a sour tooth?» can often elicit valuable information about attitudes as well as facts. For instance, the way that the patient answers such questions may reveal whether he or she appreciates the relevance of diet to dental disease and whether modification of diet has been tried in the past. However, a detailed examination of diet is reserved for those with specific caries or tooth wear problems which will only become obvious after clinical examination go together to produce information relevant to the particular patient. Habits It is useful to enquire about tooth cleaning habits and the toothpaste used, but other habits may also be relevant; for example, smoking will increase the likelihood of surface stain on teeth. Following clinical examination further questions may be needed; for example, a particular pattern of tooth wear may suggest questions about grinding habits, an erosive diet, or alcohol consumption.
Any apparent discrepancy between what patients say that they do when they clean their teeth and the clinical condition may be cleared up asking them to bring brush and paste to the surgery. Willingess to meet fees and other expenses Most dental treatment involves the patient in some expense. Usually it is not possible to estimate the fee or the amount of time involved until an outline treatment plan is established. Sometimes this «ideal» outline plan will be too costly for the patient and an alternative might have to be sought. It is important to establish this at an early stage before too much time is spent in detailed planning. About the patient's general condition and health Here a check-list is useful and questions are usually asked, and followed up when necessary, about the following: • history of heart or chest disease • current (or recent) medication • allergies • any difficulty in the arrest of hemorrhage after extraction or injury • previous hospital admissions • other diseases • pregnancy • contact with HIV or AIDS When these questions are answered positively it may be necessary to refer to the patient's general medical practitioner or to arrange further investigations (for example, blood tests) before proceeding with treatment. The patient's reason for attendance Some patients have an urgent problem such as pain or trauma, while other attend for a routine examination without particular symptoms. When symptoms are present the patient should be encouraged (without the use of leading questions) to describe these as clearly and in as much detail as possible. Past dental history Apatient's past dental history can be of considerable assistance. Previous treatment indicates susceptibility to disease as well as attitudes towards dental care. For
instance, the question «Have you had many fillings done?» may lead the patient to explain that most teeth have been restored. If this question is then followed up by asking whether most of the fillings are old or whether they have to be replaced regularly, the information obtained may indicate whether the patient is currently a high caries risk. It is thus possible to build up a picture of past dental history which may include caries experience, restorative treatment received, susceptibility to periodontal disease, periodontal treatment received, extractions and the reason for the loss of the teeth, and information about prosthetic replacements. Family and social background Where an inherited condition is suspected, clearly the distribution within the family is important. In other cases attitudes to dental health, either positive or negative, engendered within the family may have an important bearing on the condition with which the patient presents or upon acceptance of treatment. The same is true of the patient's social background. Other aspects of the social history for example availability for long appointments - will also determine the type of treatment. Exercise 10. Translate Part 4 of the text into Russian. Complete sentences that follow it with words and expressions from the text that are given in brackets. Part 4 EXAMINATION General appearance The patient may appear nervous or relaxed, fit and well or elderly or ill, clean and tidy or dirty and disheveled. These or similar observations will guide but should not dictate treatment. It takes time to get to know people and instantjudgments are unwise. For instance, a neglected general appearance does not necessarily mean that the person does not care about his dental health. Factors which predispose to cross-infection Some people - for example, drug addicts, homosexuals, or heavily tattooed patients - are more likely to be carriers of the hepatitis В virus and HIV (human immunodeficiency virus). The extra-oral facial appearance
The temporomandibularjoint and lymph nodes should be palpated. Any obvious asymmetry is noted and the lips are examined. Such things as injuries or scars on the lips may be accompanied by dental injuries. Where the patient's problem involves appearance, the dentist will make his or her own assessment of this while listening to the patient. The mouth in general Oral hygiene is relevant in both periodontal disease and caries. A general impression of whether the mouth is well cared for by both the patient and previous dentists is useful, but patients do sometimes increase their dental awareness considerably and previous neglect need not imply future neglect. Specific areas of the mouth The soft tissues A routine examination of the inner aspects of the lip, the tongue, and the buccal and lingual sulci should be made at all examinations since, amongst other things, early neoplastic change can be detected and early treatment can be life-saving. The periodontal tissues A general assessment of the state of periodontal health is always necessary. This will include oral hygiene; the presence of both supraand subgingival calculus, the health and position of the gingival tissues, the presence of pockets, and whether there is bleeding on probing and mobility of teeth. In many cases a more detailed periodontal examinations needs to be undertaken. Caries experience: past and present Again, a general impression can be gained of the extent of carious lesions and previous restorations. It is reasonable to assume that restorations are most commonly the result of caries but, of course, other conditions may also have been responsible. Other conditions affecting the teeth These include trauma, tooth wear, dental defects, missing teeth, and malpositioned teeth. The occlusion First, the static relationship of the teeth in intercuspal position (ICP) should be examined to determine the horizontal and vertical overlap of the anterior teeth (overjet and overbite), together with the relationship of the posterior teeth. Next,
and perhaps more importantly, the way in which the teeth function against each other in forwards, backwards, and lateral movements of the mandible should be examined. This is often relevant to the decision as to how to restore a tooth. If a cusp functions vigorously against an opposing tooth when thejaw moves, then it may need protecting in some way by the restoration, but if it immediately discludes in all movements of the mandible, it may not. Dentures The presence and nature of dentures should be noted. It is important to decide whether dentures are satisfactory or in need of replacement. Diet analysis The past and present diet can be investigated by questioning and by completing a diet sheet. Salivary analysis In patients with a high caries incidence, the salivary buffering capacity may be tested. Also, counts of Streptococcus mutans and lactobacillus in the saliva may be used to monitor the caries risk and the success of a caries prevention program. Sentences to be completed: 1. It_time to get to know people and instant judgments are_. 2. Oral hygiene is_in both periodontal disease and caries. 3. A general impression is useful, but patients do sometimes increase their _considerably and previous neglect need not imply future neglect. 4.

THE HISTORY AND EXAMINATION PROCESS Examination Process As stressed earlier, the full history is not usually completed before the examination starts. Although there are many variations, a common pattern of history and examination would proceed as follows: • reason for attendance; • medical history; • initial preliminary examination; • initial assessment of the patient's general oral and dental condition and the specific problem, if there is one; • further conversation to effect more details of the symptoms (if there are any), and the background to the problem which is likely to be relevant - for example diet, social history, etc.; • further detailed examination; • general assessment of the patient's dental awareness and expectations; • special tests; • start the treatment planning process. Whatever sequence is used for a particular patient, it is helpful if the findings are recorded in a systematic way. The record must always be made while the patient is present, and the need for a contemporaneous record cannot be overstressed both in the interests of accuracy and also for medico-legal reasons. Planning the treatment Treatment should follow a planned course in all cases. This is not to say that the plan is unalterable, and the temptation to write down a treatment plan as a prescription and then follow it without further thought or revision should be avoided. It is necessary to maintain constant vigilance for changes in the clinical circumstances, the patient's response to treatment, and the success of earlier stages in the treatment The general approach to treatment planning should be one of problem solving. This seems obvious, but is not always as simple as it sounds. One set of circumstances for example, a mild disturbance in the appearance of a tooth - might be a real problem to one patient, causing great distress, and yet go unnoticed by another.
Cosmetic problems like this can be regarded as the patient's problem and he or she will ultimately decide whether they want treatment or not. Other problems are more the dentist's. To continue with the same example, the dentist must decide between recommending a composite restoration (a facing of composite or porcelain, or a crown). The final decision is takenjointly between patient and dentist and illustrates another important principle of treatment planning. The patient must be properly informed about treatment alternatives and must give informed consent to the treatment. Treatment plans can conveniently be divided into «simple» and «complex». A simple treatment plan is by far the most common and is all that is usually required for patient and recall visits, sometimes over many years of maintenance of a good standard of dental health. In such cases the dentist is monitoring health. However, there is a danger of both dentist and patient being lulled into a false sense of security, and it is important that at each re-examination relevant questions are asked and a proper examination made so that slow and steady development of periodontal disease or secondary caries is recognized. A typical «simple» treatment plan would be as follows. 1. Reinforce oral hygiene procedures lingual to lower molars. 2. Scale and polish. 3. Replace stained composites as charted (and the dental chart might show two or three anterior composites to be replaced). A more complex treatment plan is often required for patients who have not attended for some time or where there is a need for a major reassessment of a declining state of dental health. In these cases it is helpful to divide the treatment into stages. 1. Urgent treatment for the relief of pain or other symptoms. 2. Treatment for the stabilization of progressive disease or conditions which may become acute (e.g. temporarily restore very carious teeth, remove necrotic pulps, or extract teeth even if they are symptomless at the time). 3. Assess the cause of the dental disease and begin initial preventive measures. 4. Reassess the patient's response to this initial treatment and decide the broad outline of the future plan. At this stage it may be necessary to decide between a number of alternative solutions of different complexity and cost. For example, the same clinical condition (a badly brokendown mouth with many failing restorations
and unsatisfactory partial dentures) may be treated in different patients by one of the following: • extracting all the remaining teeth and providing complete dentures; • providing extensive restorative treatment with multiple crowns and fixed bridges to replace the partial denture; • a midway position between these extremes with some extractions, some restorations and new partial dentures. The basis of this broad decision will be the patient's motivation, his or her response to initial treatment and preventive measures, and the cost. It is a crucial decision and one of the most difficult to make. If there is any doubt, it should be deferred or, better still, a second opinion should be sought from a colleague who may be a member of the practice or the clinic or a local consultant. In some cases, for example hypodontia, decisions may need to be made about orthodontic treatment before providing veneers or crowns and bridges. 5. Provide the initial stage of definitive treatment which may be further preventive measures, periodontal treatment, orthodontic treatment, extractions, or other surgical treatment. 6. A further reassessment to evaluate the success of the first stage of treatment and revise the treatment plan as necessary. 7. Provide the final stages of the active course of treatment. 8. Reassessment, maintenance, and reinforcement of preventive measures. The importance of making plans, both simple and complex, and of recording the decisions in the patient's record can be summarized as follows. • It ensures that the clinician reviews the treatment in the light of all available evidence at the start of treatment and at stages throughout it. • It is a record for later reference, particularly in complicated cases and after a lapse of time. This is available mostly for the benefit of the patient, but on occasions, when patients complain, it may have dento-legal importance and may protect the dentist against unjustified complaints. In this context, when the treatment plan is complex and expensive, it may be wise to put the advice in the form of a letter to the patient so that he or she has time to consider it and its implications before acceptance or rejection. The letter is also a written record, of which the patient has a copy, in cases where there is a dento-legal problem later.
• It avoids the risk of disorderly and ill-advised management which may arise if treatment is undertaken piecemeal. Unfortunately, this is a danger in clinics which are organized on a rigid departmental basis, so that a logical course of treatment is interrupted by different lengths of waiting lists in each department or by the student's inability to carry out certain items of treatment. In a learning environment some restrictions are necessary, but it is important that the compartmentalized attitudes they engender are not carried over into practice. Some common decisions which have to be made Clearly, it is not possible to give guidance on every decision which may have to be made, but the following set of examples illustrates the nature of the decisionmaking process. The examples are as follows: • diagnosing toothache • whether to restore or attempt to arrest and partially remineralize a moderately sized carious lesion and whether to restore or monitor an erosive lesion • whether to extract or treat a tooth • which restorative material to use. Making the diagnosis in a patient with toothache Although it is necessary to know the characteristic symptoms and signs of a condition, it is also necessary to have a systematic method of diagnosing the cause of symptoms in a patient with toothache. The history should concentrate on the nature of the pain, its duration, and initiating stimuli. Clues should be followed; for example, chronic sensitivity to sweet foods may suggest exposed dentine rather than any of the other conditions, and chronic tenderness to biting will suggest either a cracked cusp or perhaps chronic apical periodontitis. The past dental history may be of interest in cases where trauma or recent restorations may be the cause. On examining the patient, the dentist should look for possible causes such as caries, leaking restorations, cracked cusps, or evidence of trauma. Radiographs, vitality tests, and percussion tests are all required in order to be confident of a diagnosis in almost every case. Radiographs may show periapical radiolucencies, failed root fillings, internal or external root resorption, fractured roots, and other possible reasons for the toothache. Figure 2 shows the typical interpretation of signs and symptoms in toothache.
Finally, despite having completed a full investigation, there are occasions when the cause of the pain is still not clear. At this point it is wise to reconsider other causes of pain, such as trigeminal neuralgia, but if these can safely be eliminated then, and only then, the dentist should start to remove previous restorations. A simplistic maxim, but one well worth remembering, is ^diagnosis should precede treatment*. Far too often busy dentists, pressed for time, feel an obligation to start treating teeth without having made a through diagnosis of the cause of the toothache. Questions to the text: 1.

ENDODONTICS Endodontics is a subspecialty of dentistry whose broad purpose is to treat the diseases of pulp and related structures. Derived from Greek («endo» - inside and «donto» - tooth). Endodontics deals with problems developing inside the tooth. This involves careful cleansing of the interior spaces, germicidal treatment of these spaces and filling and sealing them. Endodontists are capable of performing a wide variety of treatment procedures. Endodontics is that branch of dentistry which is concerned with the diagnosis, prevention and treatment of diseases and injuries of the pulp and associated periradicular tissues, i.e. root canal therapy. This involves the removal of diseased pulp tissue and filling of the prepared root canal space with an inert filling material, normally gutta-percha. In addition to non-surgical treatment, endodontists also perform surgical procedures to remove diseased tissues from the area immediately surrounding the tip of the root(s). Root canal therapy corrects disorders of the pulp or nerve of the tooth. Teeth with infected nerves were once generally removed as corrective therapy. In case of pulp infection, natural tooth can be saved through modern endodontic procedures. The restoration of a natural tooth is always preferable in addition to prosthetics for a wide variety of oral health reasons. The most common causes of pulpal nerve damage are: • physical irritation, generally brought on by aggressive tooth decay reaching down to the nerve or through deep fillings which allow harmful bacteria to reach the nerve resulting in infection and decay; • trauma: many forms of dental trauma can affect the health of pulpal tissue. Blows to a tooth or thejaw can cause damage to sensitive nerve tissue within the tooth. Diagnosis of pulpal nerve damage is generally the result of pain and discomfort in the tooth that can be accompanied by facial swelling of varying degree. Once pulpal decay has been confirmed by an endodontist, through an oral examination, corrective therapy should begin quickly to avoid tooth loss and alleviate pain.
Treatment begins with the initial removal of the tooth crown or top, to allow access to the pulpal tissue. Once the affected pulpal tissue is exposed, the endodontist carefully removes all of the affected area. The area is carefully cleaned, enlarged and shaped to provide a clean, bondable surface for eventual filling. When the endodontist has completed the evacuation and shaping of the pulpal canal, it is then filled with a permanent filler to prohibit any further infection and discomfort. Upon completion of this filling an adequate crowning is then fabricated to complete the rescue and restoration of your natural tooth. Exercise 4.Read and translate the text into Russian using a dictionary. DENTAL ANOMALIES This text is designed to help the learner perform the following: • Identify variations from the normal (anomalies) for the number of teeth in an arch. • Identify anomalies in crown morphology and, when applicable, identify the anomaly by name and give a possible cause (etiology). Definition: An anomaly is a deviation from normal, usually related to embryonic development that may result in the absence, excess, or deformity of body parts. Dental anomalies are abnormalities of teeth that range from such «common» occurrences as malformed permanent maxillary lateral incisors that are pegshaped, to such rare occurrences as complete anodontia (no teeth at all). Dental anomalies are most often caused by hereditary factors (gene related) or by developmental or metabolic disturbances. While more anomalies occur in the permanent than primary dentition, and in the maxilla than the mandible, it is important to remember that their occurrence is rare. For example, only 1-2% of the population have some form of anodontia (one or more missing teeth), while another 1-2% have supernumerary (extra) teeth. When specific deformities or abnormal formations of teeth occur with greater frequency, it is difficult to determine whether the deviation is a «true» anomaly or simply an extreme variation in tooth morphology. Familiarity with dental anomalies is essential to the clinical practice of dentistry and dental hygiene. Recognition and correct labeling of anomalies is important for your communication with other dental team members, especially in the case of referral to or from another dentist. Additionally, your communication with the patient (or, in the case of a child, the parent) should reflect knowledge of abnormal oral conditions. Even with your assurance that the fused front tooth of a 4-year-old
child occurs with 0.5 % frequency and rarely affects the number of teeth in the permanent dentition, you will have to work hard to explain and promote the patient's confidence in you and the office. Likewise, the informed patient who understands why the accessory cusps on the buccal surface of his maxillary or mandibular molar is more prone to decay than normal, will likely be more receptive to home care instructions that are specific to his mouth and his needs. Finally, understanding the etiology (cause) of the anomaly is important in determining the course of treatment, if any. Additional information related to the etiology of the following anomalies is found in the study of both oral histology/embryology and oral pathology.

ABSENCE OF TEETH A) Total Anodontia True anodontia is the total congenital absence of a set of teeth. Total anodontia is characterized by the absence of the entire primary and secondary dentitions, and is extremely rare. It is most often associated with a generalized congenital deformation (a sex-linked genetic trait) such as the abnormal development of the ectoderm or outer embryonic cell layer. Faulty ectodermal development further affects such structures as hair, nails, sebaceous and sweat glands, and salivary glands. B) Partial Anodontia Partial anodontia, also referred to as congenitally missing teeth, involves one or more missing teeth from a dentition. Though not proven to be a hereditary trait, tendencies toward missing the same tooth do run in families. 1. Most commonly missing permanent teeth. The most commonly missing permanent teeth are third molars, with the maxillary thirds absent from the dentition more often than the mandibular thirds. 2. Second most commonly missing teeth. The permanent maxillary lateral incisors are the next most commonly missing teeth. Approximately 1-2% of the population is missing one or both of their maxillary incisors. 3. Third most commonly missing teeth. The mandibular second premolars are the third most frequently missing permanent teeth, with 1% of the population missing one or both. Some stud-
ies indicate the order of most commonly missing teeth to be: third molars, maxillary and mandibular premolars, and maxillary lateral incisors. Some observers state that missing teeth follow evolutionary trends in that the teeth most commonly missing from the dentition (third molars) are those that are most expendable in terms of their role in oral function. On the oposite, the most stable teeth in the permanent dentition, the canines, are the least likely to be absent from the dentition.

FUSION Fusion is the union of two adjacent tooth germs, always involving the dentine. Upon clinical examination, this condition appears similar to gemination since the fused teeth have one crown that appears doubled in width. However, unlike gemination, radiographs usually reveal two separate but fused roots with separate pulp chambers. Another way to differentiate fusion from gemination is to count the teeth in the arch. If the fused teeth are counted as two, the total number of teeth will reflect the normal number of teeth in that arch. Like geminated teeth, fused teeth occur more commonly in the anterior portion of the mouth (in less than 1% of the population), and more often in the deciduous
dentition than in the permanent dentition. The mandibular incisor area is affected more often than the maxilla. Fusion is thought to be caused by pressure or force during development of adjacent roots. Many of the reports of fusion involve a supernumerary toothjoining with an adjacent tooth, such as the fusion of a mandibular third and fourth molar, and the fusion of a maxillary lateral incisor and anterior supernumerary tooth. ACCESSORY CUSPS OR TUBERCLES Any tooth may exhibit extra small enamel projections called tubercles, or extra accessory cusps. These enamel projections may result from developmental localized hyperplasia (increase in volume of tissue caused by growth of new cells) or crowded conditions prior to eruption where fusion of a supernumerary tooth may be viewed as an extra cusp. Enamel pearls are small, round nodules of enamel with a tiny core of dentine. They are found most frequently on the distal of third molars and the buccal root furcation of molars. Radiographically enamel pearls appear as small round radiopacities (that is, areas appearing light or white on the exposed film). Being covered with enamel, they prevent the normal connective tissue attachment and consequently may channel disease (periodontal problems) into this region. 1.

Read and translate the text into Russian. CROWNS AND BRIDGES In addition to restoring teeth that are badly decayed or broken, crowns (caps) can improve one's appearance by correcting severely discoloured, chipped or misaligned teeth. To place a crown, the dentist must prepare the tooth reducing it in size, so that a replacement crown can fit over the existing tooth. Impressions of the teeth and surrounding areas are made, and life-size models constructed. Using these models the actual crown is fabricated. Today most crowns are made from alloys. Sometimes these alloys are coated with a layer of porcelain for natural appearance. The patient is given a temporary crown to wear while the permanent one is being constructed. After a «try-in» appointment any necessary changes are made and the crown is put into place. When a single crown is not sufficient to mask the defects and the patient has enough natural teeth remaining, a fixed partial denture (bridge) can be used. For some dental problems, for example, insufficient remaining teeth affected by periodontal disease, a removable partial denture may be recommended. Both fixed and removable partial dentures depend on the existing teeth for their support, and caution must be taken to avoid damage to these supporting teeth. Thorough brushing and flossing, eating a balanced diet, and visiting the dentist regularly will
help to ensure the health of the remaining teeth. Moreover, some precautions are necessary to avoid fracturing the replaced teeth. VOCABULARY EXERCISES Exercise 1.

Exercise 5. Read the text and choose the correct answer to the given questions. PORCELAIN RESTORATIONS Porcelain was first used by the Chinese as long as 1000 years ago, and in more recent times by artists in other countries. The ceramic industry is now a very large one and the use of porcelain for dental purposes is only one of its many applications. The first artificial teeth were made of porcelain in 1815, and the jacket crown was introduced by Land in 1895. Porcelain is composed of kaolin (aluminium silicate) feldspar, and quartz. When heated to the appropriate firing temperature feldspar fuses to glass and this cements together more refractive kaolin and quartz. Small quantities of sodium and potassium carbonate are used as fluxes and the colour is controlled by pigments consisting of various metallic salts. Porcelain has been used for the making of artificial teeth for such a long time that its properties are well known to all dentists. As prepared for dental purposes its colour and translucency can be made to simulate very closely the colour and translucency of natural teeth. Questions: 1. What can porcelain be used for? a) It can be used only for making artificial teeth; b) It can be used for many purposes including dentistry; c) It can be used for many purposes but not in dentistry; 2. When were the first artificial teeth introduced? a) only this century; b)in 1895; c) in 1815. 3. What happens when porcelain is heated to the appropriate firing temperature? a) It burns down completely; b) It breaks; c) The feldspar fuses to glass. 4. What qualities of porcelain are important in dentistry? a) It is expensive;
b) Its colour and translucency; c) Its fragility. 5. How long has porcelain been used in dentistry? a) It is absolutely new, it's not known to dentists; b) It has been used for a long time; c) It is not known. GRAMMAR EXERCISES Exercise 1.

Exercise 5. Translate the following text into Russian in written form using a dictionary. JAWBONE IMPLANTS The method of treatment with a jawbone anchored bridge gives a final result similar to a tooth replacement with bridges attached to the patient's own teeth. The principle of the technique used is that bridge connections of titanium (fixtures) are placed directly in thejawbone. This means that the titanium fixture is built into the bone through the healing ability of the bone tissue (osseointegration). The material titanium is harmless to human tissues and does not cause any rejection reactions. This forms a basis for permanent anchoring function. With this procedure and with careful oral hygiene the jawbone and gums can be kept in a healthy condition. For most persons treatment with a jawbone anchored bridge can be performed by utilising the remainingjawbone. The volume ofjawbone can be roughly estimated by an X-ray examination.

CAST METAL AND PORCELAIN INTRACORONAL RESTORATIONS The modern cast restoration owes its development to an American dentist, Dr. William H. Taggart, who in 1907 described a technique to produce gold castings which fitted prepared teeth with precision. The technique he refined is known as the lost wax process and involves making a wax pattern of the restoration which is then invested in a freshly mixed refractory material contained in a metal casting
ring. When the investment has set, the whole is heated to a high temperature, causing the wax to burn out, leaving a space. Molten metal or glass is forced into mould to form a replica of the original wax pattern. Direct and indirect techniques are two methods by which cast metal restorations can be made. In the direct method the wax is inserted directly into the cavity and the pattern is carved in the mouth and then invested and cast. It is taken to the chairside after polishing but with the margins untouched. Final finishing of the margins is then carried out in the mouth. Where the restoration is simple this technique is quick, accurate and saves both time and expense. However, single cavities can be satisfactory restored with plastic materials and so direct cast restoration is used very little today because it requires two visits by the patient, and is therefore expensive in time. In the indirect method an impression of the cavity and the surrounding area is made in the mouth. From this impression a model of the tooth, a die, is constructed. The wax pattern is formed upon this die, invested, and cast. It is fitted and finished on the die in the laboratory. Thus, only minimal adjustment should be required at the chairside, as the majority of the work has been carried out on accurate models in the optimum conditions of the laboratory. This is the technique of choice for all complex restorations. INDICATIONS FOR RESTORATIONS Direct cast metal inlays can only reasonably be made for very small cavities. The strength of the cast metal has very little advantage and the cost of the procedure is very rarelyjustified. The indirect technique allows a much greater range of preparation design and the most commonly made type of cast metal inlay is used to protect the cusps by covering the occlusal surface. These are called either inlays with cuspal protection or onlays. The second most common indication for indirect inlays is as part of a bridge or other appliance replacing missing teeth. The traditional material for inlays is gold. Pure gold is seldom if ever used as it is a very soft material. Other metals are added to improve the physical properties, and therefore the material used in a traditional «gold» inlay is in fact a gold alloy. In some cases alloys containing 60 per cent or more of gold are still used and these can reasonably be described as gold alloys. However, the high cost of gold has stimulated development and improvements in other alloys and a vast choice is now available to the clinician and technician. Some alloys which are used for
intracoronal restorations contain only 20 per cent or so of gold and so it is misleading to describe these as «gold» alloys. Other alloys contain no gold at all but are based on a combination of other metals. This is why the term «cast metal* is used. Porcelain inlays were used occasionally in the past but with the introduction of composite materials they fell into disuse. However, a new generation of materials and techniques has been developed in the last few years and there has been a resurgence in the interest in porcelain inlays. Porcelain inlays or onlays are more natural in appearance than cast metal inlays and are more abrasion-resistant than composite. Therefore they may be appropriate in the occlusal surfaces of posterior teeth when large restorations are needed and appearance is important. They may be used in the buccal surfaces of visible anterior and posterior teeth when abrasion is a problem. Porcelain veneers may give a very durable and unchanging appearance, and although tooth preparation is necessary, they are more conservative of tooth tissue than a conventional complete crown. Porcelain inlays and veneers are made by one of two completely different techniques. In the first technique, the impression of the tooth is cast in a refractory material which can be heated to very high temperatures without damage. Porcelain powder is mixed to a paste with a liquid and placed into the inlay cavity or onto the labial surface of this refractory model and then fired in a furnace until the particles of porcelain fuse together. The process is repeated a number of times until the restoration is built to the required contour and colour. The second method is to cast an ingot of castable glass into a mould made by the lost wax technique. This glass restoration is then treated in a ceramming furnace which converts the material to a ceramic which is then surface stained and fired to change its appearance.

Exercise 4. Select the facts in the text to support the following statements. 1. An American dentist described a technique to produce gold castings. 2. Direct cast metal inlays can only reasonably be made for very small cavities. 3. Pure gold is seldom if ever used for inlays. Exercise 5. Read and translate into Russian the following text and point out the advantages and disadvantages of cast metal and porcelain restorations. ADVANTAGES AND DISADVANTAGES OF CAST METAL AND PORCELAIN RESTORATIONS Cast metal is stronger in thin sections than amalgam, composite, or glass ionomer cement, and it has a greater ability to resist tensile forces. Thus, it is the material of
choice to protect weakened cusps. It is also ideally suited for extracoronal veneer restorations such as onlays and complete and partial crowns. In contrast, porcelain has high compressive strength but low tensile strength.This means that it is relatively brittle in thin sections, at least until it is bonded to the tooth and supported by it. Cast metal and porcelain are at least as resistant to abrasion as enamel, and there has been some concern that porcelain is more resistant so that if a porcelain restoration is opposed by a natural tooth, the natural tooth may wear down more rapidly. At one time, when the choice of restorative material was amalgam, gold, or silicate, gold was frequently preferred for aesthetic reasons as it was more attractive than amalgam and did not deteriorate like silicate. Also, in many societies it was regarded as a status symbol to have gold visible in the front or to the side of the mouth. Now relatively few patients ask for visible gold restorations. Porcelain, in contrast can have a very natural appearance which is very durable compared with composite and glass ionomer which sometimes discolour or develop stained margins. Cast metal is very versatile material. The indirect technique allows it to be shaped accurately in the laboratory to restore occlusal and axial contours and contact areas. These alloys are almost unchallenged as the materials of choice for bridgework. Cost is the major disadvantage of cast metal and porcelain restorations. The reason for the high cost is the amount of time that they take compared with plastic restorations. There is always a laboratory stage and a minimum of two clinical appointments is necessary. Notes: tensile strength - предел прочности при растяжении brittle - хрупкий, ломкий deteriorate - разрушаться versatile - универсальный Exercise 6. Read the text and answer the questions below. ADULT ORTHODONTICS
Although crowns and bridges may work wonders for some patients, such procedures won't help those with protruding or crowded teeth. Orthodontic treatment is the answer here. Many adults seek care simply because they want a more attractive smile. However, orthodontic problems affect more than just a person's appearance. Crooked, crowded or protruding teeth are harder to clean, and the consequence could be more tooth decay or periodontal disease. If chewing is difficult because teeth are not properly aligned, there is a tendency to choose softer foods, often at the expense of nutrition. Misaligned teeth can also create tension and pain in thejawjoints because of the extra stress placed on chewing muscles. They can cause abnormal wear of teeth and lead to emotional problems due to their effect on speech and unattractive appearance. Questions to be answered: 1. Do crowns and bridges work wonders for patients in all cases? 2. Why do many adults seek orthodontic care? 3. Do orthodontic problems affect only appearance of the patient? 4. What could the consequence of crooked, crowded or protruding teeth be? 5. What teeth can create tension and pain in the jaw joints? 6. What abnormalities do misaligned teeth cause? Exercise 7. Translate the text ^Impressions* into Russian and say which statements given below are true and which are false. Correct the false ones using the sentences from the text. 1. There are three groups of elastomeric impression materials. 2. The occlusal surface of the teeth may be recorded with air bubbles. 3. An interocclusal record is always needed. 4. A special tray is recommended with several elastomeric impression materials. 5. Elastomeric impression materials are not hydrophobic. 6. Careful management of gingival tissues is the key to taking good impressions. 7. A heavier-viscosity material or putty mix is syringed into the preparation and around the tooth. 8. A low-viscosity material is placed in the impression tray.
9. The impression is supported while it sets and then removed from the mouth. 10. There is no need to examine in detail the impression of the prepared tooth. IMPRESSIONS An impression of the cavity and the full arch of teeth is taken in an elastomeric impression material. The dentist may choose to use one of three groups of these materials: the polysulphides, polyethers, or silicones. An impression of the opposing arch is taken, usually in alginate. An important feature of this impression is that the occlusal surface of the teeth should be recorded without air bubbles so that the opposing models can be articulated accurately. An interocclusal record will not be needed where there are sufficient occluding teeth. However, if there is any doubt about the occlusion, a suitable interocclusal record is taken in the intercuspal position. A special tray is recommended with several elastomeric impression materials. The tray supports the material around the teeth. The elastomeric impression materials are hydrophobic and so the prepared tooth surface must be dry. The tooth is isolated with cotton-wool rolls and a saliva ejector is placed in the mouth. Careful management of the gingival tissues is the key to taking good impressions, since any gingival exudate or bleeding will prevent the material from flowing over the prepared tooth surface. The impression materials are mixed thoroughly before taking the impression. The retraction cord is removed and a low-viscosity material is syringed into the preparation and around the tooth. A heavier-viscosity material or putty mix is placed in the impression tray and the tray is seated over the unset low-viscosity material. This helps to adapt it into all the areas of the preparation and into the gingival crevice. The impression is supported while it sets and then removed from the mouth. The impression of the prepared tooth should be examined in detail to check that the entire margin is visible and that there are no voids caused by air bubbles. Notes: impression tray - слепочная ложка bubble - пузырек
saliva ejector - слюноотсос exudate - экссудат syringe - шприц; вводить с помощью шприца putty mix - смесь для слепков gingival crevice - десневая борозда void - пустота, вакуум Exercise 8.

OVERCOMING DENTAL ANXIETY The Canadian Dental Association estimates that over three million Canadians suffer from dental anxiety. These are patients who continually cancel appointments, don't come in for check-ups and delay necessary treatment until they have a much more serious problem. The one million people who never see a dentist, the true dental phobics, are very likely to end up toothless! With modern equipment and techniques, dentistry is now virtually painless. If you are fearful, the first step is to tell us - our goal is to provide you with the best dental care possible and we can't do that if you are not here! These are a few tips to help make your visit to our office worry-free.
Ask questions about procedures that cause you anxiety. If you know and understand what is going to happen, you will have less reason to worry. - eat a light meal before your visit and try not to drink coffee, tea or cola as they stimulate you instead of relaxing you. Eating a rich protein snack like a lean meat sandwich will help stabilise your blood sugar and reduce irritability. - distract yourself in the dental chair by using headphones to listen to the radio or to music you find relaxing. This will muffle noises that may bother you. - establish a signal, such as raising your hand, to let us know you want us to stop a procedure. It will make you feel more in control and give you a chance to ask for more anaesthetic if you feel any discomfort. - the ways you deal with stress outside the dental office will work inside too! Try thinking of pleasant things, deep breathing or relaxing your muscles one by one. - some or all of these techniques may help you feel more at ease but, above all, don't be afraid to ask your doctor for a helping hand. That's what we are here for! It's important that your child's dental experiences are as rosy and pleasant as possible. Frightened child patients grow up to be fearful adult patients, and that usually spells disaster for dental health. That is why, when all other means of relieving anxiety fail, we may recommend premedication. Certain mild drugs eliminate anxiety and fear. Parents should check out any possible allergies. Premedication is the last resort, but sometimes the best choice for putting a fearful mind at ease. Vocabulary to the text: to estimate - оценивать anxiety - тревога, беспокойство, зд. страх, боязнь to cancel - отменять virtually - фактически lean meat - постное мясо irritability - раздражительность to distract - отвлекать to muffle - заглушать (звук) to spell (disaster) - означать, влечь за собой (бедствие)

KIDS' TEETH: COMING OF AGE CAVITY FREE Your children's cavity-counting days can soon be over. Pit and fissure sealants are a simple and effective way to stop the decay that causes cavities, especially in kids' teeth. Here's how they work. Sealants are clear or white plastic coatings we can apply to the chewing surface of the back teeth. The sealant material covers the depressions and grooves on the surface of teeth where cavities are most likely to form. They work best protecting new teeth. That makes them ideal for children. Sealants give those teeth some protective armour through the ages of 7 to 15 when children are most vulnerable to tooth decay. Depending on your child's chewing patterns, the sealants can last from six months to several years. We will check them at every appointment to make sure they are still doing their job properly. Sealants are not designed for areas between the back teeth or for front teeth. And teeth that already have fillings or decay cannot usually be sealed. It takes only a few minutes to apply a sealant, and give your child's teeth years of insurance against decay. There is no drilling or freezing. This is a proven painless technique that can help preserve your child's smile for a lifetime. Text 3. Read and translate the text into Russian. Use a dictionary if necessary. PORCELAIN RESTORATIONS THE PROPERTIES OF PORCELAIN Porcelain has been used for the making of artificial teeth for such a long time that its properties are well known to all dentists. As prepared for dental purposes its
colour and translucency can be made to simulate very closely the colour and translucency of natural teeth. The hardness of porcelain is quite considerable; it varies in different specimens but is generally considered to be about equal to that of feldspar, which stands sixth in Moh's scale of hardness, diamond being in the tenth place and at the top of the scale. The conductivity of porcelain for heat is low, as also is its coefficient of expansion, the latter being about the same as of platinum and half that of gold. It is a very inert substance, being absolutely unaffected by any ordinary reagent, although it is rapidly attacked by hydrofluoric acid. The material is supplied in the form of a fine powder, which when packed into required shape and fired to a proper temperature, is converted into porcelain with which we are all familiar. QUALITIES OF PORCELAIN From the description of the properties of porcelain already given, it would appear to be in many respects the ideal material for dental restorations, particularly in the front of the mouth. It has, however, certain limitations. As in the case of cast gold, the restoration has to be constructed outside the patient's mouth and then cemented into position in the tooth cavity, which must therefore be entirely free from all overhanging margins or undercuts. Thus in some situations when porcelain would be very desirable, it can only be used if a considerable, amount of sound tissue is sacrificed in the preparation of the cavity. This is particularly true in the case of interstitial cavities in anterior teeth (Black's Class III), which usually open proximally, and must be made to withdraw either lingually or labially if porcelain is to be used. HYGIENE AND FREEDOM FROM HARMFUL EFFECTS Porcelain is quite ideal in these respects, notably in the permanence of its glazed surface, in this respect contrasting markedly with the great majority of translucent cement fillings, which, as a rule, have a more or less rough surface. The chief dental uses for porcelain are for: • jacket crowns; • inlays; • additions to artificial teeth.
PORCELAIN JACKET CROWNS A porcelain jacket crown is a crown which is constructed so as to fit over the central portion of a tooth which has previously been reduced to a sort of cone. The cases which usually call for this type of restoration are anterior teeth which are too hypoplastic or carious to be satisfactorily restored by fillings, but which still have sufficient dentine to make a strong cone. The appearance of malformed teeth such as peg-shaped laterals, and occasionally rotating teeth, may often be much improved by means of a jacket crown, though in the latter case the position of the pulp sometimes limits the desired change in form. Occasionally, when a central incisor has been lost at an early age, the lateral may be moved into position and later built up in the form of a central, with very good results. PREPARATION FOR VITAL TEETH In making a preparation for a porcelainjacket crown, care must be taken to leave an adequate amount of dentine for the protection of the pulp. If the tooth is in normal position, the enamel should be entirely removed. The shoulder around the neck of a tooth should be less than 1 mm in width, and only sufficient tissue above should be removed to free the preparation of undercuts and allow for an even thickness of porcelain. Further destruction endangers the pulp and does not add materially to the strength of the porcelain. Another source of danger to the pulp is from heat produced by the friction of cutting. This will be entirely prevented if all cutting is done under a stream of cold water. Occasionally, cold water is also effective in overcoming pain, but more often local anaesthesia is required as well. It is better, however, to delay giving the injection until required, as the anaesthesia obtained will last through the later stages of the preparation when it is most necessary. If the tooth is affected by caries, softened tissue should first be removed and replaced by zinc oxyphosphate cement. The preparation may then be made irrespective of existing caries. PREPARATION FOR PULPLESS TEETH It is sometimes desirable to make a jacket crown instead of a post crown in the case of a pulpless tooth. This is always worthwhile if a jacket crown is also required on one of the adjoining teeth, as the two crowns may then be matched
exactly. It is sometimes also the best method when a crown is being made for a tooth which has had a root resection, as in these cases the root is not always long enough for an adequate post. A slightly shorter post will often be enough to strengthen the core or even to support an artificial core cast in gold. Whenever there is sufficient dentine left, the former method should be adopted, as an entire gold core tends to show through porcelain and spoils its appearance. This difficulty may, however, be overcome to some extent by the use of an opaque porcelain as the first layer in the building of the crown. Text 4. Read and translate the text into Russian. Use a dictionary if necessary. WHAT SHOULD BE DONE ABOUT WISDOM TEETH? There are many good reasons for removing wisdom teeth also known as third molars, there are also some risks and complications that are possible when extracting these teeth and sometimes there are some good reasons for leaving them alone. The decision on a specific course of action must be determined by a wellinformed doctor and patient working together. Consider first the many reasons that people choose to have their third molars extracted. The mouth is often too small for these teeth to fully erupt into a good functional position. This leads to one of several situations: • the teeth remain completely buried in the bone of the upper and lower jaws in which they developed, a condition known as impaction. In case of a fully impacted tooth, it may continue to sit in the bone, surrounded by the normal cyst in which all teeth develop. It may also happen that the normal cyst, later in life, enlarges and may even develop changes in the cells that line the cyst. When such cysts get large enough, they should be removed and examined by a pathologist; • the teeth begin to erupt but are not able to assume their correct upright position. Most commonly the upper third molars will tend to face out towards the cheeks while the lower third molars will lean forward with just a small portion of the crown protruding through the gum. Teeth that are partially erupted lead to two problems. First, they make hygiene of the second molars difficult leading to increased possibility of decay and gum disease (periodontal disease) around these important teeth. Second, the pink flap of gum tissue which partially covers the erupting tooth creates a warm, moist and dark pocket where bacteria which normally live in the
mouth can use the food you eat to flourish, multiply and cause infection known as pericoronitis. It is easy to understand why many people choose to have their wisdom teeth extracted while they are young and healthy and the teeth are surrounded only by a small normal development cyst rather than have to undergo a more extensive surgical procedure later in life when their recovery may not be as easy and their general state of health may not be as good. Finally, some dentists subscribe to the theory that wisdom teeth may push the other teeth in the mouth forward and cause crowding and misalignment. RISKS AND POTENTIAL COMPLICATIONS Some risks and complications are common to all surgical procedures. These are infection, swelling, bleeding and the risk of anaesthetic itself. And there are some risks/complications that are unique to the removal of third molars: • the upper third molars have roots which often are separated from the maxillary sinuses by only a very thin layer of bone. Occasionally, a small communication is established between the sinus and the oral cavity when one of the upper third molars is removed. If this is the case, the normal procedure is for the area to be sutured and closed, appropriate antibiotics and decongestants to be prescribed, and the patient reappointed for follow-up. Most often this results in an uneventful healing period with no further treatment required. Occasionally, the area will heal open rather than closed, in which case an additional small surgical procedure will be required to close the communication. • the lower third molars often have roots that lie very near or even wrapped around the inferior alveolar nerve. This is the nerve that supplies feeling to the lip, teeth and tongue on each side of the mouth. Occasionally, when a lower third molar is removed, that nerve will be bumped or bruised and, if so, a change in sensation may be noted on that side. It is important to understand that this is a sensory nerve and does not affect the ability to move the parts of the oral cavity to which it gives sensation (feeling). In most cases, the nerve heals itself but, because nerves heal slowly, it may take six months to one year before return of normal sensation. Very rarely, the damage to the nerve is permanent. Text 5.

PERIODONTAL DISEASE Periodontal disease affects 90% of all adults and causes 70% of all adult tooth loss. It is a pathological process affecting the periodontium, the tissue that invests and supports the teeth, the gingiva, cementum, periodontal ligament and alveolar and supporting bone. The disease results in inflammation of the supporting tissue of the teeth. This, in turn, results in a progressively destructive change leading to loss of bone and periodontal ligament. If the disease continues to progress without intervention, it results in compromised dentition. What are the signs of periodontal disease? 1. Bleeding gums - your gum should never bleed. 2. Loose and migrating teeth. 3. Halitosis. 4. Swelling and abscess formation. 5. Recession of the gingiva. 6. Vague aching or itching of gums. What are the treatment modalities? Periodontal treatment is designed to eliminate the irritating factors, plaque and calculus. Ideal treatment consists of oral hygiene instruction, supraand subgingival scaling and antibiotic therapy. There is an abundance of evidence gathered over many years by numerous researchers that conventional periodontal treatment including surgery, combined with good microbial plaque control, is successful in arresting most cases of periodontal disease. Today there is a growing debate regarding surgical versus non-surgical treatment of periodontal disease. Non-surgical periodontics involves a conservative approach toward treatment. Basically, it consists of all treatment modalities mentioned, without including surgery except in rare instances. In addition, a phase contrast microscope can be used to monitor the microbial environment. What are the advantages of non-surgical periodontal therapy? 1. The obvious advantage of non-surgical periodontal treatment is that it doesn't require surgery and its attendant discomforts. And since fear is one of the prime
deterrents to periodontal care, reduction in the possibility of pain can bring the benefit of care to larger groups. 2. There is less post-treatment root exposure, which reduces the possibility of temperature sensitivity and root caries. 3. Better aesthetic affects are achieved due to preservation of the gum tissue position as near the tooth crown as possible. 4. Some or all of this treatment may be performed by dental hygienists. 5. Bone tissue is not reduced in an attempt to create normal contour since the technique depends upon bacterial control regardless of tissue deformity. What are the disadvantages of non-surgical therapy? 1. The dentist and periodontist have a greater responsibility to make an accurate diagnosis, explain their findings and treatment regimen, and discuss alternatives. 2. The patient's oral hygiene skills and motivation must be exceptional. 3. The technique is less predictable. 4. The maintenance interval and the instrumentation required at each interval become more critical. Patients on non-surgical maintenance care usually need more anaesthetic and more instrumentation. What does the surgery involve? Periodontal surgery involves elevating the entire soft tissue complex from the underlying alveolar bone by blunt dissection. The alveolar bone is exposed and made accessible for debridement and resection, thus promoting healthy generation. With the roots of the teeth exposed, the periodontist can remove plaque, calculus and stain from the previously unexposed tooth structure. The tissue is repositioned to the height of the alveolar bone and sutured. This eliminates the periodontal pocket which results in improved maintenance. Text 6.

PERIODONTAL DISEASE IN CHILDREN Although periodontal disease is more prevalent in adults, it's important for parents to realise that the disease affects all age groups. About 10 per cent of American children suffer from a virulent form of gum disease known as juvenile periodontitis. This rapidly advancing form of gum disease usually strikes the permanent teeth of otherwise healthy children. The disease often lacks symptoms,
and the gums appear normal. Often, routine dental radiographs reveal bone loss around the teeth, and the disease is then diagnosed. Some research indicates that a plaque-induced gum infection is responsible for the disease; others blame hormonal changes taking place during adolescence that may affect the body's immune system. Recent research suggests the disease may be hereditary and transmitted through the mother's genes. When diagnosed early, juvenile periodontitis can be treated. If neglected, it can spread beyond the initially affected teeth to the remaining teeth and result in loss of permanent teeth. Remember, check your teeth often for signs of gum disease. Practice good oral hygiene at home, and see your dentist regularly for professional cleansing and treatment. Early detection and treatment of periodontal disease can save time and spare painful, costly complications. Text 7. Translate the text into Russian in written form using a dictionary. FOOD'S EFFECT ON TEETH If you are like many people, you probably eat more food than you really need, and the excess may take the form of sugar-rich between-meal snacks such as candy, coffee or tea sweetened with sugar, and sugar-laden soft drinks. Foods containing starches may also cause tooth decay. Starch is present in cereals, bread, vegetables, fruits and processed foods. Researchers are not yet sure of the impact of starchy foods on the teeth. Some believe such foods are harmful if they are eaten frequently throughout the day; others believe they are not harmful unless they also contain sugar or are eaten with foods containing sugar. The decay process begins with plaque - a sticky colourless layer of harmful bacteria constantly forming in the mouth. When you eat foods that contain fermentable carbohydrates (sugars and starches) bacteria in plaque produce acids that can destroy tooth enamel. Each time acid is produced, it attacks the tooth enamel for about 20 minutes. After repeated acid attacks, the tooth enamel may break down and a cavity results. When should I begin cleaning my child's teeth? Even before teeth begin appearing, you should start cleaning the child's mouth to keep food residue and bacteria from damaging newly erupted teeth. After every feeding, wipe the baby's teeth and gums with a damp washcloth or a gauze pad to
remove harmful plaque. You can sit on the sofa with the baby's head in your lap to make sure you can easily see the baby's mouth. If plaque is allowed to build on the baby's teeth, the tooth enamel could become decayed. If the decay is left untreated, the primary teeth may be prematurely lost. Children need all 20 of their primary teeth for proper eating, speaking, and appearance. These teeth also reserve space in the jaw for the permanent teeth that later erupt. A complete set of healthy primary teeth allows proper development of a child's jaw and face. You should begin brushing and flossing your child's teeth after each meal or snack and before bedtime when all the primary teeth have erupted - usually when the child is between 2 and 3 years old. Ask your dentist to recommend a toothbrush for your child. Generally, a brush with soft, end-rounded or polished bristles is recommended because it's less likely to injure the gums. Children often need smaller brushes than those designed for adults. Toothbrushes should be replaced when bristles become bent or frayed, usually every 3 to 4 months. Pre-schoolers often wear out toothbrushes quickly because they brush imperfectly and chew on the brush. Inspect your child's brush often; wornout bristles do not remove plaque effectively. Keep your child's teeth clean from the start. If you notice any signs of decay in the primary teeth, see your dentist promptly. Text 8. Read and translate the text into Russian. DENTAL EDUCATION IN GREAT BRITAIN Curricula and teaching plans of dental education in Great Britain are not uniform and are arranged independently at each university, but in practice they are fairly similar since they are guided by the common recommendations of the General Dental Council. The allocation of the dental course by departments in different universities is not identical. As a rule, there are the following departments: conservative treatment of the teeth (including fixed prostheses), sometimes endodontic departments (treatment of pulpitis and pericementitis), periodontal (periodontal disease and diseases of oral mucosa); prosthetic (all kinds of removable prostheses); and pedodontic including orthodontics, as a rule. The latter is now and then an independent course but is more closely joined to the children's department and is not often linked with prosthetics. In some schools there is a prophylaxis department and an independent radiological department.
The organization of the teaching process varies in different schools. In some, there is a cyclical system when a student works in one clinic for some months, then goes on to another. In others, a parallel system is introduced when a student works the whole term or a year in several clinics. At present great attention is paid (and correspondingly a great number of hours are spent in dental schools) to the teaching of children's dentistry. Gradually children's dentistry is becoming a leading discipline in the training of the dental student. Fees for teaching are paid by students in all universities, in particular, for teaching at dental faculties. There are no government scholarships for students. A proportion of them receive grants from the county education department, and have to work off these grants on completion of their training. Some distinguished students receive university scholarships. On completion of the training young specialists make their own arrangements for their work. A proportion of them, having received county grants, have to work off the grants received after the period of instruction. The majority start work as assistants to dental surgeons in general practice. Some manage to succeed in working up to an independent practice. To begin teaching or to take up a post of a scientific worker it is necessary to work for some years as a house surgeon and registrar in a hospital. It is necessary to spend a particularly long and many-staged training to be permitted to work in a surgical department of a hospital. A school for dental auxiliaries was established in Great Britain only a decade ago. The length of training is two years. The first year consists of general preclinical training with elements of theory and work on the phantom head. Clinical training in the children's dental school takes place in the second year. On completion of their training the students are intended to be sent to dental surgeries of local children's schools, where they will work under the direction and supervision of a dental surgeon, carrying out, apart from procedures of hygiene (removing calculus, teaching the correct hygiene of the oral cavity), treatment of uncomplicated caries and extraction of deciduous teeth under local analgesia. This type of an auxiliary is called a dental hygienist. The most important single aid to a dentist is an efficient chair assistant. The chair assistant should be able to help a dentist in all situations relating to operative procedure; therefore she should have the ability to identify and prepare materials, instruments and equipment for any routine dental procedures. Knowledge of sterilization, medication including anesthesia, tooth form and function, diet, nutrition, oral inflammation and first aid
is important for the chairside assistant. It is also helpful for her to know roentgenographic techniques, office routines and supply management. In general, the teaching in all dental schools is divided into two stages. The quantity of general medical subjects is considerably smaller than in the curriculum of Russian institutes (general pathology, bacteriology, general medicine and some other clinical disciplines). Special subjects such as anatomy and physiology of the oral cavity, pathology of teeth and oral cavity (including regional pathology and anatomy) and (in some schools) dental diagnosis are also included in the curriculum. The study of special clinical disciplines begins in the majority of schools with a rather extensive course in dental mechanics and study of dental materials, and a course of phantom head work in conservative dentistry from four to six months long. Great attention is paid to the technical training of a future dental surgeon. Text 9. Read and translate the text into Russian and answer the questions that follow. THE COLLEGE OF DENTISTRY OF NEW YORK UNIVERSITY Part 1 It is the third oldest and the largest private dental school in the United States. It is administered by the Kiser Dental Centre and is composed of clinics, laboratories, and other teaching facilities contained within several buildings. Since its foundation, New York University has been a private university, operating under a board of trustees and deriving its income from tuition, endowment (пожертвования ) grants from private foundations and government, alumni, corporations and other philantropic sources. Being founded in 1865, the New York College of Dentistry became an integral part of New York University in 1925. With its prestigious background and contemporary perspective, the College of Dentistry, through significant contributions to dental education, research and patient care has extended its influence around the world. A few years ago the College of Dentistry reached a decision to expand its previous three-year curriculum to a four-year curriculum. The curriculum is a synthesis of many areas of knowledge, including biology, physics, biochemistry, medicine, surgery, biomechanics, aesthetics, manual skills and social sciences. In addition to providing the student with a biological and social basis for application of clinical skills, the educational programme focuses on prevention as a much desired goal in
dental practice and research. Advances in the dental sciences and the increasing dental health needs of the public call for an understanding of general health problems and greater cooperation with other health professions. The educational goal is to educate and train clinically competent and sophisticated general practitioners, well-grounded in both basic and clinical sciences, fully prepared to adapt to changes in dental care needs and ready to keep up-to-date with the developing dental knowledge. Part 2 During the first and second years, the course includes both basic sciences and clinical sciences. Students receive instruction in principles of human behaviour, utilization of auxiliary personnel, practice management and other areas relating to the organization of work. They also have courses in nutrition, normal mastication, physical diagnosis and life support and cardiopulmonary resuscitation. Students are also required to choose one of the humanities electives. During the third year extensive didactic instruction is given in endodontics, fixed prosthodontics, occlusion, operative dentistry, oral and maxillofacial surgery, oral diagnosis, orthodontics, pedodontics, periodontics, radiology and removable prosthodontics. At the same time, special attention is being paid to instruction in general and oral medicine, detection and treatment of oral, and facial cancer, cariology. The fourth year is devoted essentially to the Comprehensive Care and Applied Practice Administration Programme which will orient the student preparing him/her for the practice of general dentistry and for providing comprehensive dental care in practice setting. Clinical practice during the first and second years begins with a series of lectures on the dental patient aimed at preparing the student for the duties and responsibilities of everyday practice. The student learns the importance and the role of the dentist as part of the health team. During the second, and continuing into the third and fourth years, each student is assigned patients. Duties begin with examination of the patient and end only when the patient's dental health is restored to the best possible state. The students are responsible for treatment planning, making appointments and providing dental treatment. Research. While the College of Dentistry has long considered its primary mission is teaching, it has placed considerable emphasis on its research activities believing
that an essential part of the education of dental students lies in the understanding of how research contributes to knowledge. Requirements for Admission. All students applying to the New York University College of Dentistry must meet the minimum requirements as follows: 1. Completion of at least three years of study (a minimum 90 hours) in an accredited college or university. 2. The following minimum course requirements must be met: English - 6 semester hours' credit. Biology and physics - 6-8 semester hours' credit. Inorganic chemistry - 8-12 semester hours' credit. Organic chemistry - 6-8 semester hours' credit. Additional courses in comparative anatomy, embryology, histology and electives are recommended. Courses fulfilling the above requirements are offered by the New York University's College of Arts and Science at Washington Square.

FORENSIC DENTISTRY Forensic dentistry is an investigative aspect of dentistry that analyzes dental evidence for human identification. The forensic dentist plays an important role in our justice system. This field of dentistry is divided into forensic odontology and jurisprudence (the science of law). Forensic odontologists study and identify teeth, jaws, prostheses, dental appliances, bite marks, dental injuries, and dental records in the interest ofjustice. Forensic dentistry is one of a number of forensic sciences. Other forensic sciences are listed below: 1. FORENSIC ANTHROPOLOGY examines and interprets skeletal evidence with methods used by archaeologists and with knowledge of human biological variation. This evidence includes bones, teeth, hair, clothing, artifacts, and scene analysis. The examination considers time of death, age, sex, race, body size and weight, individualization, and the cause and manner of death. 2. FORENSIC PATHOLOGY AND BIOLOGY utilizes autopsy, tissue study, and review of medical records in the investigation of injury or death as a result of accident, homicide, or suicide. Legal responsibility usually resides with a medical examiner or coroner. The criteria for death is irreversible cerebral function. The forensic pathologist attempts to determine and report on the (a) cause, (b) manner (homicide, suicide, accident, or unknown), and (c) mechanism of death. 3. CRIMINALISTICS includes fingerprints, ballistics, tool marks (chisel, hammer, etc.), and scene investigation to identify and analyze physical evidence in order to reconstruct the crime and to connect or eliminate suspects and victims. 4. TOXICOLOGY utilizes chemistry, photography, and biology to identify harmful substances within a body. These include medications, poisons, and illegal drugs.
5. FORENSIC PSYCHIATRY examines and testifies about the aspects of legal sanity, human motivation, and possible personality profile. 6. FORENSIC ENGINEERING uses engineers to investigate incidents such as airplane crashes, auto accidents, and structural collapse. 7. QUESTIONED DOCUMENTS TECHNICIANS study and report about printing, typewriting, handwriting, ink, paper, and other features of documents. 8. GENERAL FORENSICS involves other specialists who are qualified to analyze specific evidence such as designers, photographers, and technical experts. They might report, for example, in a case of product liability associated with death or injury. 9. FORENSIC JURISPRUDENCE involves criminal and civil lawyers using the earlier described specialists, reports, and testimony to pursue their case in our system ofjustice.

DENTISTRY AND HUMAN IDENTIFICATION Dentistry often has much to offer in identification because teeth are the most durable parts of the body and dentitions are as individual as fingerprints. Situations involving decompositions and skeletal remains will yield no recognizable facial features or fingerprints. Postmortem (after death) teeth, jaws, prostheses, and appliances can yield a positive identification, given antemortem (before death) records. Erroneous suspected identifications are often eliminated. The benefits of this are such that even with the lack of antemortem records, the effort is worthwhile to aid investigators with information from dental aging, sexing, and estimated socioeconomic grouping derived from restorative materials, attrition patterns, periodontal status, eruption patterns, skeletal features, and serology.
Forensic dental techniques most commonly include collection and preservation of dental and jaw remains, dental radiology, photography, impressions and casts, antemortem and postmortem charting, and the comparison of these records. Features are referred to as Points of Comparison and include (a) the number and identity of teeth, (b) tooth rotation, spacing, and malposition, (c) anomalies, (d) restorations and prostheses or appliances, (e) caries, (f) endodontic treatment, (g) implants and surgical repairs, (h) pathology, (i) bone patterns, and (j) occlusion, erosion, and attrition. DNA can be recovered from periodontal and pulpal tissues, and although DNA analysis has become an important tool in the forensic science armamentaria, it too has limitations including, but not limited to, time and cost. Forensic Dentistry techniques retain a valuable place in the scope of forensic sciences. A well-organized approach results in accurate comparisons and minimizes the chance of error. The examiner should record each feature of the postmortem teeth and jaws and the radiographs on a standardized dental chart. The forensic dentist must carefully organize all evidence so that it is analyzed in a systematic manner using consistent and standardized methods.

BITE MARKS Numerous homicides and attack cases have been solved by bite mark identification, analysis, and comparison. Many bites are severe and leave telltale marks long after an assault. Dental casts and photographs from the suspect are made after obtaining a court-ordered search warrant. These techniques can be useful in solving some child abuse cases in addition to many assaults and homicides. New technologies are coming to use in bite mark analysis to recover saliva DNA, digitalize photographic images, and preserve the unalterable original image on
computers. Details may be highlighted to better see patterns but without physical change to the image. This method has withstood «chain of evidence* requirements. In the past, bite mark analysis had the vulnerability of some subjectivity and the inability to numerically quantify certainties. Today, when DNA can be collected, amplified, and analyzed with the standard accepted modern methods, it is possible to quantify the numerical probability of the association between the biter and the bite mark injury. The forensic dentist must first establish the mark as a human bite mark, then identify, if possible, the teeth involved in the mark. Possibilities may involve missing, extruded, hypoerupted, rotated, tilted, chipped, and anomalous teeth. The dental forensic examiner must also consider the possibility of animal bites, victim self-bites, and marks from foreign objects that might be mistaken for a bite mark. Separate analysis of those markings may be useful to law enforcement agencies by connecting the victim's injuries to a tool or instrument owned by a suspect. Law enforcement agencies are becoming increasingly aware of potential identifications from the dental profession. The notorious mass murderer Ted Bundy (executed January 1989) was positively identified as the responsible person by his bite marks found on the buttocks of one of his young female victims. John Wayne Gacy of Chicago, convicted of 33 counts of murder, became a real test of the vital role forensic dentistry plays in the identification of the involved victims. Only five of the human remains found still had soft tissue, making the identification process a challenge. However, 20 of the 33 known victims were identified through their dental records.

Forensic dentists have made many contributions to the identification of bodies involved in air crashes, mass homicides, structural collapses, floods, and similar disasters. The large volume of specimens and records demands a team approach with excellent organization. The dental team is best organized into antemortem and postmortem teams of two examiners per team. One person handles the specimen and examines the radiographs, while the other person charts findings. The examining pair then reverses roles and checks each other's efforts. Antemortem charting and records must be done separately and stored separately from postmortem evidence during the investigation. An air crash investigation, for example, can result in dozens to hundreds of records and take days to weeks to complete. Long hours of work are involved, as authorities and families seek answers and identifications quickly. There must be organization to avoid errors and oversights from fatigue and to provide the numbers of team members required to complete a project. In mass disasters and in single human identifications, success at the task goes to the undaunted and determined examiner. Knowledge of dental anatomy is a basic. Dental forensic examiners also use close-up photography systems. One particular disaster highlights vividly the unique skills and tremendous value of a forensic dental team in the accurate identification of bodies. Few can ever forget the horror that occurred at 8:30 p.m., 17th July 1996 off East Moriches, New York: the explosion of a 747 airplane, TWA flight 800 bound for Paris, France, with 230 passengers aboard. Within the first 12 hours, a team of 30 dentists, began the painstaking work of identifying the recovered bodies, which were devoid of clothing. Two and a half weeks later, 208 of the 210 recovered bodies and body parts had been positively identified. Identification of 95 was by dental records alone, another 60 by dental records along with medical records (radiographs, MRIs, etc.), medical anomalies, fingerprints, etc. For the first time ever, all relatives were screened for DNA samples to compare with the more than 400 recovered body parts, enabling the return of each to the families for an appropriate resting place. Nuclear DNA samples were extracted from both bone and dental pulps, which was all that remained after the first week. Mitochondrial DNA was also extracted from ground tooth structure, but it is only effective in matching females. One victim was identified by examining DNA on toothbrushes in his home. During toothbrushing, microscopic bits of tissue from the gums and mucosa are scrubbed
off. In all, seven people were identified by DNA alone because no other method was available. Altogether, 61 dentists and 22 auxiliary dental personnel participated in this important forensic project.

COMPOSITE RESINS There are several groups of composite resin materials; although most are toothcoloured, some have been designed for use in anterior teeth, where appearance is most important, while others have been designed for posterior teeth where strength and abrasion resistance are of prime importance. In both cases the material is capable of being attached physically to the enamel by means of the acid-etch technique. Composite is strong in thin section when attached to enamel and so the enamel margins can be bevelled. Composite resins can be attached to dentine by chemical bonding materials or via an intermediate layer of glass ionomer cement. Unfortunately, the bond to dentine is not as strong as the bond to enamel. Since the material shrinks as it sets, there is a danger that it will move away from the dentine towards the enamel in cavities bounded by enamel on one side and dentine on the other, as commonly occurs with cervical cavities. All composites are a mixture of a resin and a filler. Fillers include quartz, fused silicon, and various types of glass including aluminosilicates and borosilicates. Some contain barium oxide to make the material radiopaque. Radiopaque materials must always be chosen for posterior teeth so that the material can be distinguished from dental caries on radiographs. Conventional composites contain 60-80% by weight of quartz or glass particles of sizes ranging from 1 to 50 mm. Particle-size distribution may vary from one composite to another. The more modern materials contain larger quantities of smaller particles, making the material easier to smooth and polish.

Translate the text into Russian in written form using a dictionary. ALLOYS Part 1 GLASS IONOMER CEMENTS Glass ionomer cement is the most recently developed restorative material in general use. It adheres chemically to enamel and dentine. The bond to enamel is stronger than the bond to dentine because enamel is more highly mineralized. However, the chemical bond of glass ionomer to enamel is not as strong as the physical bond of composite to acid-etched enamel. Glass ionomer cements are water based. They are routinely used with conditioning agents (a 10-second application of 10 per cent polyacrylic acid) to remove part of the smear layer. This is important to achieve the optimum adhesive bond. 'Cermet' is a version of glass ionomer cement which contains silver powder. Since the silver particles destroy the tooth-like appearance of the material, it is only used in posterior teeth. Part 2
CAST GOLD AND OTHER ALLOYS The advantage of cast metal is that it is strong in thin sections and can be used to protect weakened tooth structure. This property is the major reason for using cast metal restorations, and cavities are designed so that weakened cusps are protected by a layer of metal. The cavity is prepared in such a way that the restoration (an inlay) is made outside the mouth and then cemented into the cavity. At one time the small gold inlay was a popular restoration and innumerable inlays have served well for many decades. However, they cannot now be regarded as cost-effective by comparison with improved amalgam and other restorative materials and so are seldom made by most dentists. Therefore, the cavity design for small gold inlays is of only limited practical importance, but inlays still have a role to play for larger restorations protecting the tooth.

TREATMENT OF APPROXIMAL CARIES, TRAUMA, DEVELOPMENTAL DISORDERS, AND DISCOLORATION IN ANTERIOR TEETH Part 1 CONDITIONS AFFECTING ANTERIOR TEETH WHICH MAY NEED RESTORATIONS
The conditions affecting anterior teeth are as follows: • smooth surface caries; • approximal caries; • trauma; • developmental disorders; • discoloured teeth; • tooth wear. Approximal caries Enamel caries starts on the approximal surface of anterior teethjust gingival to the contact area. It is less common than pit and fissure caries in the approximal surfaces of posterior teeth. This is because the anterior teeth are more likely to occur when the teeth are crowded and overlapping, because this increases the difficulty in cleaning between them. It is difficult to diagnose early enamel caries at the white spot lesion stage, and so when a patient presents with established caries into dentine in one or more anterior teeth it is possible that the other contact areas have early enamel lesions. For this reason preventive treatment is important, including suitable dietary advice, the use of fluoride supplements (toothpaste, rinses, varnishes) and teaching the patient to use dental floss interproximally. Dentine caries can usually be seen by transilluminating the tooth, either with light reflected from the mouth mirror or by a fibre-optic light. Transillumination is more effective with anterior than posterior teeth because they are thinner. If dentine caries is visible, then it is usually too late for a prevent and observe approach; a restoration is needed. Approximal caries which also involves the incisal edge A neglected carious lesion, or secondary caries around an approximal restoration, may undermine the enamel of the incisal edge to the point where the corner of the incisor breaks away under occlusal forces. Dentine caries balloons out in all directions from its approximal origin, and by the time that it undermines incisal enamel it is often close to, or already affecting, the pulp. The diagnosis of the caries is straightforward, but a vitality test and periapical radiograph are required to assess any pulpal involvement and/or spread of infection into the periapical tissues.
Trauma Accidental damage to teeth has one of the following effects: • fracture of the incisal edge involving enamel only; • fracture involving enamel and dentine; • fracture involving enamel, dentine, and pulp; • root fracture; • cracks in the crown of the tooth without loss of enamel; • no visible damage but damage to the pulp or its blood supply, leading in the long term to pulp necrosis; • partial or complete luxation of the tooth. The restoration of enamel and dentine fractures will be dealt with here. A broken incisal corner involving the incisal edge and parts of the approximal surfaces is treated rather similarly to approximal caries which involves the incisal edge. Developmental disorders Previously, small areas of enamel hypoplasia were considered, and the treatment technique described involved preparation of the tooth and the insertion of a shallow restoration. In this article, larger areas of hypoplasia or discoloration are discussed. The techniques described are also suitable for other malformations including diminutive or peg-shaped teeth. Discolored teeth Several developmental disorders result in discolored teeth. However, a common cause of a single discolored tooth is pulp necrosis, where the breakdown products of hemoglobin discolor the dentine. A bleaching technique to improve the appearance of such teeth can be implemented in such cases. Tooth wear Tooth wear involving the incisal edges is also common. With modern diets, teeth do not wear appreciably at their approximal surfaces, although this did happen with primitive man. Questions to part 1 of the text: 1. How are enamel and dentine carious lesions diagnosed? 2. What can you say about secondary caries?
3. What other conditions affecting anterior teeth are known to you? Part 2 TREATMENT OPTIONS Composite resin materials came into general use in the late 1960s and early 1970s. This produced a revolution in the restoration of anterior teeth, allowing procedures to be undertaken, using the acid-etch retention technique, that were impossible with any previous material. Today, with the added versatility of light-curing materials many anterior teeth which would previously have been treated by crowns or extractions can be restored simply. Uses and limitations of anterior composite materials Provided that the occlusion is favorable, virtually the entire crown of an anterior tooth can be built up with composite, at least as a short-term restoration. This means that the majority of teeth with approximal caries, caries or trauma affecting the incisal edge, and many of the developmental disorders can be treated with composite alone. Tooth wear affecting the incisal edges is less successfully treated with composite since it tends to wear away quickly or break off. If it remains in place, its abrasiveness may increase the rate of wear of the natural opposing teeth. Composite is limited in its use by the fact that it has a relatively low abrasion resistance, although composites vary in this respect, and also it sometimes becomes stained or develops a rough surface. Generally speaking, composites with a higher proportion of resin are prone to staining and those with a higher proportion of coarser particle size filler become rough as the surface wears down. These roof surfaces accumulate both plaque and extrinsic stain. If the occlusion is unfavorable, composite in contact with the opposing teeth will tend to break or lose retention. Composite materials for anterior teeth are available in a variety of shades and in more opaque or more translucent versions. With large restorations it may well be necessary to use more than one shade to produce gradual colour changes across the surface of a tooth to match adjacent teeth. Retention of composite to dentine Anterior composite material should always be retained to the enamel by the acidetch technique, even if the cavity is naturally undercut. This increases the marginal seal and reduces staining at the margins. However, composite is not retentive to dentine. In cavities, where the entire periphery is enamel, this does not matter because retention to enamel is sufficient, but in larger cavities where part of the border is apical to the cement-enamel junction and therefore has no enamel, retention to dentine is necessary. This is achieved in one of two ways:
• by an intermediate layer of glass ionomer cement; • by means of a dentine bonding agent. The traditional method of retention is by means of retentive grooves and/or pins, and these have served for many years. Many dentists routinely used retentive grooves in dentine and a pin to support and retain composite replacing a broken incisal corner. However, even gold-plated pins may produce some discoloration in the composite, and their insertion carries some risk to the pulp. The use of glass ionomer cements or dentine bonding agents has now made these methods unnecessary. Dentine bonding agents have been available for several years but are still being evaluated. Although the clinical results and laboratory tests for the early materials showed them to be effective in retaining composite to dentine surfaces, it became apparent that they were hydrolysing in the long term and reducing the durability of the bond. In addition, polymerization shrinkage of the composite may cause high stress at the bond. Another problem with several of the dentine bonding systems which have been developed over the last few years (and in many cases these have disappeared from the market) was the complexity of the systems, with several bottles of liquid to be applied for different times. Many dentists found this too confusing and timeconsuming to bother with. The newer dentine bonding agents are simpler to use, but do not yet have long-term clinical trial results to support their application. Yet another problem in using dentine bonding agents is that with large restorations it is necessary to use incremental packing, which is fiddly and time-consuming. In contrast, glass ionomer cements are retentive to dentine, release fluoride, and have less polymerization contraction, so that they can be used in bulk to replace all the dentine, leaving space for one increment of composite to replace the enamel. Glass ionomer cements are now available both in their original auto-curing form and as resin-modified glass ionomer cements. This is a developing field, and clinical research in the next few years is bound to influence clinical practice. At present, with large restorations where additional retention to dentine is needed for composite, the preferred approach is the glass ionomer cement-composite layered restoration. Porcelain veneers Porcelain veneers are cemented with composite resin to cover all or part of the labial surface of an anterior tooth. Porcelain has been used for crowns for over a
century and is a very satisfactory restorative dental material in that it maintains its colour and surface gloss and is compatible with soft tissues. Indications for porcelain veneers are where one or a number of anterior teeth are discolored or misshapen in such a way that it is necessary to cover the entire labial surface to disguise the problem and yet the other surfaces are sound. The advantage of porcelain over a composite veneer is that it is more durable in terms of colour and surface gloss, although it is more likely to fracture. The advantage of a porcelain veneer over a crown is that the tooth preparation is more conservative and also, because the palatal surfaces of upper incisor teeth are not prepared, the occlusion is not affected. However, some reduction of the labial surface is usually necessary and so the procedure is not reversible. The restorations are timeconsuming and involve laboratory costs which are often as high per tooth as the cost of a crown. If the tooth being covered is very darkly stained, the thin veneer does not sufficiently disguise the colour and so it has to be made more opaque. For these reasons porcelain veneers have by no means replaced crowns and are unlikely to do so. However, they form a useful addition to the operative dentist's techniques. Other materials and forms of treatment The other two tooth-colored materials which have been used to restore anterior teeth in the past are silicate cement and acrylic resin (polymethyl methacrylate). Neither of these materials is used now for permanent restorations, but many patients still have restorations in one or other of them. Silicate has the advantage of leaching fluoride and so is similar to glass ionomer cement in producing caries resistance. Its main disadvantages were its poor strength, so that it could not be used for incisal edge restorations, its poor solubility, so that the surface became progressively lost in many cases, and its low pH before it set, so that careful precautions had to be taken to avoid pulpal damage. Acrylic used as a direct filling material has a very high coefficient of thermal expansion and so expanded and contracted more than the adjacent tooth tissue, producing rapid marginal leakage. It did not prevent caries, and therefore secondary caries was common. It can readily be identified by its distinctive smell when it is cut in the mouth. Questions to part 2 of the text: 1. What are the treatment options for anterior teeth problems?

Government financial policy may also have an impact on dental practice. 5. The report concluded that oral health services and education of the personnel will need to be radically transformed. 6. It has to be recognized that some individuals with a high susceptibility to disease may be incapable of maintaining a natural dentition during their lifetime. 7. Prevention can be provided in the form of fissure sealant and topical fluoride applications to reduce future caries in these identified high risk groups. 8. When plaque is allowed to accumulate freely there is an acute exudative inflammatory response within 2-4 days in the connective tissue underlying the coronal portion of junctional epithelium. III. INFINITIVE AND INFINITIVE CONSTRUCTIONS Underline the infinitives and indicate their functions. Translate the sentences into Russian. 1. To be useful in predictive case-finding, a test must detect the majority of high risk children and, at the same time identify those at low risk. 2. Clinically, the crevice depth is considered to be the distance to which a blunt probe will penetrate. 3. Rapidly progressing periodontitis is a term used to describe severe generalized periodontitis affecting young adults between 20 and 35 years of age. 4. Many different bacterial species are thought to be of aetiological significance in periodontitis. 5. The objective of oral hygiene education is to produce a change in behaviour which will result in a reduction of plaque accumulation sufficient, if possible, to prevent the initiation and progression of dental caries and periodontal disease, and to make the patient as independent as possible of professional support.
6. A large number of chemical agents have been tested for their ability to reduce plaque accumulation. 7. The UK data indicates not only that more elderly people are likely to have natural teeth in future, but also, that they are likely to have more of them than dentate people in previous generations. 8. If the operator is not confident that all the caries has been reached it is safer to remove the whole of the old restoration. 9. With increasing carious involvement of enamel and dentine, the area of chronic inflammation increases in size but it is believed to remain localized until pulp exposure. 10. Both white and brown spot lesions may have been present in the mouth for some years as it is not inevitable for a carious lesion to progress. IV.

АНГЛИЙСКИЙ АЛФАВИТ
ГРАММАТИЧЕСКИЙ СПРАВОЧНИК I. ПРАВИЛА ЧТЕНИЯ Буквы и звуки Система звуков английского языка отличается от русского тем, что: 1) долгота и краткость гласных влияют на значение слова (напр., английские пары слов cut-cart, pot-port, pick-peak, отличающиеся в произношении лишь долготой звучания гласных, означают совершенно разные по смыслу русские слова: резатъ-тележка, чайникпорт, собирать-вершина); 2) звонкие согласные в конце слов не оглушаются, как в русском языке, по той же причине (напр., bad-bat, dog-dock, что соответствует русским плохойлетучая мышь и собака-верфь); 3) одна и та же буква далеко не всегда соответствует одному и тому же звуку: 26 буквам английского алфавита соответствуют 46 (!) звуков. Одна и та же буква может звучать по-разному в зависимости от соседних букв и типа слога, в то время как буква е в конце слов (непроизносимое, «немое» е), хотя графически и образует слог, не читается вообще. Так, первая буква английского алфавита а имеет не только четыре основных варианта произношения согласно типу слога (cake, can, car, care), но и еще целый ряд вариантов в зависимости от того, какая буква или сочетание букв следует за ней (напр., quantity, can't, и т.п.) 4) Буква -г перед согласными не произносится: form, sport
Необходимо отметить и то, что в произношении как гласных, так и согласных в английском языке имеются многочисленные исключения, поэтому словари, как правило, снабжены транскрипцией,т.е. системой специальных символов, передающих совершенно определенно звучание слов вне зависимости от их буквенного выражения. Это в значительной степени облегчает изучение английского языка как иностранного. Слогоделение Слогоделение в английских словах начинается с последней гласной (согласная во внимание не принимается): la-te, la-ter. Последняя гласная вместе с предшествующей согласной образует слог. Если буква е стоит в
конце слова, и помимо нее в слове есть другие гласные, то она образует графически открытый слог. В графически открытом слоге буква е не читается. Таким образом, в словах late, later по два слога. Примечание. Буква / образует отдельный слог с предшествующей согласной, поэтому в слове table слоговая граница проходит перед b: ta-ble. При удвоении согласных слоговая граница проходит между ними: cutter, иррег. Правила чтения гласных Правила чтения гласных (см. Таблицу ниже) касаются только ударных слогов, которые делятся на четыре типа: I - открытый (оканчивается на гласную) - произношение алфавитное: canine, те, nine, ту, code, mute; II - закрытый (оканчивается на согласную) - произношение краткое, иногда полностью несоответствующее алфавитному: can, men, pin, cyst, cod, gum; III - оканчивающийся на (-г) - произношение долгое, частично или полностью изменяющееся в качестве звучания по сравнению с алфавитным: for, her, fir, myrth, world, purple; IV - оканчивающийся на (г + гласная) - произношение алфавитное с добавлением нейтрального звука [э], который соответствует по звучанию безударной русскойa: care, here, fire, lyre, pure.
Ударение - это выделение слога или слова в речевом потоке. Знак (') ставится перед ударным слогом. Ударение в малосложных словах падает, как правило, на первый слог, в многосложных - на третий от конца. Многосложные слова
могут иметь по два ударения, главное и второстепенное. Второстепенное ударение обычно падает на первый или второй слог, главное фиксированного места не имеет: transplan'tation, res'ponsi 'bility. В английском предложении под ударением стоят обычно значимые слова: существительные, прилагательные, смысловые глаголы, числительные, наречия, вопросительные и указательные местоимения. Безударными обычно бывают служебные слова: артикли, предлоги, союзы, вспомогательные глаголы, личные и притяжательные местоимения. Как и в русском языке, гласные в безударных слогах произносятся ослабленно, нечетко и поэтому, независимо от их буквенного выражения, чаще всего звучат как [э], так называемый нейтральный звук, напоминающий по произношению безударную русскую «а»: комната, нота) или [i]: entrance,['entrans], pencil ['pensil]. Часто безударные гласные не произносятся вообще, напр.: open [oupn], lesson [lesn]. Ударение бывает словесным и фразовым. Словесное ударение выделяет какой-либо слог в слове,фразовое - слово в предложении. Предложения обычно делятся на смысловые группы (синтагмы), слова в которых нельзя отделить, не нарушая смысла. В процессе говорения синтагмы отделяются друг от друга паузами (|). Ударные слоги выделены жирным шрифтом: То become a dentist] one will have to pass entrance examinations! and study for five years||. Ритм и интонация Каждому языку свойственна характерная для него интонация. Ритму английской речи свойственно стремление произносить ударные слоги через более или менее одинаковые промежутки времени, вне зависимости от количества находящихся между ними безударных слогов. Интонация английского предложения влияет на смысл высказывания, т.е. указывает на законченность или незаконченность мысли, придает ей эмоциональную окраску, может выполнять синтаксическую функцию, т.е. придавать высказыванию форму вопроса или утверждения.
1. Для английской интонации характерны два основных тона - восходящий и нисходящий , каждый из которых употребляется в совершенно определенных видах предложений. Первый - в общих вопросах (вопрос ко всему предложению), требующих утвердительного или отрицательного ответа:
Второй - в специальных вопросах (начинаются с вопросительного слова и относятся к одному из членов предложения) и утвердительных предложениях:
2. Первый ударный слогявляется самым высоким по тону, а каждый последующий произносится с постепенным понижением голоса. Последний ударный слог произносится либо с восходящим тоном, либо с нисходящим в зависимости от типа предложения (утверждение, общий/специальный вопрос). 3. В вопросительных предложениях, в которых хотят выяснить, какое из двух предположений является правильным (альтернативный вопрос), в первой части предложения употребляется интонация восходящая, а во второй нисходящая:
II. МОРФОЛОГИЯ Новые слова в английском языке образуются с помощью: 1) словосложения, например, toothache - зубная боль. (Ударение в сложных словах ставится н а первом элементе); 2) аффиксации, т.е. использования суффиксов и приставок, например, суффиксы ег/-ог образуют существительные, обозначающие действующее лицо или профессию: teacher, speaker. Приставка re- обозначает повторяемое действия: rewrite, redo. Ударение на суффиксы и приставки обычно не ставится; 3) конверсии. Конверсия - это совпадение форм слов, относящихся к разным частям речи и потому выполняющих разные функции в
предложении: to work - работать - work - работа; to helpпомогать - help помощь. 4) существительное, стоящее перед другим существительным, выполняет роль определения и переводится на русский язык прилагательным или существительным в родительном падеже: the institute library - институтская библиотека (библиотека института). Основные суффиксы Существительных: -age, -ance/ence, -ancy/ency, -ег/ог, -ian, -ing, -ion, -(i)ty, ist, -ment, -ness, -th, -ure, -y: dosage, independence, emergency, doctor, direction, union, integrity, dentist, establishment, illness, cloth, structure, mobility. Глаголов: -ate, -ize/ise, -y, -en, -fy: indicate, hospitalize, imply, lengthen, intensify. Прилагательных: -able/ible, -al, -ant/ent, -ar, -ary/ory/ery, -ful, -ian, -ic(al), -ish, ive, -less, -ous, -y: capable, dental, important, solar, coronary, helpful, Russian, stomatologic(al), yellowish, intensive, colourless, edentulous, lucky. Числительных: -th, -teen, -ty: fifth, nineteen, eighty. Наречий: -ly: completely, interestingly, fully. III. ГРАММАТИКА Артикль (The Article) 1. Артикль является основным определителем существительного. В английском языке два артикля - неопределенный, a (an), и определенный the. Неопределенный артикль произошел от числительного один (one), поэтому он употребляется с исчисляемыми существительными в единственном числе, когда нужно показать к какой категории предметов или явлений данное существительное относится: a book (одна из многих подобных ей, а не ручка, не стол и т.п.). Определенный артикль употребляется с существительными как единственного, так и множественного числа для выделения предмета или явления из группы таких же предметов или явлений, например: the book (именно та, о которой говорит или подразумевает говорящий и знает собеседник).
2. На артикли обычно не ставится ударение и поэтому они читаются как единое целое с определяемыми ими словами. 3. Артикли не употребляются: - перед именами собственными: Mary, John Brown, Russia, Australia; - перед нарицательными существительными, определяемыми притяжательными илиуказательными местоимениями, названиями наук, болезней и когда перед именами собственными стоит существительное, обозначающее звание: ту doctor, this hospital, Dentistry, caries, Professor Smirnov. Имя существительное (The Noun) Множественное число Множественное число имен существительных образуется следующим образом: 1. Путем прибавления окончания -s к основе, которое после звонких согласных произносится [z]: a canine - canines, а после глухих - [s]: a bookbooks. 2. Если основа оканчивается на звук подобный [s] или [z] (-ss, -sh, -ch, -x), то множественное число образуется добавлением окончания -es, которое произносится с добавлением гласного призвука, а именно: [iz]): a glassglasses, a watch-watches, a dish-dishes, a fox-foxes. 3. Если имя существительное оканчивается на -у, которая стоит после согласной, то у меняется на i,и уже к ней прибавляется окончание es (произносится [iz]): a cavity-cavities. 4. Если существительное оканчивается на -fe, то f меняется на v, к которой прибавляется окончание-es: life-lives. Примечание. Исключение из этого правила составляют а) слова латинского и греческого происхождения, образующие форму множественного числа согласно правилам этих языков: an alveolus-alveoli, a phenomenon-phenomena; б) слова, образующие множественное число путем изменения корневой гласной: a man-men, a woman-women, a foot-feet, a tooth-teeth.

Глагол (The Verb) (общие сведения) Основные формы английского глагола В английском языке существует четыре формы глагола: 1. Основная (base form) - форма инфинитива без частицы to, с помощью которой (путем добавления окончаний, вспомогательных или модальных глаголов) образуются все личные формы английского глагола; 2. Вторая - простое прошедшее время (Past Simple); 3. Третья - причастие прошедшего времени (Past Participle/ Participle II). Эта форма у правильных глаголов по формальному признаку (окончание -ed) совпадает с Past Simple. Единственное отличие - это функция: в предложении Past Simple всегда сказуемое, Past Participle - определение. 4. Четвертая - причастие настоящего времени (Present Participle/ Participle I). Именно в таком порядке эти формы представлены в списках неправильных глаголов в словарях. Личные и неличные формы глагола Глаголы имеют личные и неличные формы. Личные формы выполняют в предложении функциюсказуемого. Они имеют категории лица, числа, времени, залога и делятся на смысловые, вспомогательные, глаголы-связки и модальные глаголы. Неличных форм в английском языке три: инфинитив, причастие и герундий. Они не могут выполнять функцию сказуемого, но функции их в предложении чрезвычайно многообразны. Неличные формы не выражают лица и числа и не имеют обычных глагольных форм времени.
Правильные и неправильные глаголы В английском языке все глаголы делятся на правильные и неправильные в зависимости от способа образования форм прошедшего простого времени (Past Simple) и причастия прошедшего времени (Participle II). Правильными называются глаголы, у которых обе эти формы образуются путем добавления суффикса -ed к основной форме. Неправильными глаголы, образующие эти формы иным способом: изменением корневой гласной, изменением конечных согласных и рядом других способов. Смысловые глаголы, глаголы-связки и вспомогательные глаголы Смысловым называется глагол, который имеет полное лексическое значение. В предложении он выступает в функции сказуемого. Глагол-связка самостоятельного значения не имеет, а служит для связи подлежащего с именной частью. Функцию глагола-связки выполняет главным образом глагол to be - быть, а также глаголы: to become, to do, to turn, to grow в значении стать, становиться, сделаться и ряд других. Вспомогательный глагол - это спрягаемая форма глагола, которая служит для образования сложных форм. Он показывает лицо, число, время, но сам смыслового значения не имеет, а служит для образования сложных форм глагола. Основными вспомогательными глаголами являются глаголы to be, to have, to do, will, should, would.Первые три могут выступать и как самостоятельные смысловые глаголы. Модальные глаголы Модальными называются глаголы, которые выражают не действие, а отношение к нему. Самостоятельно они не употребляются, но в сочетании с инфинитивом выражают возможность действия, его необходимость, вероятность, желательность и т.п. К модальным глаголам относятсяcan, may, must, ought, need. В модальном значении могут употребляться также глаголы shall, should, will, would, а также сочетания с инфинитивом глаголов to have и to be. Залог В английском языке имеется два залога: действительный и страдательный.
Действительный залог показывает, что лицо (или предмет), выраженное подлежащим, само совершает действие. The patient asked the doctor about his disease. Больной спросил врача о своей болезни. Страдательный залог показывает, что лицо (или предмет), выраженное подлежащим, подвергается действию, выраженному сказуемым предложения. The patient was asked about his disease. Больного спросили о его болезни. Времена глагола Система спряжения английского глагола по временам сильно отличается от системы спряжения русского глагола, а именно: каждое из времен настоящее, прошедшее, будущее, в свою очередь, делится еще на 4 подгруппы: 1) Simple (Indefinite) - группа простых (неопределенных) времен; 2) Continuous - группа продолженных времен; 3) Perfect - завершенных и 4) Perfect Continuous - так называемых завершенно-продолженных времен. Глагол to be Глагол to be может выступать в роли как смыслового, так и вспомогательного глагола для образования сложных глагольных форм. Основной его особенностью является то, что для образования вопросительной и отрицательной форм ему не нужен вспомогательный глагол.
Примечание. Для образования кратких ответов повторяется тот же вспомогательный глагол, который есть в вопросе: Are they dentists? - Yes, they are. / No, they агея'г (are not). Is he a dentist? - Yes, he is. / No, he isn't (is not). Were they students? - Yes, they were. / No, they weren't (were not). Will he be a doctor? - Yes, he will. / No, he won't (will not). Случаи употребления глагола to be
Глагол to do 1. То do употребляется в качестве вспомогательного глагола для образования вопросительной и отрицательной форм времен Present и Past Simple и для образования отрицательной формы повелительного наклонения. Do the doctors examine the patients Врачи осматривают every day? больных каждый день? Petrov did not come yesterday. Петров не приходил вчера. Don't smoke so much! He надо курить так много! 2. Как смысловой, глагол to do спрягается по аналогии со всеми английскими глаголами и имеет очень много значений. Спряжение глагола to do (Simple Tense)

3. To do употребляется в утвердительных предложениях для усиления значения смыслового глагола в Present и Past Simple, для чего он ставится перед сказуемым в соответствующей личной форме, в то время как основной глагол употребляется в основной форме (инфинитив без частички to). There are indications that they do know what they are talking about. Есть основания полагать, что они действительно знают о чем говорят. Глагол to have Спряжение глагола to have (Simple Tenses)

Примечание.
В кратком ответе употребляется только вспомогательный глагол в соответствующем времени, лице и числе. Yes, he is. / No he is not (isn't). Yes, we were. / No we were not (weren't). Yes they will. / No they will not (won't). Времена группы Perfect Active Времена группы Perfect употребляются для выражения действия, которое уже свершилось(результат) к определенному моменту в настоящем, прошедшем или будущем времени, и часто употребляется с соответствующими наречиями: just только что, ever когдалибо, already уже, not yetеще не, recently недавно, never никогда, lately в последнее время, недавно, которые ставятся после первого вспомогательного глагола. Примечание. Present Perfect никогда не переводится на русский язык настоящим временем, поскольку передаетдействие, которое было совершенно в прошлом, но имеет связь с настоящим (как результат этого прошлого действия). В противном случае вместо Present Perfect должно быть использовано PastSimple, выражающее действие как факт, не имеющий связи с настоящим: I have left my umbrella behind. Я не захватила зонт (результат: зонта нет - придется идти под дождем). Yesterday I left my umbrella behind and got wet through. Вчера я забыла взять зонт и промокла до нитки (факт, имевший место вчера).

Времена группы Perfect Continuous переводятся на русский язык настоящим, прошедшим или будущим временем, часто с наречием уже Образование Perfect Continuous to have been + Present Participle Вспомогательный глагол to have изменяется по лицам, числам и временам.

Употребление Present вместо Future в условных и временных придаточных предложениях В английских придаточных предложениях времени и условия, относящихся к будущему времени,сказуемое в будущем времени не употребляется: вместо этого глагол-сказуемое употребляется в настоящем времени, хотя на русский язык такое сказуемое переводится будущим временем. Придаточные предложения условия и времени вводятся союзами: if если; when - когда или их эквивалентами (as soon as - как только; after после того, как; before - до того, как; перед тем, как;till, until - пока, пока не и некоторыми другими). If he does not prepare for the examination properly, he will fail. Он не сдаст экзамен, если не будет заниматься как следует. As soon as she comes, we will leave for the country. Как только она придет, мы поедем на дачу. Страдательный залог Страдательный залог глагола показывает, что лицо (или предмет), выраженное подлежащим, не является активным исполнителем действия, выраженного глаголом (сказуемым), а, напротив, само подвергается воздействию. Active Voice Passive Voice I asked the doctor to examine I was asked by the doctor to the patient. examine the patient. Особенностью употребления стадательного залога в английском языке является то, что не только глаголы, принимающие прямое дополнение, но и глаголы с предложным дополнением, могут употребляться в страдательном залоге.

Согласование времен (Sequence of Tenses) ЕСЛИ в главном предложении сказуемое стоит в одной из форм настоящего или будущего времени, то сказуемое в придаточном дополнительном предложении может быть в любом времени, которое требуется по смыслу. Правило согласования времен в английском сложно-подчиненном предложении касается только придаточных дополнительных предложений и выражается в том, что: ЕСЛИ в главном предложении сказуемое стоит в прошедшем времени, то и в придаточном дополнительном предложении сказуемое должно стоять также в одной из форм прошедшеговремени, причем: а) если действие придаточного дополнительного предложения совпадает по времени с действием главного предложения, то в придаточном предложении употребляется Past Simple или Past Continuous. I thougt (that) you were ill. Я думал, что вы больны. I thought that your parents Я думал, что ваши родители lived in Moscow. живут в Москве. I thought that you were examining Я думал, что вы осматриваете
your patients at 9 o'clock. ваших больных в 9 часов. Сравните с русским языком, где два одновременных действия в прошлом выражаютсяпрошедшим временем в главном предложении и настоящим временем в дополнительномпридаточном предложении: I said that I worked here. Я сказал, что работаю здесь. б) если действие придаточного дополнительного предложения предшествовало действию главного предложения, то в придаточном предложении употребляются Past Perfect или Past Perfect Continuous, и оба предложения переводятся прошедшим временем: Не said that he had been seriously ill. Он сказал, что он тяжело болел. Не said that his parents had Онсказал, что его родители lived in Moscow. жили в Москве. в) если действие, выраженное сказуемым придаточного дополнительного предложения, относится к будущему времени по отношению к действию, выраженному сказуемым главного предложения в прошедшем времени, то сказуемое придаточного предложения должно стоять в форме так называемого будущего в прошедшем (Future in the Past) - времени, употребляющемся в английском языке ТОЛЬКО при согласовании времен: I though (that) I would go to the Crimea. I knew (that) theywould be working at the time. He was sure (that) he would have examined all patients by 2 o'clock. Модальные глаголы Модальными называются глаголы, которые самостоятельно (без инфинитива смыслового глагола) не употребляются, так как выражают не действие, а отношение к нему: возможность, вероятность, желательность, необходимость, выполнимость и т.д. К модальным глаголам относятся can, may, must, need, ought, shall, should, will, would. Вместе с инфинитивом смыслового глагола они образуют составное глагольное сказуемое. Модальные глаголы отличаются от других глаголов тем, что: 1. Они не имеют неличных форм (инфинитива, причастия, герундия) и не употребляются в повелительном наклонении. 2. Инфинитив после этих глаголов употребляется без частицы to (за исключением глагола ought).
3. Они не изменяются по лицам и числам и в Present Simple не имеют окончания -s в 3-м лице единственного числа. 4. Глаголы can, may, shall, will имеют формы настоящего и прошедшего времени, а глаголы must, ought, need - только форму настоящего времени. 5. При наличии в сказуемом модального глагола вопросительная форма образуется без помощи вспомогательного глагола to do. Его функцию выполняет модальный глагол, который и ставится перед подлежащим. 6. Отрицательная форма образуется при помощи частицы not, которая ставится после модального глагола, причем с глаголом сап она пишется слитно (cannot). Сап 1. Глагол сап выражает физическую возможность, способность, умение выполнить действие,выраженное инфинитивом. Не can perform any operation. Он может сделать любую операцию. 2. Сап в сочетании с Perfect Infinitive и отрицанием not выражает недопущение возможностисовершения указанного действия и инфинитив перводится на русский язык сказуемым впрошедшем времени. Не can't have said it. He может быть, чтобы он так сказал. May 1. Глагол may в сочетании с Simple Infinitive употребляется для выражения разрешения, возможности (запрещения, невозможности - в отрицательных предложениях), предположения, неуверенности: Уои may walk a little every day. Вы можете (вам разрешается) ходить понемногу каждый день. Не may help you you. Он можетпомочь вам. 2. May в сочетании с Perfect Infinitive употребляется для выражения предположения, относящегося к прошлому, причем инфинитив переводится сказуемым в прошедшем времени: The patient may have learned about the diagnosis from his people. Возможно (может быть), больной узнал о своем диагнозе от родных.
Must 1. Глагол must выражает обязательство, необходимость, долг, приказание, совет: My toothache is getting worse... I'm afraid I must consult a dentist. Зуб болит все сильнее... Боюсь, мне придется (необходимо/нужно) пойти к стоматологу. You must make the analyses immediately. Вы должны (Вам необходимо/надо) срочно сдать анализы. 2. Must может выражать и предположение, причем, если за ним следует простой инфинитив (Simple Infinitive), действие сказуемого относится к настоящему времени (1), если же этот инфинитив перфектный (Perfect Infinitive), то к прошедшему (2): 1. You must be ill: your temperature is very high. Наверное (должно быть), ты болен: у тебя очень высокая температура. 2. I have a sore throat. I must have caught a cold. Уменя болит горло. Должно быть, я простудился. Shall В качестве модального глагола shall употребляется со 2-м и 3-м лицом единственного и множественного числа для выражения обещания, приказания, предостережения, угрозы: You shall finish thejob no matter how much you don't like the idea. Вы закончите работу, как бы вам этого ни не хотелось (приказание, угроза: иначе будет плохо). Не shall teach him a lesson or two, make no mistake. Можете быть уверены, он его проучит, как следует (обещание, предостережение). Should 1. Shoud в качестве модального глагола употребляется со всеми лицами для выраженияморального долга или совета и переводится на русский язык глаголами должен, следует, следовало бы: You should follow the doctor's instructions or you won't get well. Вам следует (Выдолжны) выполнять предписания врача, иначе вы не поправитесь.
2. Should + Simple Infinitive обычно употребляется со всеми лицами в придаточных предложениях: а) дополнительных - после таких глаголов, как to require - требовать, to demand - требовать, to recommend - рекомендовать, to advise советовать. (Сам модальный глагол в таких случаях иногда не употребляется совсем): The consulting surgeon demanded that the patient (should) be operated on at once. Хирург-консультант потребовал, чтобы больного немедленно прооперировали. б)подлежащих, вводимых that и безличными предложениями типа it is (im)possible - (нё)возможно, it is necessary/important - необходимо/важно, it is natural/desirable - естественно/желательно и т.п. На русский язык они переводятся придаточными предложениями, вводимыми созным словомчтобы со сказуемым в сослагательном наклонении, или неопределенной формой глагола: That heshould see an experienced prosthetist is beyond any doubt. Несомненно ему следовало бы показаться опытному протезисту. It is desirable that you should consult another specialist. Вам желательно (Было бы желательно, чтобы вы проконсультировались) проконсультироваться у другого специалиста. в) Should также употребляется в оборотах: I should like to - мне бы хотелось, I should think/consider -я бы считал (рассматривал), I should prefer - я бы предпочел, и т.п. Эти выражения часто встречаются в медицинской литературе и употребляются авторами для того, чтобы сдержанно выразить свое мнение или свою точку зрения. В разговорной речи эти обороты также употребляются говорящими для более мягкого выражения своего мнения. На русский язык они переводятся сказуемым в сослагательном наклонении: I should like to draw your attention to this phenomenon. Мне бы хотелось обратить ваше внимание на это явление. Will В качестве модального этот глагол употребляется со всеми лицами для выражения высокой степени вероятности, желания,
готовности или решимости выполнить действие, выраженное инфинитивом, в некоторых случаях придавая этому действию негативный оттенок: Не will abuse drugs, no matter how much we asked him not to. Он все равно злоупотреблял лекарствами, как мы его ни отговаривали. Would 1. Would в качестве модального употребляется для выражения предположения, желания, совета и переводится на русский язык сказуемым в сослагательном наклонении: It would be most dangerous to delay the operation. Было бы чрезвычайно опасно откладывать операцию. 2. Would (обычно в отрицательной форме) употребляется со всеми лицами для выраженияупорного нежелания совершить действие, обозначенное инфинитивом: The nurse told the patients not to leave the ward, but they wouldn't listen. Медсестра просила больных не выходить из палаты, но они не желали ничего слушать. 3. Would (наряду с should) употребляется в оборотах I would like, we would believe/think/consider, Iwould suggest, и т.п., переводимых на русский как .мне бы хотелось, мы считали бы, я бы предложил и т.п. Заменители модальных глаголов 1. Поскольку глаголы can, may не имеют формы будущего времени, a must - и прошедшего, то вместо них употребляются их заменители-эквиваленты: Эти выражения часто встречаются в медицинской литературе и употребляются авторами для того, чтобы сдержанно выразить свое мнение или свою точку зрения. В разговорной речи эти обороты также употребляются говорящими для более мягкого выражения своего мнения. На русский язык они переводятся сказуемым в сослагательном наклонении: I should like to draw your attention to this phenomenon. Мне бы хотелось обратить ваше внимание на это явление. Will

Поскольку глаголы can, may не имеют формы будущего времени, a must - и прошедшего, то вместо них употребляются их заменители-эквиваленты: can - to be able to; may - to be allowed to; must - to have to. 2. Отрицательная и вопросительная формы с эквивалентами to be able to, to be allowed toобразуются по общему правилу для глагола to be, а для to have to при помощи вспомогательного глагола to do в соответствующем времени, лице и числе.
We don't have to come every day. Did he have to perform the operation? Неличные формы глагола Причастие (The Participle) Причастие - это неличная форма глагола, которая обладает свойствами как глагола, так и прилагательного. В английском предложении причастие может выполнять функцию определения или обстоятельства. В последнем случае оно может переводиться деепричастием. Причастие имеет формы времени и залога.

Простые формы причастия Причастие настоящего времени (Participle Г) Причастие настоящего времени образуется от основной формы глагола при помощи окончания - ing:go - going, speak - speaking. Оно соответствует русскому действительному причастию с суффиксами-ущ (-ющ), -ащ (ящ): идущий (-ая, -ее, -ие), говорящий (-ая, -ее, -ие). Функции Present Participle В предложении Present Participle (Participle I) может выступать в роли определения и обстоятельства. 1. В функции определения к существительному оно может стоять как перед ним, так и после него: The symptoms of stomatitis include infection and inflammation of the mucous membrane of the mouth often involving gingiva, palate, tongue, cheeks and lips. Симптомы стоматита включают инфицирование и воспаление слизистой рта, частораспространяющееся на десны, небо, щеки и губы. 2. В функции обстоятельства Participle I соответствует русскому деепричастию, обычно несовершенного вида и может стоять в начале предложения (перед подлежащим), после сказуемого и в конце предложения. Examining the patient the doctor made the diagnosis of acute pulpitis. Осматривая больного, врач поставил диагноз 'острый пульпит'. On fine days many patients spend time in the hospital garden reading books or walking around. В хорошую погоду многие больные проводят время в больничном саду, читая книги или прогуливаясь.
Если Participle I употребляется в функции обстоятельства времени, перед ним могут стоять союзы when или while. Такие обороты переводятся как придаточным обстоятельственным предложением, так и деепричастным оборотом: When looking at a drop of blood under the microscope one can see what our blood consists of. Рассматривая (Если рассмотреть) каплю крови под микроскопом, можно увидеть ее элементы. 3. Participle I в сочетании с личными формами глагола to be употребляется для образования всех времен Continuous. Причастие прошедшего времени (Participle II) Причастие прошедшего времени (Past Participle), или III форма глагола, у правильных (стандартных) глаголов полностью совпадает со второй формой глагола (Past Simple), поскольку тоже окончивается на -d, -ed (разница выражается только в функции). Для неправильных глаголов определенной формы Past Participle не существует, поэтому необходимо просто заучивать их или консультироваться в словаре. (Список наиболее часто употребляемых неправильных глаголов дан в Приложении 1). На русский язык причастие прошедшего времени переводится полным страдательным причастием, оканчивающимся на: -ный, -мый, -тый: written - написанный; washed - вымытый; studied - изучаемый, изученный. Функции Past Participle В предложении Participle II выступает только в одной функции определения, стоящего перед или после определяемого слова, часто в составе причастного оборота (обороты эти запятыми обычно не выделяются): The examined patient's teeth were found perfectly healthy. Зубы осмотренного больного оказались в полном порядке. The patient examined was sitting in the corridor when he caught my eye. Осмотренный (обследованный) больной сидел в коридоре, когда
я его увидел. The patient examined by the doctor had no complaints. Пациент, обследованный/осмотренный врачом, жалоб не имел. Сложные формы причастия Present Participle Passive Эта форма выражает действие, происходящее одновременно с действием сказуемого и может переводиться как причастным оборотом, так и придаточными предложениями, а то и просто существительным с предлогом: Being anesthetized, the patient suddenly lost consciousness. Во время анестезии (Когда больному проводили анестезию), больной (он) вдруг потерял сознание. Perfect Participle Active Perfect Participle Active выполняет в предложении функцию обстоятельства, выражая действие, предшествовавшее действию сказуемого, и переводится на русский язык деепричастием совершенного вида, придаточным обстоятельственным предложением с глаголом совершенного вида в прошедшем времени или просто существительным с предлогом: Having examined the patient the doctor wrote out a prescription. Осмотрев больного, ... После осмотра больного... После того, как врач осмотрел больного, он выписал рецепт. Самостоятельный причастный оборот (Absolute Nominative Participial Construction) Если в английском предложении в состав причастного оборота входит существительное или местоимение в именительном падеже, которое стоит перед причастием, и эта конструкция отделяется от главного предложения запятой, она называется самостоятельным причастным оборотом. Перевод самостоятельного причастного оборота зависит от места его расположения в предложении.
Если оборот располагается в начале предложения, он переводится на русский язык обстоятельственным придаточным предложением, вводимым союзными словами так как; после того, как; когда; в связи с тем, что и т.п. Если в конце, то присоединяется к нему при помощи союзов причем, и, а, но. Отличительной особенностью абсолютного причастного оборота является то, что причастие в нем никогда не переводится причастием, но нужной по смыслу личной формой глагола (как бы сказуемое), которая полностью согласуется с именем или местоимением, стоящим перед ним (как бы подлежащим), в лице и числе. The boy suffering badly, the doctor gave him an injection to relieve the pain. Поскольку мальчик сильно страдал, врач сделал ему обезболивающий укол. His general condition improved, the temperature still running high. Общее состояние его улучшилось, нотемпература оставалась высокой. The operation having been performed, the patient was taken to the ward. После того, как была сделана операция, больного отвезли в палату. Инфинитив (The Infinitive) Инфинитив - это неличная форма глагола, выражающая действие, но не указывающая на лицо, число, время. Формальным признаком инфинитива обычно является частица to, которая ставится перед ним, но смыслового значения не имеет и в некоторых случаях опускается. В английском языке каждая из четырех групп времен имеет свою форму инфинитива, причем переходные глаголы имеют формы действительного и страдательного залога, а непереходные - только действительного залога. Инфинитив каждой группы выражает относительное время по отношению ко времени сказуемого. Формы инфинитива переходных глаголов Indefinite/Simple
Active to examine
Passive to be examined
Continuous
to be examining
Perfect
to have examined
to have been examined
Perfect Continuous
to have been examining
Инфинитив может выполнять следующие функции в предложении: 1. Подлежащего: То treat neglected diseases is very difficult. Лечить запущенные болезни очень трудно.
2. Именной части составного сказуемого (с глаголом-связкой to be): The doctor's duty is to treatpatients. Долг врача - лечить больных. 3. Части составного гагольного сказуемого: - после модальных глаголов can, may, must, и др. (без частицы to); - после глаголов to have, to be в модальном значении; - после таких глаголов, как to begin - начинать, to continue - продолжать, to want - хотеть, to wish -желать, to plan - планировать, to intend намереваться и т.п., выражающих начало, продолжение или конец действия, или отношение лица, выраженного подлежащим, к действию, выраженному инфинитивом: You must consult a dentist. Вы должны обратиться к стоматологу. Не had to take a course Ему пришлось пройти курс лечеof antibiotics. ния антибиотиками. The surgeon intended to begin Хирург решил (намеревался) the operation at once. оперироватьбезотлагательно. 4. Дополнения: The doctor told the patient Врач сказал больному, чтобы to come again. он пришел на прием еще раз. The sick child wanted to be Больной ребенок просил, чтобы read to. ему почитали. 5. Определения. Инфинитив-определение (Active и Passive) может переводиться различно: - инфинитивом: We have every reason to be proud of our achievements. У нас есть все основания гордиться нашими достижениями. - придаточным определительным предложением или сказуемым (после слов: the first, the last и т.п.): A. Flemming was the first to discover penicillin.
А. Флемминг был первым, кто открыл пенициллин. (А. Флемминг первым открыл пенициллин.) 6. Обстоятельства цели: Перед инфинитивом цели иногда может стоять союз in order (to) или so as (to) чтобы, для того, чтобы: (In order) То keep teeth healthy one must observe oral hygiene rules. Чтобы иметь хорошие зубы, нужно соблюдать правила гигиены полости рта. Инфинитив в функции обстоятельства цели часто переводится существительным с предлогом: То prevent caries one must reduce consumption of sweets in the first place. Для профилактики кариеса, прежде всего, необходимо есть меньше сладкого. Сложное дополнение (The Complex Object) 1. The Complex Object состоит из группы слов, в состав которой входит имя (или местоимение) в косвенном падеже и инфинитив. На русский язык сложное дополнение переводится придаточным дополнительным предложением, причем подлежащим этого придаточного является именная часть Complex Subject, а сказуемым - инфинитив, который переводится личной формой глагола, согласующейся с именной частью сложного подлежащего: инфинитив сложного дополнения НИКОГДА не переводится инфинитивом. При этом простой инфинитив (Simple Infinitive) переводится настоящим временем, перфектный (Perfect Infinitive) - прошедшим, а страдательный (Passive Infinitive) - сказуемым в страдательном залоге. The Complex Object употребляется после глаголов, выражающих а) желание: to want - хотеть; to wish, to desire - желать; should like, would like - хотелось бы; 6)предположение: to think, to believe, to consider думать, считать, полагать; to expect, to suppose - ожидать, предполагать; to find - находить, признавать, считать; в) приказание, просьбу, разрешение: to order, to command - приказывать; to ask - просить; to allow - разрешать и др. г) умственное и физическое восприятие: to see - видеть, to hear - слышать, to feel - чувствовать; to notice - замечать, to observe - наблюдать и др. После этих глаголов инфинитив употребляется безчастицы to.
После глаголов to force, to make в значении заставлять, принуждать инфинитив также употребляется без частицы to: «Не made me go there*, the boy said. - «Он заставил меня пойти туда», сказал мальчик. I know him to be a good specialist. Я знаю, что он - хороший специалист. I expect him to arrive tomorrow. Я полагаю, (что) он приедет завтра. Не felt the pain become less. Он почувствовал, что боль проходит. They heard him call the nurse. Они слышали, что (как) он позвал медсестру. 2. Глагольная часть Complex Object может быть выражена причастием настоящего времени, и тогда оно переводится на русский язык придаточным предложением с союзным словом как: The doctor heard the patient's heart beating irregularly. Врач слышал, как неровно бьется сердце больного. Сложное подлежащее (The Complex Subject) Английское сложное подлежащее (так же, как и сложное дополнение) состоит из двух частей:имени (местоимения) в именительном падеже и инфинитива, между которыми расположено сказуемое. Сказуемое при сложном подлежащем представлено следующими глаголами: 1) в страдательном залоге: to know - знать, to think - думать, to consider считать, to believe -полагать, to expect - ожидать (рассчитыватъ); to say - сказать, to state - заявить (констатировать); to report сообщать; to suppose -предполагать и т.п. 2) в действительном залоге: а) to look - выглядеть; to seem to appear - казаться; to prove, to turn out оказаться; б) to be в сочетании с прилагательными, выражающими разную степень вероятности: (more/less) likely - (более/менее) вероятный; unlikely, not likely - маловероятный; sure, certain - несомненный, безусловный. В русском языке аналога этому грамматическому явлению нет, и потому необходимо знать как переводить эту конструкцию, чтобы она звучала естественно.
Перевод предложения начинается со сказуемого, которое переводится глаголом (часто возвратным) в неопределенно-личной форме, а затем идет придаточное дополнительное предложение, подлежащим которого является именная часть сложного подлежащего, а сказумым - его глагольная часть (инфинитив), который переводится нужной по смыслу личной формой глагола, согласующейся с подлежащим этого придаточного предложения. Не is known/said/believed to be a good doctor. Известно/говорят/полагают, что он хороший врач. The first heart transplant was reported to be performed in the South African Republic. Сообщалось, что первая пересадка сердца проведена в ЮАР Penicillin proved to be ineffective against Gram negative bacteria. Оказалось, что пенициллин неэффективен при инфекциях, вызванных грамотрицательными бактериями. The patient is likely to recover soon. Вероятно, больной скоро поправится. Не is sure to recover soon. Он, несомненно, скоро поправится. Герундий (The Gerund) В современном английском языке герундий - это неличная форма глагола, выражающая название действия, процесса или состояния и обладающая свойствами как глагола, так и существительного. Образуется Gerund так же, как и Present Participle: при помощи окончания -ing, которое добавляется к основной форме глагола: speaking, teaching. Обладая свойствами существительного, герундий может быть в предложении: подлежащим, частью сказуемого, прямым/предложным дополнением, определением и обстоятельством (в этой функции, где герундий можно спутать с причастием настоящего времени, он всегда употребляется с предлогом). Обладая свойствами глагола, герундий может иметь: 1. Прямое дополнение: I like reading books on physiology. 2. Может определяться наречием: The doctor insisted on X-raying the patient immediately 3. Может иметь формы Simple и Perfect и формы действительного и страдательного залогов. Эти формы выражают относительное время по отношению ко времени сказуемого.
Формы герундия Active Passive Indefinite writing being written Perfect having written having been written Отглагольное существительное Окончание -ing имеют не только причастие и герундий, но и отглагольное существительное, которое обладает всеми свойствами существительного: имеет форму множественного числа, употребляется с артиклем, может определяться прилагательными, в предложении может выполнять все функции существительного. После отглагольного существительного часто следует существительное с предлогом of. The reading of books is important for everybody. Чтение книг - полезно для всех. Отглагольное существительное всегда переводится только существительным. IV. СИНТАКСИС Порядок слов в английском предложении Ввиду почти полного отсутствия окончаний, в английском предложении существует строго фиксированный порядок слов: на первом месте стоит подлежащее, на втором - сказуемое, на третьем - дополнение, на четвертом - обстоятельство (обстоятельства времени и места могут стоять перед подлежащим). Но этот порядок слов меняется в зависимости от вида предложения: повествовательного или вопросительного, отрицательного. Порядок слов в утвердительном предложении 0

Общие вопросы (General Questions) Общий вопрос - это вопрос ко всему предложению, который требует в ответ «да» или «нет». Порядок слов в английском вопросительном предложении называется обратным, т.е. изменяется таким образом, что в начале предложения, перед подлежащим, ставится вспомогательный, первый вспомогательный или модальный глагол (см. таблицу выше), затем идет подлежащее, смысловой глагол в основной форме (или остальная часть сказуемого, которое может состоять из нескольких вспомогательных глаголов и соответствующей формы смыслового глагола), а затем все остальные члены предложения. Общий вопрос произносится с повышением голоса (восходящий тон) в конце предложения:
Специальные вопросы (Special Questions)
Специальный вопрос - это вопрос к одному из членов предложения и начинается он с вопросительного слова (who, what, why, when, how many, и т.п.), а дальше идет структура общего вопроса абсолютно без изменений. Произносится специальный вопрос с понижением голоса на последнем ударном слоге (нисходящий тон). Безличные предложения (с формальным it) Если в русском предложении, которое обозначает явления природы, время, расстояние или ощущения, нет подлежащего и оно не подразумевается, то такое предложение называетсябезличным. В английском предложении не может не быть подлежащего, и поэтому в безличных предложениях, где нет субъекта действия, в функции такого (формального) подлежащего употребляется местоимение it, которое на русский язык не переводится. Сказуемое английского безличного предложения обычно состоит из глаголасвязки to be,выражающего функцию времени, и именной части сказуемого, выраженной прилагательным, существительным или числительным. It is getting cold. Холодает. (Становится холодно). It was autumn. Была осень. It'll be warm soon. Скоро будет тепло. Неопределенно-личные предложения Английские неопределенно-личные предложения состоят из формального подлежащего it (one, everybody, they) и согласованного с ним сказуемого. С местоимением it сказуемое всегда употребляется в страдательном залоге. It is known that... Известно, что... One/Everybody knows that... Известно/Каждый знает, что... They know that.... Все знают, что... Выделение членов предложения при помощи усилительной конструкции if is (was/will be) ... that (who/which), it was not until... that Усилительные конструкция типа it is ... that/who/which используется для усиления смысла того, о чем «говорит» многоточие. При переводе смысл того, что находится между it is и that (who/which) выделяется добавлением
слов именно...; только...; только после...; только тогда, когда..., в то время, как сами эти слова не переводятся вообще. It is thanks to scientific research that many dangerous diseases have been eliminated. Именно/Только благодаря науке положен конец многим опасным заболеваниям. It was not until 1628 that blood circulation was first described by W. Harvey. Только в 1628 году появилась первая работа Гарвея о кровообращении.

Некоторые буквы греческого алфавита
Приложение 7 Braces: A Parts List Because your braces are built especially for your mouth, they can shift your teeth with great accuracy. Each part of your braces plays a role in guiding this precise movement.
Приложение 8 Normal Aging of Teeth
Приложение 9 A Normal Adult Mouth In a normal mouth, the upper and lower teeth fit together when you bite down. The teeth move easily against each other during chewing and the mouth feels relaxed, producing a pleasing appearance. But if your teeth don't meet, or if they meet unevenly, you have a bite problem. Chewing ability and your facial appearance may both be affected by one or more common bite problems, such as a crossbite or crowded teeth. A Normal Adult Mouth Bu the late teens or early twenties, the jaw has finished growing, and the size and shape of the mouth is complete. Orthodontist consider an adult mouth "normal" if the teeth fit comfortably into the available space - even if the mouth contains
fillings, crowns, or other dental corrections. A comfortable fit allows the jawbones and joints to work together without pain.
Приложение 10 Common Bite Problems If your teeth protrude or don't meet when you bite down, your problem may be caused the way your teeth fit into the jawbone. Your bad bite (malocclusion) may even be caused by a combination of problems, such as protruding and twisted teeth. If it's only the position of your teeth that is causing your bite problem, braces will improve your condition.
