The role of teeth in the formation of facial beauty

Cognitive interest and importance in the plastic individuals have teeth. As a support for the lips, they even affect the rest of their profiling, tone and vzaimopolozhenie, identifying facial expression and his personality. Baring during the conversation, smiles and laughter, their teeth are signs of actively shaping individuals, adding facial harmony, or destroying it, especially in their absence. Their shape, size and position in the dental row on the edges of the lips and other parts of the face, the proportionality between them, her whole face and its components, matching their shape with the shape of the face and many other things, taken together, form a beautiful face and smile. 


The main purpose of the teeth - chewing food, speech articulation and preservation of facial proportions in its lower third. 
Without going into detail on the structure of the teeth, it should be noted that although they are solid bodies, but not bone structure, as formed from the epithelium. The bulk of the tooth consists of dentin, which has approximately the same composition and strength, as well as normal bone. Dentin is a living tissue, but not so porous as a bone. The crown of the tooth covered with enamel, rich in inorganic salts and strength comparable to quartz. 


The teeth are located in the alveolar bone of jaws and form an arc: the top - in the form of poluellipsa and lower - in the form of a parabola. The form of the dental arch of a curve depends on the type of skull: to dolichocephaly typical elliptical shape of the dental arch, and for brachycephaly - parabolic. In normal occlusion the teeth of the upper jaw overlapping the lower, and the lower edge of the upper incisors corresponds to the upper lip or acting out from under her by 2-3 mm. (Fig. 39).

Vystoyanie upper incisors from the lower lip at rest and, especially, 
with a smile on the large size, give a person individuality, and sometimes peculiar charm (I. Churikova actress, singer A. Makarevich, artists K. Raikin, N. Karachentsev and Brazilian footballer Ronaldo). 


Man - a being omnivorous, so its masticatory apparatus adapted to a mixed chewing. Predators chewing occurs mainly due to vertical motion, the herbivores - from horizontal, and people consistently performs front teeth nibble, and the premolar and molar - rumination. 


The presence or absence of teeth is not only physiological, but also an important aesthetic dimension. It takes into consideration their color, shape, location in the mouth, state, hygienic care, and more. As a result, tooth extraction, partial or complete, begin the slow process of atrophy of the alveoli (decrease in volume). In the complete absence of teeth, body, upper and lower jaw decreases with time on the magnitude of alveolar units, the lower part of the face is not a fixed height and the distance between the nose and the chin is reduced. His lips are thin, drawn inward, his cheeks sunken, deeply marked labial wrinkles and nasolabial folds, and protruding chin and up. A person in such cases becomes a distinctly aged appearance, often not corresponding to the calendar age (Fig. 40).

Tooth color varies from bright white to shades of ivory and yellow. It depends on the individual characteristics of age, of race, from food, smoking, taking drugs ( «tetracycline teeth»), from care and other factors. 


The shape of teeth proportionally depending on the structure of the skull, ethnicity and hereditary factors. Disproportion look inherited from the parents of large teeth on the small face and small teeth on the background of large-sized person. After spending considerable amounts of research, Japanese scientists found dependence of the shape of teeth on the nature of man. Thus, choleric personality type characterized teeth with more acute or right angles, and phlegmatic - more convex surface of the teeth with rounded, sleek surfaces and edges of the transition. Anthropologists and forensic proof of the dependence of the structure, size and shape of teeth of sex. 


Every tooth consists of crown, neck and root. Without describing the morphological structure of the teeth, useful for instructive to review the information on the morphology of the crowns of teeth, especially incisors and canines, as these teeth are in the zone of visibility in the conversation, and different facial expressions. 


With incisors man bites food. Free edge chisel sharp, convex surface of the lip, lingual - concave and at the base of a hillock. Central and lateral incisors of the upper half-arches wider and stronger than the lower, with which they are partially in contact. They are slightly oblique and directed downward, forward and to the middle plane of the face. The central incisor is longer than the lateral limits of 0,5-0,6 mm. The incisors of the lower half-arches of the upper and lower arranged vertically with a certain slant front. The central lower lateral incisor, its cutting edge horizontal; side - a little rounded down to the lateral edge. 


Canine helps incisors tearing his hill in biting and chewing food, but he's bigger and stronger incisors. The crown of the canine has a conical shape, its tearing apart a little bump is shifted to the center, labial surface is convex. Upper canine is wider and longer and lower than him, is closer to the corner of his mouth. Males are larger and sharper teeth, women are less and less sharp. The distance between the middle of the two upper canine teeth corresponds to the width of the nose at rest in men, and the width of the nose during the smiles of women. 


Variants of the ratio of the lower edge of incisors and upper lip lyabiometriey defined and used by dentists, podiatrists in the recovery of the missing front teeth, with the prosthesis in patients with complete absence of teeth. There is a definite relationship: the shorter vertical upper lip, the more stand up from under her upper teeth, while the long lip - the upper teeth may be higher than its level and outcrop only during a smile. Reither leads interesting Photocomposition these relationships (Fig. 41).

Long, white, strong teeth, according to the eastern physiognomists symbolize health and a high level of vitality. People who have straight teeth, usually calm and patient. Protruding teeth, according to Kushi, are a sign of the predominance of yin energy. People with teeth is difficult to adhere to the principles of macrobiotic and balanced diet. People with bowed inward teeth (yang), have great intuitive faith and can easily stick to it. 


Chinese physiognomists believe that the teeth have information about the relationship between spouses, with others, children and closest relatives. Beautiful series of broad, strong and long teeth, in their opinion, shows personal courage of their owner. The small and short teeth, usually occur in strong people. Beautiful, short teeth, like pearls, barely visible during the conversation, give the face an expression of meekness and humility. 
The effect of teeth on the perception of a person said the fact of using various jewelry and change their forms, from the ancient peoples to modern fashionistas Piercing (Fig. 42).

It is interesting to study Swedish scientists, to establish the relationship between memory functions and the presence or absence of teeth in humans. As shown by their study, people who for one reason or another lost some teeth, have less capacity to mentally record what they were doing at any given time, and to determine where and at what point they were. «Teeth are given not only for chewing food, but also to preserve and maintain our brain functions», - said one of the study authors, a university professor, dentist Yang Begdahl. 


Especially harmful to memory, in his opinion, forced, not spontaneous their disposal. Then the person begins to forget quite often two different things and actions. 


Not so long ago, Japanese scientists found the dependence of memory 
the number of teeth, an experiment with monkeys and rats. «Experimented on animals, and colleagues from Japan have convincingly proved: when the doctor removes the tooth, along with it breaks the nerve, leading to the brain», - explained Begdahl. These results surprised even the scientists themselves: Who would have thought that sitting in the dentist chair, every time we lose the pieces of its own memory, and slowly destroying their brains! 


Now the Swedish experts presented the results of research on human beings. The experiment involved one thousand nine hundred sixty-two person aged 35 to 90 years. Scientists have found that when you remove molars in humans, as well as in animals deteriorating memory. Dentists from the University are planning a more detailed study and try to determine how and how to affect human memory and the implantation of dental caries. In addition, they hope the basis of future results answer the question: the lack of any appreciable number of teeth affects the mental faculties of man? Finally, in light of these studies is interesting: not the loss of a tooth depends on the development of age dementia?, And it does not sound with renewed strength and appeal: «Take care of your teeth!» By the way, the answer to the question: «How to save my teeth?», Russia offer humorists: «gather them in a jar with formalin or in a packet of mothballs ...». 


Austrian scientists - andrology and Gynecologists found that the nerves that are appropriate to the roots of the thirty-two teeth, associated with the thirty-two nuclei of the hypothalamus - part of the brain regulating the activity of various organs. During mastication of food teeth are not only as tools, but also serve as a kind of button-stimulants of various human organs. Diseases of a tooth lead to irrational malfunction «his» body associated with this tooth. 


Thus, the two central upper incisors «responsible» for the testes, and the top two sides - for the external genitalia. 
The traditions of European and Asian nations say that God is well disposed to people with a gap between front teeth. And if it passes through a small coin - this is an omen of good luck and wealth.
