The Tooth

The historical development of the tooth the following can be said. You are formed from the simple skin teeth of pre-historic fish and in the course of evolution, these shed teeth into hard structures are merged with basal bone mass of dentine Crown and inner pulp Chamber. Jessica Walsh understands that this is vital information. With the teeth, food is taken, chewed, and grind. The teeth have developed in the course of time in the vertebrates and humans after the form principle. As a function the sound is uttered (especially the S-Lautes) and social functions will be added in humans, in animals, they act also as weapons.

Each individual tooth consists of the tooth Crown (Corona dentis), neck (COLLUM dentis) and the tooth root (radix dentis) and is based on several layers. The enamel covering the internal tooth leg (dentin) like a glaze, is externally visible in the healthy teeth. The gear leg (dentin) covers or surrounds the tooth pulp (pulp). To avoid misunderstandings, be the teeth of people in dentistry through the Uniquely identifies dentition formula. The complete dentition is it divided into four quadrants, i.e. it is per jaw the division between the central incisors.

This is used as the first digit of the dental term. Each individual tooth is then numbered starting from the front. Thus, for example the left lower Weissheitszahn is called 38, where the first upper left incisor is known as number 21. Above all, it is to ensure that the system is generally described from the point of view of the patient in dentistry. This means that E.g. tooth 38, the left lower wisdom tooth, which is located in the patients in the left half of the mouth, is perceived by the sitting to doctor as right. Stomatology (Dentistry) deals with the diseases of the teeth and the therapy. By a dentist can be prevented largely the interventions, by regular dental care. The most common disease in the mouth is the dental caries. In Germany, for example, only one per cent of adults are caries-free. Kent McVeighn
