Physiological tooth wear – abrasion of dental hard tissues as a result of direct contact surfaces of antagonistic teeth or adjacent teeth. Contact the opposite surfaces of the teeth occurs when chewing and swallowing food (approximately 1500 times a day). Abrasion of the teeth – is a specific physiological form of abrasion. With this type of abrasion loss of hard tissue of teeth is negligible. With age, the physiological effects of abrasion become more visible. Because of the physiological mobility of the teeth in the area is aproksimalnoy abrasion surfaces adjacent teeth.

The main ways to use local anesthesia in dentistry – injectable and ointment. Anesthetic agent has an impact on various systems, organs, tissues. After absorption in the tissues of anesthetic is distributed throughout the body. In dentistry, local anesthetic injected into the tissues of the maxillofacial area and the oral mucosa, in which there are significant vascular formation, located in the soft tissue and the spongy substance of bone. This can lead to high concentrations of anesthetic in the blood.

The quality of human nutrition, quantity and frequency of meals – a decisive factor in the development of caries. Currently, reduce consumption of natural foods, the emergence of new carriers of energy, improved cooking technology have led to significant changes in the composition of food products and their quality. While the food and may affect the mineralization and structure of hard dental tissue during development, but, so far ns found the relationship between nutritional deficiencies and affected caries.

In physical properties of the permanent filling materials can be divided into three groups: cements, materials for metal seals and polymers. Cements As a material for the permanent seals used silicate cements, silikofosfatnye and ionomer. Silicate Cements. Domestic industry produced Silitsin, Silitsin-2. Foreign analogues: Silikap, Alyumodent, Friteks. The main ingredient of the powder is silicon dioxide. Liquid silicate cement – an aqueous solution of phosphoric acid solution containing additional zinc, aluminum and magnesium phosphate.

Fluorosis is a disease of teeth associated with an excessive flow of fluorine in its increased content in drinking water. The defeat of the hard tissue of teeth – one of the earliest signs of this disease, which manifests itself in breach of the processes of their formation and mineralization. Fluorosis occurs in children during tooth formation consume drinking water containing fluoride at concentrations exceeding 1 mg / liter. The frequency and severity of dental fluorosis depend not only on the concentration of fluoride in the water, but also on socio-hygienic living conditions, determining the nature of power, the amount of water consumption, as well as factors influencing the resistance to fluoride.

Prevention of dental caries and periodontal diseases in pregnant women is twofold: to improve the dental status of women and to implement antenatal prevention of dental caries unborn child. Maternal influences on the development of teeth of the child throughout pregnancy, especially with the 6-7-th week, when starting the process of laying the teeth. Research rudiments of teeth showed that the pathological pregnancy tooth enamel mineralization of the fetus usually slows down and often stops at the initial stage of calcification.

Prevention of pain and emotional stress is one of the most pressing problems in dentistry. The high prevalence and intensity of dental caries and its complications and other dental diseases is forcing almost everyone to go for help to the dentist. Often the medicine was accompanied by the fear of the patient before surgical operations, discomfort and pain. All this can provoke the emergence during the intervention of various complications of a general nature, as well as in further aggravation of chronic and comorbid conditions of patients.

To save resistant to caries tooth enamel requires an effective means of influencing it. In the crystal lattice of biological apatites are vacancies and defects – absence of an atom or columns of atoms, called dislocations. Sometimes in the crystal there is only one column of atoms without any of the crystal lattice, which is the reason for the rapid penetration of acids along the axis of the crystal – a speed of 500 angstroms / sec. For the crystallization processes in enamel is important and its organic matrix, which includes the calcium-binding protein that is necessary for nucleation and crystal growth regulation as well as variations of concentration of fluoride ions in the fluid surrounding enamel.

Restoring normal function of muscles is achieved through special exercises. The principle of prevention ZCHA with mio-exercises involves training the under-developed muscles, which allows you to normalize the function of muscle antagonists and synergist. Gymnastic exercises for the muscles surrounding the tooth rows, as a method of orthodontic prophylaxis were offered Rogers in 1917 Exercises chosen taking into account the child's age. They should not be too difficult to understand, it is desirable to convert them into the game.

To implement the main tasks of prevention ZCHA must be able to establish an unambiguous link between the morphological features and functional features of physiological bite, to be able to relate restbite with various stages of its formation. Bite – the ratio of dentition (teeth) when closing with the largest number of contacts. Consequently, the norm – the notion of the correct position of teeth, the form of dentition and jaws, respectively, the ratio of mean bite and the period of its development until the formation of permanent dentition.

Pericoronitis One of the diseases that most often arise because of the wisdom teeth, is called "Pericoronitis. Pericoronitis – an infection that occurred in the tissue surrounding the wisdom tooth, which was unable to fully "break" through the gum tissue and occupy the normal position (such wisdom teeth are called "not fully carved) Signs perikoronita – sensitivity and swelling of the gums surrounding the wisdom tooth. May arise and severe pain, halitosis, or in the mouth appears an unpleasant taste Caries wisdom tooth The cavities are formed in the teeth due to the fact that on the surface of the tooth for a long time accumulated plaque.

In modern dentistry are increasingly using microprosthetics. Microprosthetics essence of technology is the use of tabs that are using zhidkotekuchih filling materials are fixed in the cavity of the tooth or on its surface. The tabs or plates composed of various ceramic compositions are made in the dental laboratory, which is an advantage compared with conventional technology seals. With a more thorough treatment of the material and polymerization of the restoration of the tooth is more durable and looks much more aesthetic than the usual filling of the tooth.

Ozone therapy in dentistry can do incredible – get rid of the drill. Of course, this is only possible when the patient is regularly visited by his doctor because the doctor can catch the development of caries at the initial phase of the project. If the enamel and dentin is severely damaged, and the hole and the depth of detritus, which accumulate germs cavities, comparable in relative size to the Mariana Trench, there is virtually no machining is necessary. Nevertheless, ozone therapy tooth decay – is a reality, which is actively used by anyone who hated the sound of a drill.

Many internal organs receive both sympathetic and parasympathetic innervation. The influence of these two departments is often antagonistic nature. In physiological conditions, the activities of internal organs depends on the prevalence of certain influences. With the predominance of parasympathetic tone of the evolving state of vagotonia, the sympathetic part sympathicotonia. For example, stimulation of sympathetic nerves leads to increased frequency of heart contractions, and stimulation of parasympathetic fibers has the opposite effect of decrease in heart rate.
