CARIES - pathological process of infecting the tooth after its eruption, accompanied by demineralization of hard tissue that subsequently leads to the formation of a defect in the form of the cavity.
Currently, dental caries is among the most common diseases. This is due primarily to social factors: working and living conditions of people, the nature of their diet and environmental changes, lack of fluoride in drinking water sources, poor oral hygiene and other reasons ..
The high prevalence and intensity of caries requires a broad prevention of this pathology.
Preventive protivokarioznye activities based on knowledge of the laws of the etiology and pathogenesis of dental caries. It is known that the occurrence of dental caries due to the interaction of general and local factors. The factors include the overall impact of inferiority diet and drinking water, various functional disorders of organs and systems, as well as the impact of extreme conditions. Local factors: plaque (its composition, quantity), breach of oral fluid and its properties, the presence of the teeth starchy food residues. Important role in the etiology of dental caries assign resistant fabrics, ie their full structure and chemical composition.
The clinic used topographic classification of caries in the light of the depth of destruction of dental hard tissues. There are spots in the stage of caries (initial caries), superficial, intermediate and deep.
Initial caries, or cavities in the stage of sunspots - is a defeat of enamel, in which the surface layer of it remains intact. Carious spot can be chalky or pigmented. On the surface caries defect is formed within the tissues of the tooth enamel caries with an average defect occurs that goes beyond the enamel-dentinal compounds, with deep caries to a significant degradation of the dentin thickness of cavities, the bottom of which is separated from the cavity, only a thin layer of dentin.
Treatment of initial stages of caries in the stage of spots, especially chalk, exercise through remineralization. If a tooth cavity make it filling.
