Išsamus aprašymas

Alternative names: dental cavities; tooth decay.
Definition: A disease of the teeth resulting in damage to tooth structure.
Dental caries is one of the most prevalent disorders afflicting mankind, second only to common cold. It usually occurs in children and young adults. Dental caries is a relatively recent in human history. Dental caries remain a relatively rare disease in some areas of the world. In Europe, North and South America, virtually every person is attacked at some time during his life.
Tooth decay seems to be a disease of civilization possibly associated with refined foods. A lack of dental cleanliness is also closely associated with tooth decay.
There are three main factors that be simultaneously for the condition to occur:
●microbial dental plaque;
●teeth susceptible to caries;
●diet that provides a frequent supply of fermentable carbohydrate
Microbial dental plaque is a colorless, bacteria laden film that forms daily on the teeth. The bacteria convert all foods-especially sugar starch-into acids. The onset of carries is early in susceptible populations. Decay occurs where bacteria and foods adhere to the surface of the teeth. Many individuals with high caries susceptibility speak of inheriting “soft teeth” or that the resistance to tooth decay is strongly influenced by genetic variation in tooth composition.
Prevention. Oral hygiene is the primary prevention against dental caries. This consists of personal care and professional care. The use of dental sealants is a good means of cavity prevention. Sealants are thin plastic-like coatings applied to the chewing surfaces of the molars.
Symptoms and Signs: ● toothache; ● cavities. Most dental caries are discovered in the early stages during routine checkups. The surface of the tooth may be soft, pain may not be present until advanced stages of tooth decay and dental X-ray may show some cavities before they are visible.
Treatment. Destroyed tooth structure does not regenerate. The progression of dental caries can be stopped by treatment. In filling teeth, the decayed material is removed by drilling and replaced with a restorative material such as silver alloy, gold, porcelain, or composite.
Treatment often preserves the tooth.
