What is caries?



  What is caries? Caries - a deterioration of tooth enamel and tooth due to subsidence in the teeth of food residues, which breed bacteria and begin to destroy the tooth.

First tooth looks like a place on the tooth, slightly different in color from the rest of the tooth surface. If time does not start treatment, place of caries becomes darker and gradually turns into a hole, which can be cured only by appointment with a dentist.

  What is caries?
Word of caries in the exact translation means "putrefaction". This is the term used showed as an inflammatory disease of the bone marrow material (osteomyelitis). Without serious etiological, morphological and clinical similarities of processes that term came to be called the disease of hard tissues of the tooth, the outward manifestation of which is to destroy the enamel and dentin of the tooth.
In the occurrence of a carious lesion teeth are particularly important factors of internal environment (the state of the protective systems of the body, digestive system, nutrition, etc.). Consequently, caries is regarded as a manifestation of general disease organism from tissue damage teeth, so more correctly called caries "carious disease."

  Why is dental caries?
There are currently over 400 theories of dental caries. One recent concept is that as a result of failure of oral hygiene (not regular and proper maintenance, cleaning teeth) on the enamel appears soft plaque in places where it is not removed during chewing (side surfaces of the teeth, deepening the chewing surfaces) . This plaque is closely associated with the surface of the tooth and serves as a place of concentration of various bacteria and fungi. Among the members of the plaque bacteria, half are streptococci. The inclusion of plaque mineral salts contributes to its compactness. This education is called dental plaque. Found that localized in the plaque bacteria produce lactic acid, which can cause demineralization of enamel, which gives rise to the caries process. Prominently in the structure of plaque is given dextran - polysaccharide produced by bacterial plaque. Dextran is formed streptococci from sucrose. Apparently, so use a large amount of sugar contributes to tooth decay.

  Clinical forms of caries
Allocate 4 forms carious disease, each of which essentially reflects the degree of destruction of hard tooth tissues: carious spot, surface caries, middle and deep.

  Do all people develop caries?
Step kariesogennyh bacteria in dental plaque, not everyone appears equally. For most people, resistance to caries is weak, at others it is high enough. Stability of teeth to caries is associated with the condition of the protective systems of the organism, concomitant diseases. Found that in people with weakened immune caries develop more actively. In children suffering from exudative diathesis, rickets caries develops in 1.5-2 times more often.
An important role played by the composition and properties of saliva. Found that in people prone to tooth decay, saliva is more viscous and it changed the ratio of the content of mineral salts.

  To determine the risk of caries has developed various tests.
They are based on:
 calculating the concentration of bacteria in the saliva Lactohacilli (Dentoculf LB)
 Mutant Streptococci (Dentoculi SM) test on saliva buffer capacity (Dentobuff)
 tests based on socio-economic factors
 existing pattern of prevalence of caries and clinical opinion dentist.

  Microbiology tooth 11,111,117.
It is shown that dental caries does not develop in animals whose bodies are devoid of bacteria, even in cases where these animals are kept on kariesogennoy diet. The cause of dental caries are not individual species of bacteria, and acid - waste product of a number of microorganisms (the hypothesis of nonspecific bacterial plaque).

 [b] How to avoid caries disease?

To prevent dental caries, observe the correct diet.
The enemy of your teeth is a sweet foods and sugar, as well as other foods containing a high percentage of carbohydrates.
The fact is that the sticky, sweet food remains stronger than settle on the teeth, and get rid of them, simply wash your mouth, it is impossible. On the sweet and bacteria accumulate and multiply more rapidly.
If you want as long as possible to maintain health and whiteness of their teeth, turn on the diet of food that is rich in protein, phosphorus and calcium - these substances contribute to the strengthening of teeth.
