Dental caries

Cavities, also known as caries or cavities, illness, changes in bacterial carbohydrates processes, such as sugar in the diet on their teeth to acid demineralized tooth structure (enamel, dentine and cement) on the left. If the demineralization exceeds remineralization of saliva and others, such as calcium, these tissues are gradually reduced, producing tooth decay (cavities, holes in teeth). Two groups of bacteria responsible for the initiation of tooth decay: Streptococcus mutans and Lactobacillus. If untreated, illness, pain, tooth loss and infection.Today lead, dental caries remains one of the most common diseases worldwide. Cariology, the study of dental caries.Presentation of caries varies greatly, however, risk factors and stages of development are similar. At first this may seem a small section of the Cretaceous, which may eventually grow into a large cavitation. Sometimes tooth decay can be used directly visible, but other methods such as X-rays to detect less conspicuous area of ​​the teeth and to assess the extent of destruction. Laser to detect tooth decay without the emission and to ensure the collection will now be used for the detection of interproximal caries (between teeth). Disclosure decisions are also available, which are used during dental prosthesis to minimize the chance of recurrence.Tooth decay is caused by certain types of acid-bacteria, damage in the presence of fermentable carbohydrates such as sucrose, fructose and mineral composition of the teeth caused glucose.The sensitive to high acidity in the production of lactic acid. In particular, the tooth (which is primarily mineral in content) in a constant state of back and forth demineralization and remineralization between the tooth and surrounding saliva. For people who have very little saliva, there are also remineralizing gel, especially by radiation therapy, which can destroy the salivary glands. These patients are particularly susceptible to tooth decay. If the pH value on the surface of the tooth drops below 5.5, demineralization proceeds faster than remineralization (ie there is a net loss of mineral structure on the surface of the tooth). Most foods are acidic in this region and without remineralization, this leads to the subsequent decay. Destroyed depending on the size of the tooth, the various treatments applied to the teeth, to restore the proper form, function and aesthetics, but there is no known method to a large number of dental hard tissue regeneration, stem cell research as a possible answer involves [Change]. Instead, dental health organizations advocate preventative and prophylactic measures such as regular oral hygiene and dietary changes to prevent tooth decay
