Dental caries is the most common disease of the teeth and is one of the most widespread diseases in humans. The percentage of widespread of dental caries is particularly significant in less cultured people, giving rise to the claim that the creation and distribution of dental caries is closely related to culture and its influence.
The biggest reason for dental caries is dental plaque bacteria (poor oral hygiene) which act on the metabolism of carbohydrates (the remaining parts of food in the mouth) and lead to acid formation. A drop in pH values, and this results in initiating a chain of events that occur on the surface of the tooth. Important factor is diffusion of calcium and phosphorus ions from the enamel. The process is known as demineralization of enamel and is an initial step in dental caries. It is interesting that this process may be reversible, if it comes to that, the pH rises again. Dental caries is therefore a dynamic process that is characterized by episodes of demineralization and remineralization which occur during a period of time. If you are late, dominated destruction will lead to degradation of mineral components, which leads to the formation of cavities. Dental caries begins on the surface of the teeth and looks like a white dot. This appearance is caused by the prisms of the enamel, which is built and stripped of calcium and phosphorus ions. Dental caries is followed by the invasion of bacteria on previously performed demineralization. Once they get to the enamel dentine border, it comes to a lateral expansion which undermined enamel and complicates treatment. Tooth defend himself in a manner that creates a secondary dentine to prevent penetration of bacteria to the tooth pulp.
Under favorable conditions, lesions may become inactive and even pull-regress. Clinical stopped dental caries have hard or leathery consistency and usually have a darker color than yellowish active caries. Stopped enamel caries may be dark gray.
