Dental caries will not be genetic

With regard to dental caries will not be genetic, foreign scholars have a lot of research. In animal experiments, the training of dental caries and caries-sensitive immune mice species. In humans, by observing the family, was born two-caries, has been confirmed in the same family, parents and children of the incidence of dental caries a significant relationship. If the parents of dental caries, dental caries of their children also. If parents with low incidence of dental caries, and their children, the incidence of dental caries are also low. These results show that the genetic tendency to have dental caries. The study also shows that all aspects of the oral cavity are hereditary, such as the enamel structure of the tooth shape, size and dentition, dental arch shape, teeth biting surface-groove depth, the content of saliva and oral cushion, as well as crown Crown of the self-cleaning effect, and so on, and they are related to the incidence of dental caries.

(1) enamel calcification, high-capacity anti-caries; On the other hand, anti-caries power.

(2) dental patterns; and the size of the crown and the crown of the tooth decay: If the bad form of dental crown or crown is not good, poor self-cleaning effect; food debris and plaque attached easily, easily lead to dental caries .

(3) teeth bite-groove surface has inherited depth, and teeth biting surface caries is a good site. Shallow-trench, food residue is not easy attachment can also be easily removed; plaque formation is not easy, less caries. If the depth of the crack, embedded in the food and bacteria accumulate, the Department of Goushen crack is not easy to remove the plaque, caries shape.

(4) oral saliva and the relationship between dental caries, it was reported that a lot of information, saliva, saliva and the viscosity is closely related to the incidence of dental caries. Of the more obvious examples to illustrate the relationship between saliva and dental caries is: If the salivary gland by radiotherapy, to reduce saliva, increased viscosity, oral caries soon.

In recent years, it was found: in developing countries suffer from dental caries rate, the rate of caries in developed countries declined. According to the above, genetic factors in whether caries play a major role, is doubtful
