Dental caries is not genetic?

Foreign scholars have been a lot of research data on dental caries will not hereditary. In animal experiments, nurturing sensitive to caries and caries-immune mice. In humans, through the observation of familial, double Born caries risk of the situation, has been confirmed in the same family, parents and children's dental caries incidence has a significant relationship. If the parents of caries, dental caries is also more of their children. If the parents of dental caries incidence is low, the incidence of dental caries of their children. These findings, dental caries has a genetic predisposition. The results also proved that the mouth in all aspects of hereditary enamel structure, tooth morphology, size and dentition, arch form, tooth occlusal surface fissure depth, content and buffering capacity of saliva, as well as crown convex self-cleaning function, caries.

1. Enamel calcification, anti-caries ability; the contrary, the anti-caries is low.

2. Tooth morphology; size and crown and dental caries: tooth morphology is not good or crown the role of the self-cleaning; food debris and plaque is easy to attach, easy to cause dental caries.

3. The depth of the teeth, the occlusal surface fissures hereditary tooth dental equipment occlusal surface of dental caries predilection sites. Shallow fissures, food residue is not easy attachment can also be easily cleared; the plaque is not easy to form caries less. If to crack Goushen, embedded in the food and bacteria accumulate, the plaque the crack Goushen Ministry is not easy to remove, the gradual formation of caries.

4. The relationship between saliva and dental caries, a lot of information reported, the amount of saliva, saliva viscosity and dental caries incidence is closely related. The more obvious examples of saliva and dental caries relationship are this: If the salivary glands to Missing teeth repair radiation therapy, saliva reduced viscosity increased oral dental caries soon.
