Reasons for the formation of dental fluorosis

Dental fluorosis is not only influenced by environmental factors, but also by age factors. For example-year-old, except the third molar teeth, all permanent teeth calcification basically completed, this time even if the move to high fluoride areas of life, it will not have dental fluorosis.

Reasons for the formation of dental fluorosis: Industrial fluorosis, the source of this fluorine metallurgy, fertilizer, or thermal power plants and other industrial production. Processing of mineral raw materials from the release of fluoride. Endemic fluorosis generally refers to high fluoride content in drinking water due to its wide distribution, mainly in rural areas. Pollution-type dental instruments fluorosis areas, the main source of fluorine coal is the residents, the release of too much fluoride, pollute the air and food, causing fluorosis.

Several types of dental fluorosis:

1. Mild dental fluorosis: enamel surface You need scaling it showed a white chalk like the kind of opaque plaques that chalky patches, but there is still hardness and gloss enamel;

2. Moderate dental fluorosis: enamel appears brown or dark brown patches, the most obvious over the front teeth, the enamel is still smooth and hard;

3. Severe dental fluorosis: Most teeth appear brown or even full-mouth dental plaque, while linear, point-like or fissure-like defects, depression has deep dyeing, teeth lose their luster.
