Dental fluorosis, also known as patchy enamel, is a special type of enamel hypoplasia caused by excessive fluoride intake during tooth development. Clinical manifestations mainly include stained enamel patches and defects.
Dental fluorosis is a prominent symptom of regional chronic fluorosis.
Regional chronic fluorosis mainly involves developing teeth and bones.
Dental fluorosis has been reported in countries all over the world.
There are many endemic areas of dental fluorosis in China. Chronic fluorosis has been reported in almost every province, and the disease is relatively serious in mountainous areas and coastal areas.
1. Dietary habits and the absorption of fluoride in food depend on the concentration of inorganic fluoride in food and the content of calcium.
If calcium compounds are added, the absorption of fluorine is significantly reduced.
Animal experiments have proved that sufficient vitamin A, D and appropriate amount of calcium and phosphorus can reduce the damage of fluorine to the body.
2, climatic conditions, high temperature areas drinking water consumption is high, intake of fluorine is also increased.
3, individual differences, individual sensitivity to fluoride can explain the severity of dental fluorosis patients in high fluoride areas.
4, fluorine also comes from the pollution of the environment, that is, from metallurgy, chemical fertilizer or thermal power plant and other industrial production, with high fluoride content of fuel (stone coal), fluoride in the air exceeds the standard, can be inhaled into the body, increasing the total intake of fluorine.
In addition, whether dental fluorosis can occur depends on how much fluoride enters the body.
Fluoride mainly damages the ameloblasts of tooth embryos during enamel development. Therefore, excessive fluoride can only occur when it enters the body during tooth development and mineralization.
Dental fluorosis can result from prolonged residence in endemic areas with high levels of fluoride in drinking water before the age of 6 or 7.
Disease prevention and control 1, improve water sources, fluoride intake.
2, light or color without defect can be used bleaching decolorization method.
3, severe defects of the affected teeth can be directly composite resin veneer, porcelain veneer or nail repair methods.
