Dental fluorosis

Overview dental fluorosis is enamel during the development of excessive fluoride intake derived from a special type of enamel hypoplasia. Dental fluorosis with regional, chronic fluorosis disease and the most common early symptoms of highlights. Dental fluorosis also known as tooth enamel plaque. Cause pathogenesis mineralization in the teeth during the fluoride content of drinking water is too high, fluoride tooth against the ameloblast cells, leading to dental fluorosis. Generally believed that the water fluoride level for a ppm (lmg / L) it is advisable that the concentration can effectively against dental caries. occurred without dental fluorosis. China's existing water quality standards for fluoride concentrations 0.5-1 ppm. Dental fluorosis age of excessive fluoride during tooth development only mineralization phase to enter the body can occur dental fluorosis. If in six, seven years of age, had been living in high-fluorine water, Even though he has also relocated to the inevitable after the eruption of permanent teeth involvement; Conversely, if the seven-year-old after moving into the high fluoride areas, it will not lead to dental fluorosis. Dental fluorosis popular around the world, Northwest China, North China, Northeast China and the southwestern region 19 provinces and cities have been found in dental fluorosis. Mild clinical performance : (Cretaceous-type) with a small number of teeth surface Cretaceous - or tan spot-block, no substantial defect. Moderate (pigmented) : The majority of the tooth surface with tan or brown patches, the surface is smooth teeth hard. Severe (defect type) : The majority of the whole tooth or teeth appeared dark brown patch, a bit, line sag and coloring. Treatment improved water source : the fluoride content of drinking water to areas with high fluoride treatment to make, which is fundamental to the preventive measures. Decoloration : 30% off liquid hydrogen fluoride plus five copies of ether into a bleach solution for bleaching. Photocurable repair : severe dental fluorosis available photocurable repair.
