Since the 1970s, most of the provinces, municipalities and autonomous regions of our country have carried out epidemiological investigations of endemic fluorosis (Fluorosis). On this basis, a large number of fluoride reduction wells and other Fluoride facilities. The national monitoring results from 1990 to 2005 showed that the completion rate of Ganshui Village increased linearly, and the detection rate of dental fluorosis among children with moderate to severe diseases dropped significantly. However, there are still many problems to be solved, such as the overall water rate is still not high, poor water management facilities, water diversion project
