To dynamically observe the effect of endemic fluorosis prevention by lowering fluoride in drinking water, and to scientifically direct the endemic fluorosis control, according to The National Standard Method of Surveillance on the Endemic Fluorosis in China, three villages of Lushan County, where water resources had been improved, including Shangtang, Xiatang and Chuolou were surveyed once a year for 10 consecutive years. In this survey, the rate of children's dental fluorosis tended to decrease year by year, and significant difference was observed compared with previous data. But it wasn't below 30%, the national epidemic standard.
