Objective To investigate the implementation of drinking water fluorosis and water and fluoride prevention measures. Methods According to the requirements of the national drinking water fluorosis monitoring program, light, medium and heavy ward monitoring points were selected for investigation. The survey included water fluoride, urinary fluoride, dental fluorosis in children. Results The factory outlet water and water fluoride value of the three ward types villages were both <1.2 mg / L. The prevalence rates of dental fluorosis in light, medium and severe wards were 23.08%, 15.05% and 7.35% respectively. Conclusion It is necessary to strengthen health education after fluoride is changed by water, instruct the masses to persist in drinking low-fluorine water, and to obtain effective control of endemic fluorosis in drinking water.
