Resuits of the national surveillance on endemic fluorosis in Fengshun County of Guangdong Province in 2005-2006

Objective To investigated to implement condition of preventive measure and control effect for endemic fluorosis in Fengshun County from 2005 to 2006.Methods It was investigated according to the National Surveillance Program of Endemic Fluorosis.Hupo,Daizai and Anquan Villages of Tangxi Town in Fengshun County were selected as monitoring spots.The usage of reforming water facilities,fluoride content in drinking water and urine of children aged 8-12 years and the prevalence rate of dental fluorosis of children were investigated.Resul tsin 2005 and 2006.a total of 18 reforming water facilities were surveyed and six of which were damaged or out of service.In 2005,the fluoride content in drinking water in the 3 villages was 2.10,1.22 and 0.15 mg/L The prevalence rate of dental fluorosis of children aged 8-12 years was 54.23%(64/118),38.91%(79/203) and 9.10%(6/66).The urine fluoride content of children was 0.95,0.90 and 1.05 mg/L,respectively.In 2006,the fluoride content in drinking water in Hupo,Daizai and Anquan Village was 2.01,1.57 and 0.21 mg/L.The prevalence rate of dental fluorosis of children aged 8-12 years was 26.47%(27/102),12.50%(23/184)and 6.15%(4/65),respectively.The urine fluoride content of children was 0.97,0.61 and 0.59 mg/L.Conclusions The outcome of surveillance data in Fengshun County has reached the sanle level as that of non-disease area.However,the management of reforming water facilities should be improved.
