Analysis on Fujian Endemic Fluorosis surveillances of Central Transfer Payment Project in 2010

Objective:To assess the current status of endemic fluorosis areas in Fujian. Methods Using stratified cluster sampling,2 counties were sampled from all 36 endemic fluorosis counties,Drinking water fluoride content was detected in each site,prevalence of dental fluorosis was observed in children aged 8 to 12 years,and skeletal fluorosis census was taken for adults aged 16 or over,moreover,X-ray test was serviced for suspect patient. Results the rate of Drinking water fluoride is 94.1%; children dental fluorosis cases were found and positive rate was 0%; dental fluorosis in Changtai county which scrapped water fluoridation project was higher to close to prevalence but all the other were negative; detection rate of skeletal fluorosis was 0.06% via X-ray. Conclusion Water-improving project is very effective in water-drinking endemic fluorosis areas.
