Abstract:
Objective In order to explore the effectiveness of defluoride project on the control of endemic fluorosis in Yantai economic & technological development area. Methods Nine hundred forty-five children aged 7-12 were selected in 4 endemic fluorosis disease areas (Guxian,Bajiao,Dajijia Streets and Changjiang community) and the control area of Yantai economic & technological development area. Prevalence of children's dental fluorosis was determined by Dean method. Water fluoride content was measured in the 4 endemic fluomsis disease area by means of fluorides ion selective electrode. Results Childr dental fluorosis prevalence rate in Guxian,Bajiao,Dajijia Streets and Changjiang community was respectively 30.1% (55/183),41.2% (73/177),33.7% (66/196),31.8% (64/201),higher than those in the control area [13.3% (25/188)]; the median of water fluoride in the 4 disease areas was 1.84,3.46,2.39,2.10 mg/L,respectively,higher than the National Health on the control of endemic fluorosis is not obvious,Standard (1.00 mg/L). Conclusions Effect of the defluoride project in Yantai economic & technological development area needs to be improved.
