摘　　要：目的了解饮水型地方性氟中毒病情的现状、消长和发展趋势。方法在水牛陈监测点调查8岁～12岁儿童氟斑牙患病情况、尿液含氟量并检测居民饮用水含氟量。结果水牛陈监测点在2009年改水后水源含氟量控制在1．0mete以下，2007—2011年8岁-12岁儿童氟斑牙检出率分别为70．37％、55．17％、65．22％、53．12％、45．83％，改水后3a与改水前氟斑牙检出率有下降趋势，但差异无统计学意义，改水后第一年儿童尿氟有显著下降。结论降氟改水能有效控制氟中毒病情的发展，短期内尿含氟量下降明显。Objective To understand the current situation, and development trends of drinking water type endemic fluorosis. Methods To determined fluoride levels of drinking water ,and dental fluorosis and fluoride content in urine of the children aged 8 to 12 of the moni- toring village. Results After water improving in 2009 the water fluoride content of the monitoring village was controlled at below 1.0 mg / L. The detection rate of dental fluorosis of children aged 8 to12 in 2007-2011 were 70.37 %, 55.17 %, 65.22 %, 53.12 %, 45.83 %. Three years after water improving and the detection the rate of dental fluorosis of children in downward trend, but not significantly change, the first year after water improving the children＇s urine fluoride significantly decreased. Conclusions The program of water defluorination can effectively control the development of fluorosis, and in a short amount the fluoride content in urine of the children decreased significantly.
