摘　　要：目的调查埇桥区饮水型氟中毒病区水氟及儿童氟斑牙患病率,为改水降氟措施提供依据。方法对埇桥区16个监测乡镇105个病区村开展水氟监测;调查各病区村8~12岁儿童氟斑牙患病情况。结果 16个监测乡镇水氟均值范围在0.59~1.41 mg/L。共检查8~12岁儿童13 936人,检出氟斑牙患者2 162人,氟斑牙患病率15.51%,氟斑牙指数为0.39,其中极轻度1 695例,轻度446例,中度20例,重度1例,8岁儿童氟斑牙患病率最低,9岁儿童氟斑牙患病率最高,不同年龄儿童氟斑牙患病率差异有统计学意义(χ~2=19.09,P<0.01)。结论埇桥区105个氟病区村,部分乡镇行政村儿童氟斑牙患病率较高,与十二五规划控制目标有较大差距,需要进一步加大改水力度,有效地控制水氟含量和氟斑牙病情。Objective To investigate fluorine content in water and prevalence of dental fluorosis of children in drinking - water type fluorosis areas in Yongqiao district, and provide the basis for formulation of water defluoridation measures in 13th Five - Year planning. Methods Determinating results of fluorine content in water and situation of dental fluorosis in children aged 8 - 12 from 105 endemic fluorosis villages in 16 monitoring townships based on the application of the census. Results The water fluoride average ranged in 0.59 - 1.41mg/L in 16 monitoring townships. 2162 patients with dental flu- orosis were found in 13936 children aged 8 - 12 include 1695 very mild cases （ 12. 16% ）, 446 mild cases （ 3.2% ）, 20 moderate cases（ 0.14% ） , 1 severe eases（ 0. 007% ） and no defect of dental fluorosis cases, and the dental fluorosis index was 0.39. The detection rate of dental fluorosis of 8,9,10,11 and 12 years old group were 13.74%, 17.21%, 16.72% , 14.64% and 15.60%. There were significant differences in the detection rates of all age groups （χ2 = 19.09 ,P 〈 0.01 ）. Conclusion There are 105 endemic fluorosis villages in part of which were with highei prevalence of dental fluorosis of children. There is a big gap to the planning control targets in 12th Five - Year, so the quality of local drinking water should be further improved to effectively control water fluoride and dental fluorosis.
