【目的】了解西安市古汉城遗址区儿童地方性氟中毒现状,为饮水改造工程的实施提供科学依据。【方法】对古汉城遗址内11个村集中式饮用的井水用氟离子选择电极法对水氟含量进行测定,并用Dean氏法检查8~12岁儿童氟牙症患病情况。【结果】在汉城乡11个高氟村,检查8~12周岁儿童457人,检出氟牙症患者75人,检出率为16.4%,极轻患者57人(检出率为12.2%),轻度患者18人(检出率为3.9%),未见中度和重度氟牙症出现。【结论】古汉城遗址内8~12岁儿童氟牙症检出率16.4%。在保存古汉城遗址完整的同时,政府应加大力度进行饮水改造措施的实施,从根本上解决遗址内居民的饮水状况,从而有效地控制地方性氟中毒的流行。
【Objective】 To understand the current status of endemic fluorosis among children in the site of ancient Seoul in Xi’an, and to provide a scientific basis for the implementation of drinking water renovation project. 【Method】 Fluoride ion-selective electrode method was used to determine the fluoride content of drinking water in 11 villages in ancient Seoul site. Dean’s method was used to examine the prevalence of dental fluorosis in children aged 8 to 12 years old. 【Results】 457 children aged 8-12 years were examined in 11 high-fluoride villages in Seoul City. 75 people were diagnosed as dental fluorosis, the detection rate was 16.4%, and the number of extremely light patients was 57 (detection rate was 12.2%). , Mild patients 18 (detection rate was 3.9%), no moderate and severe dental fluorosis appeared. 【Conclusion】 The detection rate of dental fluorosis in children aged 8 ~ 12 years old in ancient Seoul was 16.4%. While preserving the integrity of ancient Seoul ruins, the government should step up its implementation of drinking water reform measures and fundamentally solve the drinking water conditions of residents in the sites so as to effectively control the prevalence of endemic fluorosis.
