目的:了解掌握呼和浩特市地方性氟中毒病情现状.方法:按照"2005年中央补助地方公共卫生专项资金地方性氟中毒调查项目实施方案",对我市所涉及的高氟病区村检查8～12周岁儿童氟斑牙患病情况,儿童氟斑牙检查采用Dean氏法.水氟检测采用氟离子选择电极法.结果:在4个县239个村庄检查8～12周岁儿童8 092人,检出氟斑牙患者2 779人,检出率为34.34%,其中可疑患者1 108人(检出率为13.69%),极轻患者1 113人(检出率为13.75%),轻度患者436人(检出率为5.39%),中度患者104人(检出率为1.29%),重度患者18人(检出率为0.22%).结论:儿童氟斑牙检出率大于30%,说明我地区氟中毒患病率较高,病情未被控制,防治措施没有到位,今后应采取对策改善现况,从而有效地控制地方性氟中毒的流行.%Objective: To investigated and master the status of endemic fluorosis in Huhhot. Methods: According to the national government investigation program with special subsidize of endemic fluorosis for public health in 2005, the dental teeth of children aged 8～12 years at school was examined with Dean's index in Huhhot. The fluoride content in drinking-water was determined by the fluoride selective ion electrode. Results: The dental fluorosis of 8092 children aged 8～12 years were examined in 239 villages of 4 counties, the total detectable was 2779. The detectable rate of dental fluorosis of children aged 8～12 years was 34.34 %. Including suspicious patients 1108 (the prevalence rate is 13.69 %), tiny patients 1113 (the prevalence rate is 13.75%), light patients 436 (the prevalence rate is 5.39 % ), moderate patients 104 (the prevalence rate is 1.29 %), severe patients 18 (the prevalence rate is 0.22 % ). Conclusions: The total detectable rate of children dental fluorosis was above 30 %, and the prevalent rate of fluorosis was high and endemic fluorsis was not be controlled. From now on, we must take the way to deal with a situation to improving the present situation of manage and usage for the well of control fluorosis in order that advance the work of control fluorosis.
