摘　　要：目的了解运城市地方性氟中毒病区改水后居民氟中毒病情现状。方法采用流行病学调查方法。结果重度病区侯家卓改水后饮水氟10年间稳定在1.0 mg/L以下,8～12岁儿童氟斑牙患病率及氟斑牙指数,随改水时间的延长而逐渐降低,改水12年后无新病例发生,儿童尿氟保持在1.0～1.4mg/L,成人氟骨症检出率明显降低。中度病区杜东庄改水后水氟为1.25 mg/L,超过改水标准,虽然以上几种指标呈下降趋势,但都高于侯家卓。结论饮水型地方型氟中毒病区改水后保证水源水氟稳定在1.0mg/L以下,是防治此病的关键。Objective To investigate the status of endemic fluorosis after practicing drinking-water improvement in Yuncheng City. Methods Retrospective epidemic methods. Results In the diseaseridden Houjiazhuo Village, the concentration of drinking-water fluoride was steadily under 1.0 mg/L during a period of 10 years drinking-water improvement. Both the dental fluorosis morbidity and dental fluorosis index in 8 -12 years old children showed a decrease trend along with the going of drinking-water improving,there was no new cffses occur after 12 years improvement. Fifteen years later, the urine fluoride of children maintained low level （1.0 - 1.4 mg/L）, and the bony syndromes of fluorosis in adults lightened gradually. Conclusion The key to prevent endemic fluorosis is to ensure the quality of drinking-water（the fluoride concentration is steadily under 1.0 mg/L）.
