目的 :了解吐鲁番干热饮水型氟中毒地区改水 16个月后居民的发病情况 ,以及低氟环境氟中毒地区短期防治效果。 方法:用流行病学方法对两病区儿童及部分成人进行调查 ,并采用氟离子选择电极、Dean氏法及拍片等方法分别对水、尿、牙齿及骨骼进行检查。 结果 :改水后两病区儿童氟斑牙患病率有一定的降低 ,尤其是低年龄儿童降低较明显 ,氟骨症病人骨关节症状有所减轻。改水前后两病区居民尿氟值和病人 X线征象没有明显变化 (P >0 .0 5 )。 结论 :改水后两病区儿童氟斑牙病情得到了一定控制和减轻 ,而氟骨症病人的症状和体征改变不明显。提示改水后近期防治效果不明显
Objective: To understand the incidence of residents in Turpan-Dry fluorosis-poisoning area after 16 months of water change and the short-term prevention and control of fluoride poisoning in low-fluorine environment. Methods: Epidemiological methods were used to investigate children and some adults in two wards. Fluoride ion-selective electrodes, Dean’s method and filming were used to examine water, urine, teeth and bone respectively. Results: The prevalence of dental fluorosis in children in the two wards after water diversion decreased to a certain extent. Especially in children with lower age, the incidence of dental fluorosis decreased slightly. There was no significant change in urinary fluoride and patient X-ray findings before and after water diversion (P> 0.05). Conclusion: The dental fluorosis has been controlled and relieved in both wards after water diversion, while the symptoms and signs of fluorosis patients are not obvious. Prompt water after the recent control effect is not obvious
