摘要
目的 观察和了解改水降氟病情防治效果。方法 在病区设立 10 个重点监测点,对降氟效果、8~10 岁儿童氟斑牙、尿氟和水氟开展监测。结果 管理措施落实较好的改水工程占整个改水工程的 778% ,8~12 岁儿童氟斑牙率、尿氟和水氟含量呈下降趋势,或维持在正常水平,表明监测点的病情得到有效控制,且达到稳定控制状态。结论 对改水工程加强管理和维护,坚持长年饮用低氟水,饮水型氟中毒就能得到有效控制。
Objective To observe and know the preventive effect of lowering fluoride level in drinking water by altering water resources.Methods Ten surveying stations were built to observe the efficiency of the defluoridation construction,the dental fluorosis prevalence rate of 8~12 years old children and fluoride in urine and fluorid in water.Results 77.8% constructions were efficient,for the incidence of dental fluorosis,urinary fluorine and water fluorosis levels of school age children was reduced every year.It shows that these states of the dental fluorosis in surveyed village have been effectively and steadily controled.Conclusions Keep on drinking fluoride low water and preserving defluoridation are efficient measures for endemic fluorosis control.
