摘　　要：目的调查不同饮水含氟量与氟斑牙发病关系,探讨实施改水降氟预防饮水型氟中毒的可行性。方法选择河北省承德市4个不同方位氟病村,调查8～12岁儿童氟斑牙患病率、饮水含氟量、尿含氟量。结果 4个不同方位的病村8～12儿童氟斑牙患病率及尿氟含量与饮水含氟量成正比。结论饮水含氟量低于1.0mg/L是防治饮水型氟中毒的关键。Objective To investigate the relationship between fluoride level in drinking water and pathogenesis of dental fluorosis,evaluate the feasibility of prevention water-related endemic fluorosis by reducing fluorite concentration in drinking-water.Method A large scale of study has been carried out in four villages of different directions in Chengde,investigate the dental fluorosis rate,fluoride level of drinking water and urine of 8 to 12 years old children.Results Among the children,the rate of dental fluorosis and fluoride level in urine are proportionate to fluoride level in drinking water.Conclusions The key to prevention of water-related endemic fluorosis is to maintain fluoride level below 1.0mg /L.
