摘要
[目的]了解中度氟病区饮用低氟自来水预防儿童氟斑牙的效果并探讨其影响因素。[方法]对选中的4个村所有8．12岁儿童用Dean＇s法进行氟斑牙诊断并对其所在家庭进行问卷调查。[结果]改水3年的村中饮用自来水的儿童并没有表现出预防氟斑牙的效果。改水8年以上的两村饮用自来水的儿童氟斑牙患病率明显降低，严重程度明显减轻且均已达到控制标准。但两组预防氟斑牙的效果无明显差别。儿童所在家庭的经济条件、开始饮用自来水的年龄和持续饮用时间被纳入到logistic回归方程。[结论]在中度氟病区，改水8年以上的病区村，饮用自来水预防儿童氟斑牙效果明显。可达到控制标准。儿童所在家庭的经济条件、开始饮用低氟自来水的年龄和持续饮用时间是影响预防氟斑牙效果的重要因素。
[Objective] To find out the effect of drinking tap water with low fluoride to prevent children＇s dental fluomsis and its influential factors in moderate fluorosis prevalent regions. [ Methods] The children from 4 villages selected were diagnosed for dental fluorosis with Dean＇s method and their families were investigated with questionnaire. [Results] In the village water-improved for 3 years, no effect of dental fluorosis prevention was found in the children who had drunk tap water. In the two villages water-improvod for no less than 8 years, the prevalence and severity of dental fluorosis in the children scholars who had drunk tap water significantly decreased and met the control standard. There was no significant difference in the effect of dental fluoresis prevention between the two groups of children. The economic conditions of children＇s families, the beginning and the length of the period in which children drank tap water were entered in the logistic regression equation, [ Conclusions ] In moderate flurosis prevalent regions and in the villages water-improved for no less than 8 years, the effect of dental fluorosis prevention is significant and the prevalence can meet the control standard in the children who had drunk tap water. The economic conditions of children＇s families, the beginning and the length of the period in which children drank tap water with low fluoride are important influential factors on the effect of dental fluorosis prevention,
