摘　　要：为探讨不同饮水氟浓度、不同营养水平对人群龋齿的影响，分低水氟（＜０．３ｍｇ／Ｌ），适宜水氟（１ｍｇ／Ｌ）和高水氟（＞４．８ｍｇ／Ｌ）三个氟水平，每一氟水平又分正常低营养二组，共６个人群组，每组１２０人，平均年龄４６岁，调查计算了人群日总摄氟量，检查了冠面龋与根面龋。同时每组调查了８～１５岁学生１００人。结果经统计分析表明，低饮水氟地区人群的龋患率与龋患指数均明显高于其他两组。低水氟与适宜水氟组人群均无氟斑牙发生，高饮水氟组发生了严重的氟中毒。此结果证明，适宜水氟（１ｍｇ／Ｌ）能起到预防氟中毒与预防龋齿的双重作用。不同营养水平方面，只在低饮水氟２组之间表现出来，低营养组的龋患率明显高于正常营养组。To investigate the effect of different levels of fluoride contents in drinking water and the nutritional condition on the prevalence of caries.Low(<03mg/L),adequate (1mg/L) and high (>4.8mg/L) fluoride contents in drinking water groups,adequate and inadequate nutrition groups for each fluoride level respectively were studied.Daily total intake fluoride,coronal caries and root caties were examined from mean 46 age 120 adults and 8￣15 age 100 students in each group in 6 groups in total.The statistical results showed that the prevalence of coronal and root caries were decreasing as increasing of fluoride content in drinking water,and nutrition had effected coronal caries in low fluoride group only.However,severe dental fluorosis was observedonly in group with high fluoride in drinking water,but not in other two groups.The data obtained from the present study demonstrated that the adequate concentration of fluoride (1 mg/L) in drinking water was benefit for preventing dental fluorosis.
