To determine the feasibility of water fluoridation to prevent caries in Kunming by investigating the epidemiological status of dental caries and dental fluorosis of children, and to provide the longitudinal reference data for the long-term epidemiology survey of dental caries and dental fluorosis in Kunming city. Methods Through stratified cluster sampling method, 212 5-year-old children and 1 149 12-year-old children were recruited in the survey. Dental caries condition of each child was clinically examined, dental fluorosis was examined in 12-year-old group. Results The prevalence of dental caries of primary teeth in 5-year-old group was 73.6%, mean value was 4.47± 4.39. The values of permanent teeth in 12-year-old group were 53.5% and 1.42±1.83. The prevalence of dental fluo- rosis in 12-year-old group was 4.1% and the average community fluorosis index was 0.03. Conclusion Based on the high prevalence of dental caries and the low prevalence of dental fluorosis, it is suggested that using water fluoridation to prevent caries is feasible and necessary in Kunming city.%目的 通过对昆明市儿童龋病和氟牙症的流行病学调查,为该区开展饮水加氟预防龋齿提供可行性依据,并为昆明市龋病和氟牙症长期流行病学研究提供基础数据.方法 采用分层、整群随机抽样方法,调查5、12岁2个年龄组儿童各212、1 149人,调查内容包括5、12岁儿童龋病患病现状以及12岁儿童氟牙症流行现状.结果 昆明市5岁儿童乳牙患龋率73.6%,龋均4.47+4.39; 12岁儿童恒牙患龋率53.5%,龋均1.42±1.83; 12岁儿童氟牙症患病率4.1%,社区氟牙症指数为0.03.结论 昆明市属于龋病患病状况较严重和氟牙症非流行区,从流行病学角度认为该地区具有调节水氟浓度预防龋齿的必要性及可行性.
