摘要
目的探讨高氟区氟牙症与龋病的流行特点。方法用氟离子选择电极法、Dean氟牙症分类标准和WHO口腔健康调查表龋齿记分方法对河北省吴桥县高氟区的水氟浓度、氟牙症指数和龋病患病情况进行调查。结果在水氟浓度 4 .5～ 5 .4mg/L的重病区患龋率 5 0 .95 % ,社区氟牙症指数 (communitydentalfluorosisindex ,FCI) 3.0 2 ;在水氟浓度 1.1～ 1.5mg/L的轻病区患龋率为 2 1.98% ,FCI为 0 .5 9。高氟区 10～ 14岁儿童第 1恒磨牙牙合面患龋率 78.5 1% ,第 2恒磨牙牙合面患龋 91.78%。Dean氟牙症记分为 0 ,0 .5 ,1,2 ,3,4的人群患龋率分别为 10 .5 3% ,2 9.0 3% ,2 8.0 4 % ,2 5 .71% ,4 7.0 4 % ,70 .0 0 %。结论高氟区重病区患龋率明显高于轻病区患龋率 ;高氟区 10～ 14岁儿童第 2恒磨牙牙合面患龋率高于第 1恒磨牙 ;高氟区 10～
ObjectiveTo study the prevalence of dental caries and fluorosis in the high fluoride areas.MethodsDental caries,concentration of fluoride in the water, dental fluorosis index and caries prevalence were studied in Wuqiao County of Hebei Province.ResultsThe prevalence of dental caries was 50.95 % and 21.98 % for children residing in areas with 4.5 - 5.4 mg/L and 1.1 - 1.5 mg/L fluoride in drinking water, and the community dental fluorosis index(FCI) was 3.02 , 0.59 , respectively. The occlusal caries prevalence of first molar in the high fluoride area was 78.51 % , while the second molar was 91.78 % . The caries prevalence of children with fluorosis index 0, 0.5 , 1, 2, 3, 4 was 10.53 % , 29.03 % , 28.04 % , 25.71 % , 47.04 % and 70.00 % . ConclusionThere is a positive correlation between the prevalence of dental caries and dental fluorosis index in the high fluororide areas. In the high fluoride area, the occlusal caries prevalence of the second molar is higher than that of the first molar. The fluorosis index in high fluoride areas increases with age from 10 to 14 years old.
