慢性地方性氟中毒病区氟牙症指数标准的探讨

The Evaluation of Dental Fluorosis Indices in an Area of Epidemic Fluorosis

为探索各种氟牙症指数在氟中毒病区划分与防治效果评价方面的意义,作者对四川彭水县小厂乡及其邻近三个乡镇的在校中小学生2780人,采用三度法、Dean's 法、TF 法进行了对比检查。结果表明:TF 法优于其它标准,对病区的划分及防治效果的评价更为准确适用,可作为慢性地方性氟中毒病区划分及防治效果观察的指标之一。年龄组的选择,以12～13岁年龄组作为评估对象较为适宜。

Xiao Chang district of peng Shui county in Sichuan province is one of the most se-rious cases of epidemic fluorosis in China.Here,both of the food and atmosphere arepolluted by coal smoke which contains fluoride.To study the prevention and treatment of fluorosis,The first need is to study thesignificance of the criteria of dental fluorosis indices.Therefore,in October 1988,theauthors investigated 2780 school children in Xiao Chang and three neighboring districtsThe results showed that dental fluorosis was prevalent in 97.68% of the children surve-yed Furthermore,96.86% of the children have serious dental fluorosis and 100% of the12-13 years age group tested positive for dental fluorosis.The authors concluded that 1).the 12-13 years age group would serve as the bestevaluating subject,and 2.the TF method is the most effective and applicable.
