This project involves the same seven communities in Illinois that had been previously surveyed by the NIDR in April 1980. The communities were grouped according to the relation of their water fluoride concentration for the area (1, 2, 3, or 4-times optimal). Study participants consisted of children in two age groups, 8-to-10 and 13-to-15 years of age. The 8-to-10 year age group comprised children who received parental consent to participate and whose histories indicated that they had resided continuously since birth in their respective communities. The 13- to-15 year old group comprised only those children who were examined as 8-to-10 year olds in 1980. Examinations for the survey was conducted in April 1985. Dental caries was assessed with the DMFS index and fluorosis was measured with the Tooth Surface Index of Fluorosis, an index developed by NIDR for the 1980 survey. These indices were applied in both age groups by the same examiners who had used them in 1980. A new examiner assessed the prevalence of gingivitis and calculus in the entire dentition in the 13-to-15 year age group. A report presenting entire dentition in the 13-15 year age group. A report presenting findings on dental caries and fluorosis has been submitted for publication.

这个项目涉及伊利诺斯州的七个社区， 曾于1980年4月由NIDR进行过调查。 的 社区根据它们之间的关系进行分组， 该地区的水氟浓度（1、2、3或4倍 最佳）。 研究参与者包括两个年龄段的儿童 年龄在8至10岁和13至15岁之间。 8-10岁 一组由得到父母同意的儿童组成， 参与，其历史表明，他们曾居住在 自出生以来，一直在各自的社区工作。 13- 至15岁组仅包括那些 在1980年8到10奥尔兹的时候被检查过 性征聘考试 调查于1985年4月进行。 龋齿评估 用DMFS指数测定氟中毒程度，用牙槽骨测量氟中毒程度 氟中毒的表面指数，由NIDR开发的 1980年调查。 这些指数在两个年龄组中均得到应用， 1980年使用过的同一批检验人员。 新来的考官 评估牙龈炎和牙石的患病率在整个 13至15岁年龄组的牙列。 报告介绍 13-15岁年龄组的全齿列。 报告介绍 关于龋齿和氟中毒的调查结果已提交给 出版物
