This project involved 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 were 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 findings on dental caries and fluorosis has been published.

该项目涉及伊利诺伊州相同的七个社区 曾在1980年4月接受过NIDR的调查。这个 根据水的关系对社区进行了分组 该地区的氟化物浓度(1、2、3或4倍为最佳)。 研究参与者由两个年龄段的儿童组成，年龄从8岁到 10岁和13至15岁。8至10岁年龄组包括 获得父母同意参加的儿童，其 历史表明，他们从出生起就一直居住在这里。 在他们各自的社区里。13至15岁的人群 只包括那些在8岁到10岁之间接受检查的儿童 1980年的奥兹。这项调查的检查是在4月份进行的 1985年。用DMFS指数和氟斑牙评估龋病 用氟斑牙牙面指数进行测量 由NIDR为1980年的调查而开发。这些指标被应用于 这两个年龄段的考官都是由1980年使用过它们的同一名考官进行的。 一名新的检查员评估了牙周炎和牙结石的患病率 在13至15岁的整个牙列中。一份报告 介绍了关于龋齿和氟骨症的研究结果 出版了。
