This project is a followup to a previous survey carried out by the NIDR in April 1980 in four areas of Illinois that have fluorides naturally occurring in their drinking water supplies at concentrations of approximately one, two, three and four times that recommended as optimal for those areas. The same communities were revisited to examine children in two of the same age groups (8-10 and 13-15 years) that were evaluated in 1980. Study participants in the 8-to-10 year age group comprised all children of those ages who received parental consent to participate and whose residence histories 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 were conducted in April 1985 to assess the prevalence of dental caries and dental fluorosis in both age groups. In addition, the prevalence of gingivitis and dental calculus was assessed in all children in the 13-to-15 year age group.

这个项目是NIDR在#年进行的一项调查的后续行动 1980年4月在伊利诺伊州四个天然含有氟化物的地区 在他们的饮用水中发生的浓度为 大约是建议的一倍、两倍、三倍和四倍 对于那些地区。同样的社区也被重新访问以检查儿童 在两个相同的年龄组(8-10岁和13-15岁)中， 1980年。8至10岁年龄组的研究参与者包括 获得父母同意参加的这些年龄段的儿童和 他们自出生以来一直居住在谁的居住史 他们各自的社区。13至15岁的年龄组仅包括 这些儿童在1980年接受了8至10岁的检查。 1985年4月进行了检查，以评估患病率 两个年龄组的龋病和氟斑牙。此外， 对所有儿童的牙周炎和牙结石的患病率进行了评估 在13至15岁年龄组。
