DENTAL DISORDERS IN AREAS WITH DIFFERENT WATER-FLUORIDE LEVELS

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 根据社区之间的关系对社区进行了分组 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 8至10岁和13至15岁的群体。8到10岁的孩子 小组由获得父母同意的儿童组成 参与，其历史表明他们曾居住过 从出生起就在各自的社区持续存在。13个- 至15岁的群体只包括那些 1980年，作为8至10岁的儿童接受了检查。参加考试的 调查是在1985年4月进行的。对龋齿进行评估 用DMFS指数和牙齿测量氟中毒 由NIDR开发的氟中毒表面指数 1980年的调查。这些指数在这两个年龄组都是通过 1980年使用过它们的同一批考官。一位新的考官 评估整个牙周炎和牙石的患病率 13至15岁年龄组的牙列。提交的报告 13-15岁年龄组的整个牙列。提交的报告 关于龋齿和氟斑牙的研究结果已提交给 出版。

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.
