DENTAL DISORDERS IN AREAS WITH DIFFERENT WATER-FLUORIDE LEVELS

这一项目是荷兰发展研究所在2002年进行的一次调查的后续行动。 1980年4月，伊利诺斯州的四个地区天然存在氟化物， 在他们的饮用水供应中， 大约是建议最佳值的1、2、3和4倍 对于这些地区。 同样的社区被重新访问， 在两个相同的年龄组（8-10岁和13-15岁）中， 1980. 8至10岁年龄组的研究参与者包括所有 获得父母同意参加的年龄段的儿童， 他们的居住历史，他们自出生以来一直居住在 各自的社区。 13至15岁的年龄组只包括 这些孩子在1980年8到10奥尔兹时接受了检查。 1985年4月进行了检查，以评估 龋齿和氟斑牙。 此外该 对所有儿童的牙龈炎和牙结石患病率进行了评估 在13到15岁的年龄组。

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.
