This study is a follow-up of previous studies conducted by the NIDR in Illinois in 1980 and 1985 and in Iowa in 1982 to assess the prevalence of dental fluorosis and dental caries among schoolchildren exposed to different concentrations of fluoride in their drinking water. Both Illinois surveys were carried out in the same communities, which had naturally occurring fluorides in their water supplies at concentrations of approximately one, two, three and four times that recommended as optimal for those areas. In contrast, the Iowa communities had negligible concentrations of fluoride in their drinking water. The need to monitor for possible changes in the prevalence of dental fluorosis continues to receive high priority. Additional research also is needed to further elucidate and define current interrelationships between dental caries, dental fluorosis, and various concentrations of fluoride in drinking water. The continued availability of the same communities in Illinois and the identification of two communities in Nebraska with negligible concentrations of water-borne fluoride have afforded an excellent opportunity to address these research needs. Examinations were completed in April 1990 on approximately 300 schoolchildren ages seven through 16 in the two Nebraska communities. Each child was examined for dental caries using the DMFS index and for dental fluorosis using both Dean's Index and the Tooth Surface Index of Fluorosis. Examinations, using the same indices, were conducted in October 1990 in Illinois. Data from all study sites currently are being analyzed.

这项研究是 NIDR 之前进行的研究的后续研究 1980 年和 1985 年伊利诺伊州以及 1982 年爱荷华州评估患病率 接触氟斑牙和龋齿的学童中 饮用水中氟化物浓度不同。 两个都 伊利诺伊州的调查是在同一社区进行的，这些社区 供水中天然存在的氟化物浓度 大约是建议的一倍、二倍、三倍和四倍 最适合这些区域。 相比之下，爱荷华州社区 他们的饮用水中氟化物的浓度可以忽略不计。 需要监测牙科患病率可能发生的变化 氟中毒继续受到高度重视。 还进行了额外的研究 需要进一步阐明和定义当前的相互关系 龋齿、氟斑牙和不同浓度的 饮用水中的氟化物。 相同的持续可用性 伊利诺伊州的社区和两个社区的识别 内布拉斯加州的水性氟化物浓度可忽略不计 为满足这些研究需求提供了绝佳的机会。 考试于 1990 年 4 月完成，大约有 300 内布拉斯加州两个社区 7 至 16 岁的学童。 使用 DMFS 指数对每个儿童进行龋齿检查 使用 Dean 指数和牙齿表面指数来判断氟斑牙 氟中毒。 使用相同的指数进行的检查 1990 年 10 月在伊利诺伊州。 目前正在收集来自所有研究地点的数据 分析了。
