DENTAL CARIES AND FLUOROSIS IN AREAS WITH DIFFERENT WATER FLUORIDE CONCENTRATIONS

1980年4月，对1980年4月至1981年4月期间的 在伊利诺伊州的七个社区， 他们体内的天然氟化物浓度不同， 公共供水。 这些社区被分为四类 根据实际水氟近似关系 最佳氟化物浓度的建议 面积（1、2、3或4倍最佳）。 研究人群包括807名 年龄在8-16岁之间的学龄儿童，他们从出生起就一直生活在他们的家庭中。 各社区，并一直使用社区供应作为他们的 主要饮用水源。 用DMFS评估龋齿 指数和氟斑牙用Dean's指数和新的 牙齿表面氟中毒指数（TSIF） 评估氟中毒 每个孩子都有自己的指数。 此外，彩色照片 一些孩子的牙齿被用来描绘不同程度的 氟中毒 1982年4月，来自爱荷华州四个社区的316名儿童， 他们的饮用水中的氟化物浓度可以忽略不计 与伊利诺伊州的孩子们进行比较。 两份调查结果报告 伊利诺伊州的数据已经公布。 一位代表介绍了关于以下方面的基本调查结果： 龋齿和氟斑牙，用Dean's指数测量;其他 根据新的氟中毒牙齿表面指数提出了研究结果。 一 第三份报告，介绍了爱荷华州的数据，沿着补充发现 目前正在开发中。

In April 1980, a cross-sectional survey was made of the prevalence of dental fluorosis and dental caries in seven communities in Illinois that had different concentrations of naturally-occurring fluoride in their public water supplies. The communities were grouped into four categories according to the approximate relation of their actual water-fluoride concentration to the recommended optimal fluoride concentration for the area (1, 2, 3 or 4 times optimal). The study population consisted of 807 school children, ages 8-16, who had lived continuously from birth in their respective communities and had always used the community supply as their primary drinking water source. Dental caries was assessed with the DMFS index and dental fluorosis was measured with Dean's Index and with a newly developed tooth Surface Index of Fluorosis (TSIF). Fluorosis was assessed independently in each child by each Index. In addition, color photographs of the teeth of some children were taken to depict varying degrees of fluorosis. In April 1982, 316 children from four communities in Iowa with negligible concentrations of fluoride in their drinking water were examined for comparison with the children in Illinois. Two reorts of findings based on the Illinois data have been published. One presented basic findings on dental caries and dental fluorosis as measured with Dean's Index; the other presented findings based on the new tooth Surface Index of Fluorosis. A third report, presenting the Iowa data along with supplementary findings from Illinois, is currently being developed.
