本研究的目的是观察氟滴预防儿童乳牙龋的作用。由幼儿园老师使用，剂量根据美国儿童牙科学会推荐标准，并参照成都市饮水氟含量制定，３岁以前每日给０．２５ｍｇ（２滴／日），３岁以后每日给０．５ｍｇ（４滴／日），观察３年，结果表明：参加本项目的儿童较对照组儿童龋病患病明显减少，随着项目实施时间的延续，效果持续增加。用氟组与对照组的ｄｍｆｔ为２．２１与４．３２。新龋增加分别为１．７６与３．９２。１、２、３年后用氟滴组与对照组相比ｄｍｆｔ分别下降３５．８４％、４１．７７％、４８．８４％。与国外文献报导的效果接近。表明氟滴项目是适合在幼儿园开展预防龋病的有效措施。
The purpose of this study was to observe the effect of fluorine droplets in preventing deciduous caries in children. By the kindergarten teacher, the dosage according to the American Children's Dental Society recommended standards, and with reference to drinking water fluoride content in Chengdu, before the age of 3 to 0.25mg (2 drops / day), 3 years after the daily 0.5mg (4 Drops / day), observed for 3 years, the results showed that: Children participating in the project than the control group significantly reduced caries prevalence of children, with the project implementation time continues, the effect continued to increase. The dmft between the fluoride group and the control group was 2.21 and 4.32. The increase of new caries was 1.76 and 3.92, respectively. Compared with the control group, the dmft decreased by 35.84%, 41.77% and 48.84% respectively in the fluoride group and the control group. Close to the results reported in foreign literature. It shows that the fluorine droplet project is an effective measure to prevent dental caries in kindergarten.
