Abstract

The cariostatic effect of fluoride mouthrinsing with dilute fluoride solution in the school dental health programs was examined. The subjects were 138 children (75 of boys and 63 of girls) who carried out fluoride mouthrinsing with solution of 100 ppmF- for 6 years and 105 children (65 of boys and 40 of girls) who had no fluoride mouthrinsing were analysed by cohort study from 1983 to 1989. The cariostatic effect was evaluated by DMFT index and DMF rate for each tooth type in each erupted school grade. The increment of DMFT index was less than that of the control group. There was a clear cariostatic effect with the advance in the school grade. DMF rate for each tooth type of 1 in 2nd grade and 2 in 3rd grade students showed a statistically significant difference. Both that of upper and lower first molars in 1st and 2nd grade also showed the same result as that of upper incisors. In conclusion, a high cariostatic effect was obtained by introducing the use of fluoride mouthrinsing with a solution of 100ppmF- to the school dental health program, and the observation of DMF rate for each tooth type classified with each erupted school grade was a useful method to evaluate the cariostatic effect of fluoride mouthrinsing.

摘要

在学校口腔健康项目中，对使用稀释氟溶液进行含氟漱口水漱口的防龋效果进行了研究。研究对象为138名儿童（75名男孩和63名女孩），他们使用100ppmF⁻溶液进行含氟漱口水漱口，为期6年；以及105名未进行含氟漱口水漱口的儿童（65名男孩和40名女孩），从1983年至1989年采用队列研究进行分析。通过乳牙龋失补牙面数（DMFT）指数和各萌出年级每种牙型的龋失补发生率（DMF率）来评估防龋效果。DMFT指数的增幅低于对照组。随着年级的升高，有明显的防龋效果。二年级学生每种牙型的DMF率为1以及三年级学生为2，显示出统计学上的显著差异。一年级和二年级上下颌第一磨牙的DMF率与上颌切牙的结果相同。总之，将使用100ppmF⁻溶液的含氟漱口水引入学校口腔健康项目可获得较高的防龋效果，观察按各萌出年级分类的每种牙型的DMF率是评估含氟漱口水防龋效果的一种有用方法。
