School-based dental health activities conducted in Hiraizumi over the past 20 years have remarkably improved the dental health status of schoolchildren. For example, DMFT index of 12-year-old children decreased to 1.5 in 1998, one-half that of the national average. School dental health activities, which were focused on dental health education, resulted in an increase of filled teeth rates, a decrease in the number of missing teeth, and a decline in incisor caries (1979-1986). In addition, the introduction of a school-based fluoride mouth-rinsing program (1986 - ) showed a positive effect on the prevention of dental caries; a significant decrease was observed in the overall prevalence of dental caries, particularly in the molars. In Japan it seems advantageous to promote the dental health of schoolchildren by school-based programs that combine dental health examination, dental health education and fluoride mouth-rinsing program. Especially, to prevent dental caries in the mandibular first molars more effectively, it is recommended to start fluoride mouth-rinsing at age 5.
过去20年在平泉开展的校内牙齿健康活动显著改善了学童的牙齿健康状况。例如，1998年12岁儿童的龋失补指数降至1.5，为全国平均水平的一半。专注于牙齿健康教育的校内牙齿健康活动使补牙率上升、缺牙数量减少，且门牙龋齿率下降（1979 - 1986年）。此外，引入校内含氟漱口水项目（1986年起）对预防龋齿显示出积极效果；龋齿总体患病率显著下降，尤其是在磨牙方面。在日本，通过结合牙齿健康检查、牙齿健康教育和含氟漱口水项目的校内项目来促进学童牙齿健康似乎是有益的。特别是，为了更有效地预防下颌第一磨牙龋齿，建议在5岁开始使用含氟漱口水。
