The purpose of the present study was to determine whether the caries-preventive effect of school-based programs with fluoride (F) mouthrinsing or toothbrushing was evident at the end of a post-treatment follow-up period of 11 years. Two groups of subjects examined at 14 years of age (born in 1960), who had participated in fortnightly F rinsing (n = 52) or in F brushing 4-5 times a year at school (n = 50), were re-examined radiographically and completed a questionnaire at age 25 years. A comparison group of 25-year-olds (n = 51) was also included. Analyses of variance showed that the benefits of participation in school-based F programs seem to have been lost. It appears that these caries-preventive programs have delayed rather than prevented caries and that F toothpaste and other caries-preventive efforts have been insufficient to avert a substantial caries activity during the follow-up period.
本研究的目的是确定在为期11年的治疗后随访期结束时，以学校为基础的含氟（F）漱口水或刷牙项目的防龋效果是否明显。两组14岁（出生于1960年）的受试者，一组每两周参加一次F漱口水项目（n = 52），另一组每年在学校进行4 - 5次F刷牙（n = 50），在25岁时再次进行影像学检查并填写问卷。还纳入了一组25岁的对照组（n = 51）。方差分析表明，参与以学校为基础的F项目的益处似乎已经消失。这些防龋项目似乎只是延缓了而非预防了龋齿，并且含氟牙膏和其他防龋措施在随访期间不足以避免大量的龋齿活动。
