: Many studies during the last 30 years have demonstrated the effectiveness of fluoride applications to inhibit caries in Japan and other countries The present study was examined the effects of a school-based fluoride mouth rinsing program as a caries prevention method The subjects in this study were 102 children at one elementary school in east Hokkaido which has had a fluoride mouth-rinsing program using 0 2% neutral NaF solution weekly for three years The control group was 163 children at another elementary school, which had a non- fluonde mouth rinsing program in the same town The DMFTindex in all grades of both schools were calculated from the data of the school dental examination Mann-Whitney U-test and Wilcoxon signed rank test were used for the statistical analysis The results were as follows 1) The caries inhibition rate of 4th and 5th grade children in the fluoride mouth-rinsing program school for three years were significantly higher than that of the same grades in the control school And caries inhibition rate of 4th grade children who had continued the fluonde mouth-rinsing program from 1st grade was 63 4% (p<0 05) 2 ) The caries inhibition rate of 6th grade children in the fluonde mouth-rinsing program school was 19 0% compared with 15% of the same grade in the control school, but this difference was not significant The results suggested that the school-based fluoride mouth-rinsing program could achieve high canes-preventive effects, especially when started from early grades It is concluded that to protect permanent teeth including first molars from caries, an active and continuous fluoride application program from before eruption of permanent teeth, is necessary from entering elementary school This is supported by the data of the high inhibition rate of 4th grade children who had continued the fluoride mouth-rinsing program from 1st grade
