Caries incidence for 2 years after discontinuation of school-based fluoride mouthrinsing (5 times/week, 500ppm F), which was practiced at an elementary school for 6 years, was evaluated by tooth types of permanent dentition and duration of fluoride exposure.<BR>Incremental DMFT rates of the fluoride group (N=100) were lower than those of the control group (N=105) for all tooth types. Statistically significant differences between the two groups were observed in lower first and second molars (p<0.01, p<0.001) and all upper teeth except canines (p<0.05, p<0.01, p<0.001). In the fluoride group, caries increments were different for each tooth type and incremental DMFT rates of molars (11-49%) were much higher than those of the other tooth types (0-5%) in both upper and lower dentition. For all tooth types, however, no significant relationship between caries increments and previous duration of fluoride exposure in the elementary school was observed.<BR>The results of our study suggest that the cariostatic effects of fluoride mouthrinsing are not likely to be accumulated with the passage of time and it is necessary to continue the program until the eruption of second molars is completed.
