OBJECTIVE: To examine the effect of reported toothbrushing frequency and method of rinsing after brushing on caries experience and increment. METHODS: Data are presented from 2621 adolescents (mean age 12.5 years at outset) participating in a 3-year double-blind caries clinical trial. At baseline, examiners questioned each participant about their toothbrushing habits, and at subsequent examinations, this information was obtained using a self-administered computer-based questionnaire. Participants used a fluoride-containing dentifrice throughout and clinical examinations were conducted using a mirror, CPITN probe and fibre-optic transillumination. RESULTS: The reported brushing frequency increased throughout the trial. Caries experience at baseline was inversely related to toothbrushing frequency with mean DMFS=9.66, 8.12 and 7.63 respectively for <1/day, 1/day and >1/day brushers (P<0.001). Mean 3-year DMFS increments of 8.90, 6.63 and 5.48 (P<0.01) were observed in those reporting to brush <1/day, 1/day or >1/day, on not less than two of the three clinical examinations during the trial. Caries increment was also significantly related to the claimed method used to rinse post-brushing. Overall frequency of brushing and rinsing method accounted for over 50% of the explained variance in the ANOVA model used to analyse the DMFS increments. CONCLUSIONS: Stated toothbrushing frequency and rinsing method after brushing were found to be strongly correlated with caries experience and ...
