School-based supervised toothbrushing (STB) vs no intervention

Caries increment on tooth surfaces (dmfs/DMFS) (prevented fraction) · Children in school or kindergarten settings (aged 3-14 years)

School-based supervised toothbrushing produces a small but statistically significant reduction in tooth-surface caries (DMFS/dmfs SMD -0.22, 95% CI -0.42 to -0.01; ungraded).

School-based supervised toothbrushing (STB) vs no intervention

Dental caries increment, DMFT/dmft (whole-tooth level) · Children in school or kindergarten settings (aged 3-14 years)

School-based supervised toothbrushing has no statistically significant effect on whole-tooth caries (DMFT/dmft SMD 0.05, 95% CI -0.27 to 0.37; ungraded).
