Objectives: To assess the efficacy of a child’s power toothbrush to remove plaque in a single brushing session, in comparison with a children’s manual toothbrush.

Methods: A systematic review includes randomized clinical trials (RCTs) of studies comparing both manual and electrical toothbrushes among children. The protocol included guidelines for the literature search, study quality considerations, patients’ inclusion criteria, outcome parameters, and statistical methods to be used in the meta-analysis.

Results: From a total of 1,502 articles, following the selection process, only 9 RCT in vivo studies of two study groups, electric and manual toothbrushes, were suitable for meta-analysis. Heterogeneity test Cochrane Q of the efficacy of Electric toothbrush vs. manual toothbrush on preventing dental plaque among children (212.449; df = 8; p < 0.0001) demonstrated statistically significant results. In performing 2 tests of “bias indicators” both groups didn't yield statistically significant results (p=0.602 and p=0.414 respectively), indicative a low possible of bias. The results indicates that the preventive effect of the electric toothbrush pooled means of the fixed effect (FE) model and the random effect (RE) model (0.324 and 0.261 respectively) were highly statistically significant (p<0.001).

Conclusions: With regard to the forest plots and the pooled mean effect size the results indicated that the Electric TB might be more effective than Manual TB, guided by 7 studies with statistically significant effect, and with an overall statistical significance.
