The effectiveness of manual versus powered toothbrushes for plaque removal and gingival health: A meta-analysis

Abstract

In general there was no evidence of a statistically significant difference between powered and manual brushes. However, ionic brushes significantly reduce plaque and gingivitis in both the short-term evaluations. The clinical significance of this reduction is not known. Observation of methodological guidelines and greater standardization of design would benefit both future trials and meta-analyses.
