A 4-week randomized controlled trial evaluating plaque and gingivitis effects of an electric toothbrush in a paediatric population.

Background: Few extended studies have explored oscillating-rotating (O-R) toothbrush efficacy in young children.

Aim: To compare the efficacy between O-R and manual toothbrushes in reducing plaque and gingivitis after 4 weeks in children.

Design: This was a randomized, parallel-group, examiner-blind, clinical trial.
