Plaque Removal

Many studies that compare an automated toothbrush to a manual brush evaluate plaque removal.3-16 In most instances, the automated product removed more plaque than the manual. An exception is a 12-month study by Ainamo et al. that found no statistical differences between an oscillating brush and a manual control.7 In comparison, other studies showing greater plaque removal were of shorter duration ranging from four weeks to eight months.3-6,8-14,16
