Powertoothbrushing for Treating Gingivitis

In this single-masked, parallel-armed, interventional clinical trial for treatment of gingivitis the investigators will assess the use of an oscillating-rotating powered toothbrush in comparison to the use of a manual toothbrush over 12-weeks in the absence of interproximal hygiene. The primary outcome variable is the change from baseline in the Modified Gingival Index at 2, 4 and 12-weeks from Baseline. Secondary outcome variables include change from baseline in bleeding on probing as well as change from baseline in the Turesky Modification of the Quigley-Hein Plaque index measuring overnight plaque formation. There will also be an assessment of single use efficacy in reduction of overnight plaque levels at the baseline visit t
