A comparison of a waterpik dual-motor powered toothbrush and a manual toothbrush in affecting interproximal bleeding reduction and dental biofilm accumulation.

Objective: This single-blind, 21-day clinical study was designed to compare the effectiveness of a dual-motor powered toothbrush (SynchroSonic) and a manual toothbrush in affecting interproximal bleeding reduction and dental biofilm accumulation in a cohort of 70 subjects.

Methodology: After baseline evaluations of soft tissue trauma, dental biofilm and interproximal bleeding, subjects were randomly assigned to one of the two experimental groups, given toothbrushing instructions and had their teeth cleaned. At 21 days, the clinical parameters were again evaluated.
