Title Rotation-Oscillation Toothbrush More Effective In Plaque Removal Than Sonic-Powered Toothbrush
Clinical Question In an adult, is use of a sonic toothbrush more effective than use of an oscillating/rotating powered toothbrush in plaque removal?
Clinical Bottom Line Both single-use RCTs study as well as the continuous 12-week RCT study suggests with statistically significance, that a rotation-oscillation toothbrush yielded greater reduction of plaque than sonic-powered toothbrush.

Key resultsSingle-brushing use of the rotation-oscillation toothbrush decreased overall plaque scores by 12.1% compared to the sonic-powered toothbrush, with a 7.9% reduction for buccal surfaces, and an 18.7% reduction for lingual surfaces.

Key resultsSingle-brushing use of the rotation-oscillation resulted in a 21.1% overall plaque reduction, with a 23.7% decrease at the gingival margin locations, and a 22.3% decrease at interproximal areas, relative to the sonic-powered toothbrush.

Key resultsIn a continuous 12-week study, both toothbrushes resulted in significant reduction of gingivitis scores, gingival bleeding sites, and plaque scores when compared to the baseline. However, the rotation-oscillation toothbrush demonstrated statistically significant lower gingivitis scores (8.2% difference), reduced gingival bleeding sites (29.4% greater reduction), and lower plaque scores (33.3% lower) compared to the sonic toothbrush.

Comments on
The Evidence
Results of two single studies and the 12-week study are consistent with existing research regarding the superiority of rotation-oscillation toothbrushes compared to sonic toothbrushes. The study design was appropriate allowing for the ability to tightly control study conditions, and treatment groups were well balanced. All studies were supported by the Procter & Gamble Company (manufacturer of the Oral-B Triumph toothbrush).
Applicability All three studies demonstrated superior plaque removal utilizing the rotation-oscillation toothbrush compared to the sonic toothbrush. However, this does not automatically translate into clinically relevant outcomes measures such as gingival/periodontal health over an extended period of time, which require long-term randomized controlled clinical trials.
