Comparison between oscillating-twisting rotating of brush head vs a characteristic sweeping bristles motion on reducing oral inflammation

Background: The aim of present study was to clinically assess and compare a sonic toothbrush versus a rotating oscillating power toothbrush on plaque removal and gingival health in reducing plaque and bleeding on probing. Methods: Patients were selected according to specific inclusion and exclusion criteria and they were enrolled in test group or control group using Random Allocation Software. Visual score plaque index (PI) was recorded by the same blind operator using a plaque revelator and bleeding on probing (BoP) index was recorded using a periodontal probe at baseline, 15th day and 30th day. Results: The group of patients who used sonic toothbrush showed a greater reduction of PI and BoP comparing with patients who used rotating-oscillating power toothbrush. Conclusions: Although this pilot study has several limitations, it seems to indicate that sonic toothbrushes are capable of removing plaque and reducing bleeding on probing better than electric toothbrushes
