Electric toothbrush vs. sonic toothbrush, the effectiveness on gingival inflammation: a randomized clinical trial

AIM: The aim of the study is to evaluate the efficacy of electric or sonic toothbrushes on periodontal inflammation. MATERIALS AND METHODS: A randomized, controlled, one-blind study was conducted. Patients in the test group used sonic toothbrushes (Sonicare FlexCare with ProResults brush head, HX6011, Philips Oral Healthcare Inc, Bothell, Wash), whereas those in the control group used electric toothbrushes (Oral B Professional Care Triumph 4000, Procter & Gamble, Cincinnati, Ohio). Periodontal status was recorded at baseline and 3 months. In total, 60 patients were recruited for the study at baseline. Plaque Index (PI) and Loe and Silness Gingival Index (GI) were used. Student's t- test repeated was used to compare the mean PI and GI scores obtained between the test and control groups at each time point. RESULTS: In total, 56 subjects completed the study. Significant differences were recorded between the two groups for periodontal parameters at 3 months. In addition, the indices of group Sonic were significantly reduced at 3 months compared to the Roto-oscillatory Group (P < .005). CONCLUSION: Sonic toothbrush reduced parameters of periodontal inflammation more effectively than the electric toothbrush.
