![]() Probing depth scores followed a similar pattern, with the Sonicare showing a mean reduction of 0.84 mm (15.8%) from baseline at 6 months, and Braun showing a 0.39 mm (7.2%) reduction (p = 0.002). The percentage reduction in inflammation from baseline at 6 months was 31.9% for Sonicare and 18.1% for Braun. Gingival inflammation also decreased in both groups over the 6-month period, but the Sonicare group showed significantly superior PBS scores at 4 months (t-test p = 0.002) and 6 months (p = 0.005). Interproximal plaque scores also improved in both groups with time, and the mean differential Sonicare post-brushing score was significantly better than the Braun at the 6-month visit (t-test p = 0.039). The mean overall plaque scores improved in both the Sonicare and the Braun groups at each of the follow-up visits. All measurements were recorded at baseline, 2, 4 and 6 months. Probing depths and attachment levels were determined using a manual North Carolina probe. Gingival inflammation was determined by the Papillary Bleeding Score (PBS) of Loesche. Plaque was scored using the Turesky, Gilmore and Glickman Index. ![]() The Sonicare and Braun groups were equally matched for plaque scores, and balanced for age, race and gender. Sixty-six adults with early-moderate periodontitis (5-7 mm Pd in at least two quadrants) entered the study, and 54 completed the entire study. A sonic electric toothbrush (Sonicare) and an oscillating/rotating electric brush (Braun Oral-B) were compared for efficacy in removing supragingival plaque, reducing gingival inflammation, reducing probing pocket depth (Pd) and improving probing attachment levels (PAL) in a 6-month, single-blind clinical trial. ![]()
