The purpose of the study was to clinically evaluate & compare the efficacy of PM-TC Sonic® tooth brush & Oral-B® battery powered tooth brush in the reduction of established plaque, gingivitis & halitosis. 40 healthy volunteers were selected & randomly assigned into 2 groups; one group used PM-TC Sonic® tooth brush & the other group used Oral-B® battery powered tooth brush. PI, MGI, GBI & Halitosis grading were assessed at baseline, 15th day, 30th day, 45th day & 60th day. At the end of the study, reduction in PI, MGI, GBI were statistically highly significant during each interval for both the toothbrushes. For PM-TC Sonic® tooth brush the reduction in halitosis grading at 0-45 days interval was significant & at 0-60 day interval it was highly significant. For Oral-B® battery powered tooth brush the reduction in halitosis grading at 0-45 days interval was highly significant & at 0-60 days interval it was significant. The difference in reduction of clinical parameters between the two tooth brushes was statistically non significant. Both the tooth brushes used in this study were clinically effective in removing plaque, improving gingival health & reducing halitosis.
