The effectiveness of a musical toothbrush for dental plaque removal: a comparative study.

Background and Objectives: the purpose of this study was to clinically evaluate and compare the efficacy of Brush Buddies musical tooth brush and Colgate Smile tooth brush in the reduction of established plaque and gingivitis. Materials and Methods: for this study, 120 healthy kids (73 boys and 47 Girls) were selected. The subjects were randomly assigned into two groups by a second examiner; one group used Colgate Smile brush and the other group used Brush Buddies musical tooth brush. Plaque index (Quigley and Hein), Modified Gingival Index (Lobene and Associates) and Gingival Bleeding Index (Ainamo and Bay) were assessed at baseline, 30th day, 60th day, and 90th day. Results: all the baseline indices appeared to be well balanced. At the end of the study, reduction in plaque index, modified gingival index and gingival bleeding index were statistically highly significant during each interval for both the toothbrushes. For Brush Buddies musical tooth brush, the reduction in all clinical parameters were statistically significant for 30 days and 60 days interval, while nonsignificant at 90 days interval. Interpretation and Conclusion: both the tooth brushes used in this study were clinically effective in removing plaque, improving gingival health. Musical tooth brush is more effective initially but as the time period increases both tooth brushes give almost similar results.
