Purpose: To compare the clinical efficacy with respect to plaque removal of a battery-operated power toothbrush (Dr. Johns Spin Brush Classic) with two manual toothbrushes, a standard ADA flat trim reference brush and the Oral-B CrossAction toothbrush. Materials and Methods: Efficacy was evaluated in two independent studies using a randomized, single-use, cross-over design. Healthy adult subjects from a general population brushed their teeth for a timed 1 min and plaque was scored before and after brushing was completed. In Study 1 (Spin Brush vs. ADA toothbrush), plaque was scored using the modified Quigley and Hein Plaque Index, while in Study 2 (Spin Brush vs. CrossAction) plaque was scored using the Modified Navy Plaque Index. In addition, a hard and soft tissue examination was carried out before and after brushing to allow evaluation of safety. Results: In Study 1, both the ADA toothbrush and the Spin Brush significantly reduced levels of whole mouth and approximal plaque (P< 0.0005); however, the Spin Brush was not significantly more effective than the manual brush. Relative plaque reduction for the whole mouth was 35.6 ± 16.0% for the Spin Brush compared to 38.9 ± 14.9% for the manual toothbrush (P< 0.047), and, for the approximal surfaces, 32.7 ± 14.6% and 36.3 ± 13.7%, respectively (P= 0.024). In Study 2, both toothbrushes significantly reduced plaque levels (P< 0.0001), but, as for Study 1, the CrossAction manual toothbrush was more effective than the Spin Brush. For whole mouth, marginal and approximal sites, respectively, the Spin Brush reduced plaque by 54.3%, 43.5% and 62.0%, compared with 58.6%, 47,5% and 67.1% for the CrossAction toothbrush. The difference in favor of die CrossAction brush was statistically significant (P< 0.0055) for all areas. [ABSTRACT FROM AUTHOR] |
