8-week evaluation of anti-plaque and anti-gingivitis benefits of a unique multi-directional power toothbrush versus a sonic control toothbrush.

Abstract

A total of 128 evaluable subjects completed the study. After 8 weeks of brushing, both test toothbrushes provided statistically significant reductions compared to baseline in mean whole mouth MGI and GBI, and in RMNPI whole mouth and interproximal (approximal) sites (P < 0.001). The novel multi-directional power brush consistently produced significantly superior anti-gingivitis and anti-plaque reductions relative to pre-treatment versus the sonic control brush: the Week 8 adjusted mean relative reductions were 30% and 29% greater for whole mouth MGI and GBI, respectively (P < 0.001); and were 44% and 77% greater for the RMNPI whole mouth and interproximal regions, respectively (P < or = 0.003). Both toothbrushes were well-tolerated.
