Evaluation of a new multi-directional power toothbrush versus a marketed sonic toothbrush on plaque and gingivitis efficacy.

Abstract

All 130 subjects completing the trial were evaluable. Both the novel multi-directional power and sonic control brushes produced significant mean reductions in gingivitis, gingival bleeding and plaque (whole mouth and region-specific) at Week 4 in comparison to baseline (P < 0.001). The new multi-directional power brush performed statistically significantly better (P < or = 0.001) in all efficacy measures after 4 weeks ofbrushing, providing superior adjusted mean relative reduction benefits versus the sonic control brush of 48% for MGI, 52% for GBI, 26% for whole mouth RMNPI, 58% for gingival margin RMNPI plaque, and 33% for interproximal (approximal) RMNPI plaque. Both toothbrushes were well-tolerated.
