A comparative clinical investigation of a novel toothbrush designed to enhance plaque removal efficacy.

Abstract

All toothbrushes in the seven studies significantly reduced levels of plaque from their pre-brushing values and were found to be safe with no evidence of oral soft tissue trauma. In each of the studies, the CrossAction was found to be significantly (P < 0.05) more effective than the comparison brush for whole mouth plaque scores, as well as for plaque scores at the gingival margin and proximal surfaces. Advantages in favor of the CrossAction ranged from 9.8% to 23.2% for whole mouth plaque, from 5.3% to 20.6% for the gingival margin and from 12.8% to 24.5% for proximal surfaces. It was concluded that the novel brush head design of the CrossAction toothbrush provides enhanced plaque removal, especially from proximal surfaces, and that this toothbrush is significantly more effective than all seven toothbrushes tested.
