A Clinical Comparison of Plaque Removal Performance of Three Manual Toothbrushes

M J Deasy et al. J Clin Dent.

Abstract

A clinical study was performed to evaluate and compare the plaque-removal performance of a recently introduced, computer-designed manual toothbrush with that of two commercially available products; the Oral-B 40 and the Reach Full-Head soft toothbrushes. Seventy-five adult male and female subjects participated, each refraining from toothbrushing for twenty-four hours. Plaque was scored according to the Rustogi, et al. refinement of the Modified Navy Plaque Index. Following screening, the subjects were divided into three balanced groups on the basis of initial plaque scores. Each group, in an alternate weekly cross-over design, used each of the three toothbrushes. At Visit 1, each group, having refrained from toothbrushing for twenty-four hours, was evaluated for plaque before brushing for sixty seconds with the assigned toothbrush, after which plaque was again scored. At Visit 2 one week later, the same procedure was followed except for the assignment of a different toothbrush. The same procedure was employed for Visit 3. On completion of the study, the data were subjected to statistical analyses which indicated that the Colgate Precision Full Head soft toothbrush removed significantly more plaque than either of the other two toothbrushes.
