A comparative clinical study of extrinsic tooth stain removal with two electric toothbrushes [Braun D7 and D9] and a manual brush.

Abstract

Analysis of the results showed that the two electric toothbrushes were significantly better at removing stain than the manual toothbrush. In addition, the D9 was consistently more effective than the D7, with the difference with respect to stain area achieving statistical significance (P < 0.05) after 2 minute's brushing. All three brushes were found to be safe, and there was no evidence of any soft or hard tissue abrasion. It was concluded that the oscillating/rotating electric toothbrushes were more effective in removing extrinsic dental stain than a manual brush, and that compared with the D7, the newly designed Braun Oral-B Ultra Plaque Remover has an increased potential for stain removal.
