Efficacy of removal of sucrose-supplemented interproximal plaque by electric toothbrushes in an in vitro model

Abstract

Electric toothbrushes were evaluated using a model of plaque removal by fluid shear forces. Sucrose supplementation during plaque development did not affect the removal of bacteria from biofilm exposed to low-energy shear but did increase their resistance to high-energy shear. The toothbrush supplying high-energy shear forces removed significantly more viable bacteria.

Spatial arrangement of the teeth, toothbrush, and biofilm-covered HA discs (plan view). The bristles of the toothbrushes were separated from the HA disks by a minimum distance of 2 mm, and the brushing solution did not submerge the disks. The thickness of the biofilm was 200 μm.
