Abstract
The purpose of this study was to evaluate the plaque removal effects of an electric interdental toothbrush and a conventional manual interdental toothbrush at the proximal surfaces of model teeth. The electric interdental toothbrush was composed of a main body with a motor that generated the vibrations and a PROSPEC® interdental toothbrush attachment. The manual interdental toothbrush did not vibrate. The mean plaque removal rate of the electric interdental toothbrush was 26% and 32% after 5 and 10 cleanings, respectively, and these removal rates were significantly higher(p<0.01)than those for the manual interdental toothbrush. Based on these findings, it is concluded that the plaque removal effect of the electric interdental toothbrush was greater than that of the manual interdental toothbrush.
