This study was undertaken to assess the efficacy of electric toothbrushes in bacterial plaque removal. These brushing times were longer than 3 minutes, which was previously considered to be the standard time. When the brushing was performed for an arbitrary time, plaque removing efficacy was 10-15% higher than that of 3 min. Differences were noted on the lingual and interproximal surfaces, both thought to be important in plaque control. These results show that longer brushing times than 3 min are recommendable.Furthermore, the subjects were divided into two groups on the basis of differences in technical ability to use a manual toothbrush. Efficiencies in removing plaque with the electric toothbrushes were then compared.Plaque removal in both groups, the high technical skill group and the low technical skill group, was
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
