Description

This study tested the effectiveness of several different types of electric toothbrush for removal of supra-gingival plaque. Five different types of electric toothbrush were used, and comparisons were made among the conditions and with manual toothbrushing. Ten adults (meanage 23.6 years) with normal dentition and healthy gingiva participated in this study. Plaque score before and after brushing (3 min.) were assessed.<BR>The rate of plaque removal of the counter rotational action powered toothbrush (INTERPLAK ®) was the highest among toothbrushes we tested. It showed better efficacy of plaque removal in the proximal and lingual areas.<BR>The round tuft reciprocating toothbrush (PLAKCONTROL ®) showed a higher rate of palque removal than manual toothbrushing, and the effect of plaque removal in the proximal area was superior to that of the manual toothbrush. Another electric toothbrush we tested showed almost the same or a higher rate of plaque removal than the manual toothbrush.<BR>In conclusion, several different types of electric toothbrush showed almost the same or higher effectiveness in plaque removal than manual toothbrushing. Our results indicate that toothbrushing with an electric toothbrush is considerably effective for supra-gingival plaque removal.
