After toothbrushing with three-sided electric toothbrush, general electric toothbrush, manual toothbrush, the change in plaque is examined. And then, the effect of removing the dental plaque with the developed three-sided electric toothbrush is evaluated. After 30 times toothbrushing with the three types of toothbrushes respectively, three-sided electric toothbrush, a general electric toothbrush, and a manual toothbrush, the changes in the tooth surface plaque PHP-index and the differences in the occlusal state were examined. The mean standard deviation was analyzed to see the changes in the oral environment management ability index after brushing with a coloring agent. Each average figure of manual toothbrushes, general electric toothbrushes, and three-sided electric toothbrushes was 2.44, 1.95, and 1.19 in order. It was found that the three-sided electric toothbrush, which wipes occlusal surface more than general electric toothbrushes and manual toothbrushes, was more effective for removing tooth surface plaque.
