This study aimed to compare the rates of plaque removal from artificial tooth surfaces after brushing with a fixed orthodontic bracket electric toothbrush, an electric toothbrush, and a manual toothbrush to improve the success rate of orthodontic treatment by effectively managing oral care of orthodontic patients. A tooth model with fixed orthodontic brackets was stained with an artificial plaque disclosing agent in an occlusal state and washed twice with water. The amount of the disclosing agent remaining on the tooth surfaces after brushing was examined, on the basis of which the amount of plaque on the tooth surfaces was calculated using O’Leary index. Significance was set at p＜0.05. There was a statistically significant between-group difference in group-difference in the amount of the disclosing agent that remained on the tooth surfaces after brushing between with toothbrushes, the three types of toothbrushes, with an electric toothbrushes and manual toothbrushes after tooth brushing for brackets, with an F-statistic value of value of 5.037 for the mean difference of among the three groups and a significance of p-value of 0.001 and a significance level of 0.05. Electric toothbrushes are more effective than manual toothbrushes in removing dental plaque and controlling gingivitis.
