Objective: In order to prove the effect of removing the plaque attached on the tooth surface and the dorsum of the tongue of dental patients equipped with orthodontic appliance, a clinical trial was conducted. 
Methods: Sixty adult volunteers who were equipped with a fixed type of orthodontic appliance participated in this study and they were divided into two groups: experimental group who were supplied with 360o round toothbrushes and control group who were provided with V shaped concave type bristle plane toothbrushes as routine type toothbrushes for the patients equipped with the orthodontic appliance. Simplified patient hygiene performance (S-PHP) index and tongue plaque index were measured 4 times: before this experiment, a week later, and 2 and 4 weeks later after this experiment, and the data were collected and compared between the experimental group and the control as time goes by. 
Results: S-PHP index and tongue plaque index decreased in experimental group after 2 and 4 weeks later, but this result wasn’t significantly meaningful between experimental group and the control (p<0.01). It revealed decreasing tendency of S-PHP and tongue plaque index in experimental group as time goes by (p<0.05). 
Conclusion: It was recommended to use 360o round head toothbrushes with a proper instruction for cleaning tooth surface and appliance in order to remove the dental plaque and tongue plaque effectively.
