Objective: Artificial plaque removal effect was checked after development of new design as 360 degree round head toothbrush.Methods: Lux360 Molar toothbrush was selected for experimental group and the plane toothbrush with similar bristle size for the control. Toothbrushing for 5 times was done by use of the automatic toothbrushing machine for back and forth movement equipped with the toothbrush head on the test unit. The plaque removal effect was checked by estimation of the image for remnant color area by use of the image analysis of the computer program and compared the rate of the remnant area of the disclosing agent. Results: Artificial plaque removal effects were more in experimental group than those of the control group, both at anterior and posterior areas (p<0.05), except in the area with the orthodontic bracket adapted model (p>0.05). By brushing with horizontal or vertical movement. Conclusion: Degree of 360 round head toothbrush was effective for plaque removal in vitro experiment and recommended to use for cleansing the tooth surface.
