Objective: Effective removal of the dental plaque in the gingival sulcus and proper massage of the gingiva have been the important things to control the early stage of gingivitis, through the development of newly designed tooth-brush use. Methods: Three groups of materials were classified as experimental group for sulcus tooth-brush, positive control group as using the modified sulcus tooth-brush, and the control group as the plane tooth-brush as Buttler No. 209. Partial dentition model was produced as frontal and posterior portion by use of the extracted teeth on Molar teeth and upper anterior teeth on the dental plaster covered with the latex typed and open and close typed artificial gingiva. 10 times back and forth movement tooth-brushing was performed to all groups of the dental models, painted with the artificial plaque and plaque dying on the tooth surface and in the gingival sulcus, by use of the automatic tooth-brushing machine. The residual amounts of the artificial plaque was calculated and estimate the relative amounts of the removal of the artificial plaque in the dental plaque on each group, and compared them each others.Results: The clearance area of the artificial plaque in the gingival sulcus area was more in experimental group or positive control group than that of the control group at all portions of the tooth both in anterior and posterior teeth.Conclusion: Sulcus cleansing U-shaped tooth-brush was recommended to use for the Bass technique tooth-brushing in order to cleansing the dental plaque.
