 note = {application/pdf, Using 30 second-year students of the Matsumoto Dental College, School of Dental Hygiene as subjects, we performed investigations on toothbrush filament shape changes while using 4 test toothbrushes and 4 different brushing techniques over 2 week periods. Also, observation by scanning electron microscopy was done for the toothbrush which yielded the best plaque removal. The results were as follows: 1. The edge of the brush filament was worn almost rectangularly along the longitudinal axis after 2 weeks of using the Bass and scrub techniques. 2. The filament edge tended to become sharper with the rolling and modified Stillman techniques. The round-cut and moving area of the toothbrush body were worn significantly using the rolling and modified Stillman techniques. 3. The toothbrush filaments with every brushing technique were worn significantly. Deep ditches, scratches and peeling were frequently observed with the rolling and modified Stillman techniques.},
