The toothbrushing pressures applied to the tooth surfaces through toothbrushes during toothbrushing procedures were determined by means of a specifically designed micro transducer. Five different kinds of toothbrushng methods (Scrubbing, Roll, Fones, Horizontal, and Vertical) were carried out with four different toothbrushes (Py-co-Pay softex 3 with 0.15mm. nylon bristle in diameter, Perio-S with 0.23mm. nylon bristle, Perio-M with 0.33mm. nylon bristle, and Perio-H with 0.40mm.). This study was completed by 22 subjects, 14 males and 8 females. These subjects were consisted of dental students, dental hygienists and dental staffs of school of Periodontics and Endodontics. A micro transducer was set in a temporary resin crown to measure the brushing pressures exerted on the buccal tooth surfaces of the upper first molars. Before measuring the toothbrushing pressures applied to the human tooth surfaces, the buccal tooth surfaces of the maxillary right first molars of the plastic jaw model were brushed and then the toothbrushing pressures were determined. A comparative study of the toothbrushing pressures obtained by a micro transducer and the toothbrushing forces gained by a straingauge were performed in this case also. The results varied with the toothbrushing methods and the toothbrushes. The results of this study were as follows. (1) Significantly greater mean maximum pressures were obtained during every toothbrushing procedure except Roll method as increasing a diameter of toothbrush bristle. (2) The toothbrushing pressures of Scrubbing method and Horizontal method were significantly greater than the other toothbrushing methods. (3) The toothbrushing pressures obtained by a transducer had a general tendency of a greater variation as compared to the toothbrushing forces gained by a straingauge.
