The aim of this study was to carry out the comparative analysis of the brushing force following various brushing techniques bytoothbrush mounted pressure sensing unit. The study group consisted of 10 dental hygienist participants. The brushing forces (onbuccal area of each first molar) were monitored on 8 different kinds of brushing techniques; Fones, Bass, Rolling, Scrub, Charters,stillman, Modified bass and Modified stillman. In Bass, Charters, Fones and Scrub method, force distributions showed a small gapof maximum and minimum value (Max/Min) while a big difference was noted in Modified bass, Modified stillman, Rolling and Stillmanmethods. Especially, the biggest difference of Max/Min value was observed in the area of lower left first molar. In conclusion, highlydelicate manual skill is needed in showing big error range of force distribution. It means that careful force needs to be focused duringtoothbrushing instruction when a delicate manual skill was carried out.
