Abstract
The effect of toothbrushing speed on toothbrushing pressures was evaluated during five tootbrushing procedures.
Five different kinds of toothbrushing methods (Scrubbing, Roll, Fones, Horizontal, and Vertical) were carried out with one kind of toothbrush (Perio-M). For each toothbrushing method, three different rates of brushing stroke (High speed, Standard speed, and Slow speed) were performed. A specifically designed microtransducer was set on a temporary resin crown to measure the brushing pressure exerted on the buccal surface of upper first molar.
The subjects were 9 males and 1 female consisted of dental students and dental staffs of school of Periodontics and Endodontics.
Also, integrated toothbrushing pressures per stroke and per second applied on the buccal surface of upper first molar of a plastic jaw model which corresponded to the work load were recorded with a integrator.
The subjects were 5 males and 2 females. Three different kinds of toothbrushing methods (Scrubbing, Fones, and Horizontal) were carried out with one kind of toothbrush (Perio-M).
The results obtained were as follows:
(1) The mean toothbrushing pressure of standard speed was significantly higher than the other two brushing rates for each toothbrushing procedure.
(2) For Scrubbing and Horizontal method, integrated brushing pressure per stroke and per second had a tendency to show higher value in Standard speed compared with the other two rates.
Similar trend was not found in Fones method.
