Abstract

Studies were made of 15 women 18-22 years of age having a daily tooth cleaning habit with the rolling method. Each surface of the six blocks of the dental arch was brushed for 10, 15, 20 and 30 seconds; measurements were made of brushing force, brushing strokes, and plaque removal effect on each surface; the relations between the time required for brushing and plaque removal effect, the brushing force and the number of brushing strokes, between the brushing force and the brushing strokes, and the plaque removal effect during brushing, in an effort to clarify the significance of the time required for brushing in reference to brushing strokes and plaque removal effect with the following results:<BR>1) Increase of brushing time from 10 to 15 and then to 20 seconds increased brushing force and brushing strokes with an increase of plaque removal effect.<BR>But the increase from 20 to 30 seconds did not result in an increase of the plaque removal effect.<BR>2) A rate of increase in plaque removal effect accompanying an increase of brushing time showed no difference between the upper and lower jaws. But the increase from 15 to 20 seconds resulted in more increase in the labial and buccal surfaces than in the lingual surface.<BR>3) It was found that the plaque removal effect was marked in the labial and lingual surfaces of the anterior teeth in the upper and lower jaws, and very slight in the lingual surface irrespective of the length of brushing time.<BR>Thus, it was revealed that an optimal length of brushing time with a manual toothbrush following the rolling method for the tooth surfaces in one block proved to be 20 seconds, an optimal brushing force being 650-800g, and an optimal number of brushing strokes 30-35/20 sec.<BR>The data presently obtained of brushing time and the number of brushing strokes are to be recommend for those who give instruction in toothbrushing.
