Abstract
The purpose of this study was to observed the endform of bristles, specification and physical characteristics of marketed toothbrushes. 23 toothbrushes were selected for this study. The specification of toothbrushes was examined with naked eyes, the endform of bristles with scanning electron microscopy and the deflecting force, abrasiveness with experimental estimation. The results were as following: 1. The size of brush head was 9-13(average 14.4)mm in widths, 25-42 (average 33.9)mm in lengths and the size of brushing plane was 6-10(average 8.3)mm in widths, 18-35(average 28.9)mm in lengths. 2. The lengths of bristles ranged from 9.0mm to 12.6mm (average 10.7mm) 3. The numbers of bristles per tuft were 22-93(average 40), and tufts were arranged in 3 or 4 rows. 4. The diameters of bristles ranged from 0.14mm to 0.26mm(average 0.197mm) and the most was 0.19mm in frequency. 5. There were 5 kinds endform of bristles: Round or half spherical, Sharp edge, Cut at right angle, Frayed to sharp spear, Elephant foot. Only 6 toothbrushes had round or half spherical bristles which was accepted ideal form 6. The deflecting forces of toothbrushes ranged from 103g to 172g. 100--130g was 9 brushes, 131-160g was 11 brushes and over 161g was 3 brushes. 7. There was unnoticeable amount of abrasion on the experimental abrasion plate at the level of 10-5 9
