Abstract
Purpose of this study was to obtain basic anatomical data for developing optimal toothbrush which is appropriate for Koreans
Dental study models were examined by measuring the length from labial midline of deciduous canine to distal surface of deciduous second molar, from labial midline of permanent canine to distal surface of second premolar, from mesial surface permanent first molar to distal surface of permanent second molar, cervico-incisal length of deciduous central incisor, cervico-incisal length of permanent central incisor, from mesiobuccal cusp of deciduous maxillary second molar to mesiolingual cusp of deciduous maxillary second molar, from mesiobuccal cusp of permanent maxillary first molar to mesiolingual cusp of permanent maxillary first molar, from distolinual cusp of deciduous mandibular second molar to mesiolingual cusp of deciduous mandibular second molar, from mesiobuccal cusp of permanent mandibular first molar to mesiolingual cusp of permanent mandiblar second molar in 241 subjects. And the width of right hand was examined on each subjects by measuring the length of landmarks which were selected in handwrist X-ray film.
Commercial, toothbrushes sold in Korea were collected and the head length, head width, bristle length and handle length of toothbrushes were measured.
The obtained results were as follows ;
1. The head length of toothbrush which were appropriate for Koreans aged 6 to 8 was less than 21.8 mm. The head width length of toothbrush which were appropriate for Koreans aged 6 to 8 was less than 8.4 mm, The bristle length of toothbrush which were appropriate for Koreans aged 6 to 8 was more than 5.7 mm. The handle length of toothbrush which were appropriate for Koreans aged 6 to 8 was more than 84.3 mm,
2. The head length of toothbrush which were appropriate for Koreans aged 9 to 11 was less than 20.4 mm.
The head width length of toothbrush which were appropriate for Koreans aged 9 to 11 was less than 8.4 mm, The bristle length of toothbrush which were appropriate for Koreans aged 9 to 11 was more than 9.3 mm, The handle length of toothbrush which were appropriate for Koreans aged 9 to 11 was more than 95.2 mm.
3. The head length of toothbrush which were appropriate for Koreans aged over 12 was less than 25.5 mm. The head width length of toothbrush which were appropriate for Koreans aged over 12 was less than 8.6 mm. The bristle length of toothbrush which were appropriate for Koreans aged over 12 was more than 9.6 mm, The handle length of toothbrush which were appropriate for Koreans aged over 12 was more than 101.1 mm,
4. Some toothbrush for children was not appropriate because of its big size, and toothbrush sells in Korea must be diversified for appropriate selection.
