中文摘要 | 本研究利用Vernier caliper (精密度為 0.05mm)來測量臺灣人恆齒長度,其結 果如下:(1)就上顎牙齒而言,中門齒平均長度為23.12mm;側門齒為21.89mm;犬齒為 25.90 mm;第一前臼齒為21.15 mm;第二前臼齒為21.21mm; 第一臼齒為19.89mm;第二 臼齒為19.55mm(2)就下顎牙齒而言,中門齒平均長度為19.33mm;側門齒為20.16 mm; 犬齒為24.68mm;第一前臼齒為21.79mm;第二前臼齒為21.28mm;第一臼齒為19.66mm; 第二臼齒為19.66mm。由以上結果得知臺灣人牙齒平均長度與日本人相近,但較白人或黑 人為短。 |
英文摘要 | The lengths of permanent teeth form Taiwanese were measured with Vernier caliper with an accuracy Of 0.05 mm in this study. The results were as follow as: (1) of the maxilla. The mean tooth length was 23.12mm in the central incisors, 21.89 mm in the lateral incisors, 25.90 mm in the canines, 21.15 mm in the first premolars, 21.21 mm in the second premolars, 19.89 mm in first molars and 19.55 mm in the second molars. (2) Of the mandible, the mean tooth length was 19.33 mm in the central incisors, 20.16 mm in the lateral incisors, 24.68 mm in the canines, 21.79 mm in the first premolars, 21.28 mm in the second premolars, 19.66 mm in the first molars and 19.66 mm in the second molars. The mean length obtained closely approximated to Japanese length, but seemed to be shorter than Caucasians or Negroes. |
