Abstract
The purpose of the present study was to clarify the phenotypic characteristics of the dental arch and palate in Korean subjects. We measured 209 pairs of maxillomandibular plaster models obtained from 105 male and 104 female Korean students (18-32 years old), and compared the findings in the present study with those in 12 other groups that we previously reported. A significant difference was observed between sexes in nearly all measurements among the Korean models. Further, both male and female Koreans demonstrated a significant difference in many measurement items from Jicaques models from Central America. We also studied the oral cavities of the Korean subjects using cluster analysis, a neighbor-joining method, and multidimensional scaling (MDS) for the purpose of elucidating anthropological orientation. We found that the male and female Korean subjects were more similar to Japanese and Taiwanese than to Balinese, Taiwan aboriginal people, or Jicaques.
