选取沈阳市沈阳医学院附属医学院男68名，女82名，年龄16~18岁，采用亚利桑那州立大学牙科人类学系统进行检查。东北亚典型的Sinodonty和东南亚典型的Sundadonty的8个性状显示出相当大的差异。汉族的翅膀(UII)与Sundadonty的相似。汉族人的Cusp5(UMI)、Carabelli‘s特征(UMI)、Y型纹(LM2)和偏折皱纹(LMI)与Sinodonty相似。汉人铲(UI1)、四尖(LM2)和双铲(UII)介于两齿和两齿之间。北方中国-蒙古族与S、中国在13个性状上存在显著差异。犬远端副牙槽骨(UC)、舌尖变异(LP2)、偏折皱纹(LMI)与北方中国-蒙古族相似。汉族人的双铲、间断沟、尖牙内侧脊、牙冠、远中三角、尖牙尖均与S相似。汉族的牙齿结节(UI2)、下锥体(UM2)和尖端(Umi)位于北中国-蒙古国与S中国之间。分析表明，汉族的牙列具有华牙特征，与S、中国的牙列有较大的相似性，而不是与中国-蒙古族的牙列相似。
were taken from 68 male and 82 female students, 16 to 18 years of age, of the Paramedical School of Sheng Yang Medical College in Sheng Yang City, They were examined using the Arizona State University Dental Anthropology System. Eight traits show considerable differences between Sinodonty, which is typical of Northeast Asia, and Sundadonty, which is typical of Southeast Asia. Winging (UII) of Han were similar to those of Sundadonty. Cusp5 (UMI), Carabelli's trait (UMI), Y-groove pattern (LM 2), and deflecting wrinkle (LMI) of Han were similar to those of Sinodonty. Shoveling (UI 1), 4-cusp (LM2) and double shoveling (UII) of Han lie between Sinodonty and Sundadonty. Thirteen traits show considerable differences between N China-Mongolia and S China. Canine distal accessory ridge (UC), lingual cusp variation (LP2), and deflecting wrinkle (LMI) of Han were similar to those of N China-Mongolia. Double shoveling (UII), interruption groove (UI2), canine medial ridge (UC), odontome (U+LPI, 2), Carabelli's trait (UMI), distal trigonid crest (LMI), and cusp6 (LMI) of Han were similar to those of S China. Tubercuium dentale (UI2), hypocone (UM2), and cusp5 (UMI) of Han lie midway between N China-Mongolia and S China. This analysis indicates that the dentition of the Han is characteristic of Sinodonty, and bears greater resemblance to that of S China rather than to that of N China-Mongolia.
