The purpose of this study was to evaluate the craniofacial and occlusal characteristics of the inhabitants in China.The material consisted of cephalograms, pantomograms, dental casts and anthropological measurements taken from 517 inhabitants : 416 Han Chinese in Beijing, Shanghai, Guangzhou and Changchun and 101 Mongolians in Hohhot. The data were compared among the above five regions and also with the Japanese data.The findings were summarized as follows :I. Craniofacial characteristics ;a) The Han Chinese and the the Mongolians showed brachycephaly.b) The inhabitants in Guangzhou showed a tendency of bimaxillary protrusion with a smaller facial height, and the inhabitants in Changchun showed a larger gonial angle with a larger facial height than those of the other regions.c) The Mongolians had a larger value of the saddle angle and of the bigonial breadth.d) Compared with the Japanese, their craniofacial complex was characterized by a larger facial angle, smaller mandibular plane angle and a smaller gonial angIe.e) The adults had a smaller gonial angle, a larger ramus inclination and a larger labial inclination of upper incisors, compared with the children.f) The male had a larger mandibular plane angle and a larger labial inclination of upper incisors, compared with the female.II. Occlusal characteristics ;a) The inhabitants in China had similar tendency in the dental arch form and in the dental trait frequency.b) The inhabitants in Beijing had larger mesiodistal crown-diameter of the anterior teeth than those in other regions.c) Compared with the Japanese, their teeth were characterized by a smaller mesiodistal crown-diameter (especially on the upper first molar), higher frequency of shovel-shape and lower frequency of Carabelli's tuberculum.d) The adults had shorter dental arch length compared with the children, and the male had wider dental arches compared with the female.

本研究的目的是评估中国居民的颅面和咬合特征。研究材料包括 517 名居民的头颅照片、断层照片、牙模和人类学测量数据：其中北京、上海、广州和长春的 416 名汉族人以及呼和浩特的 101 名蒙古人。对上述五个地区的数据进行了比较，并与日本的数据进行了比较。结果总结如下： 一．颅面特征;a) 汉族和蒙古族表现为短头畸形。b) 广州居民有双颌前突的倾向，面部高度较小，长春居民较其他地区表现出较大的角形角，面部高度较大。c) 蒙古族的鞍角和二角形值较大 d) 与日本人相比，他们的颅面复合体具有较大的面角、较小的下颌平面角和较小的角角。 e) 与儿童相比，成人的角角较小，升支倾角较大，上切牙唇倾角较大。 f) 男性较女性相比，下颌平面角较大，上切牙唇倾角较大。咬合特征；a) 中国居民在牙弓形态和牙齿特征频率方面具有相似的趋势。b) 北京居民的前牙近远中冠直径比其他地区的居民大。c) 与日本人相比，他们的牙齿的特点是近远中冠直径较小（特别是上颌第一磨牙），铲形频率较高，铲形频率较低。 Carabelli结节。d) 成人的牙弓长度比儿童短，男性的牙弓比女性宽。
