Models of the upper and lower dental arches of 125 Chinese children in Taiwan with acceptable normal permanent dentition were surveyed in order to understand the developmental grades of dental traits from the viewpoint of dental anthropology. Developmental grades of dental traits were classified, calculated, statistically analysed by x2 test and results were summarized. Upper anterior teeth showed high frequency of shovel form; upper lateral incisors showed less tendency of regression. Interstitial cusp, lingual cusp, paracusp, central prominence and occlusal groove of lower premolars developed prominently. Upper molars showed low frequency of Carabelli cusps. Hypocone of upper second molars showed strong tendency of regression, but metacone had low regression tendency and a strong degree of compression. Compared to Japanese, Central American and South American Indians and Caucasians, the development of dental traits of Chinese in Taiwan was more similar to that of Japanese than to others. The characteristics of dental trait of Chinese in Taiwan and Japanese also showed greater similarity to Central and South American Indians than to Caucasians.
为了从牙人类学的角度了解牙齿性状的发育等级，对台湾125名具有可接受的正常恒牙列的中国儿童的上下牙弓模型进行了调查。对牙齿性状的发育等级进行分类、计算，采用x2检验进行统计学分析，并总结结果。上颌前牙铲形出现频率高；上颌侧切牙退化趋势较小。下颌前磨牙的间隙尖、舌侧尖、副尖、中央隆突和咬合沟发育明显。上颌磨牙卡氏尖出现频率低。上颌第二磨牙的次尖退化趋势强烈，但近中尖退化趋势低且压缩程度强。与日本人、中美洲和南美洲印第安人和高加索人相比，台湾中国人牙齿性状的发育与日本人更相似，而与其他人种不同。台湾中国人和日本人的牙齿性状特征与中美洲和南美洲印第安人也比与高加索人更相似。
