摘　　要：目的:通过对距今1100～1300年前古人牙齿形态的测量,了解当时的牙齿形态特征,以探寻牙齿形态演化趋势。方法:观察记录了62具陕西长安区出土1000年前人骨架的牙齿,共纳入631个。其中上颌328个,下颌303个。分别测量其冠长、牙冠横切面面积、冠宽、冠厚、颈宽、颈厚,并进行统计学分析。结果:报告了各牙位牙齿的冠长、牙冠横切面面积、冠宽、冠厚、颈宽、颈厚等数据。结论:通过对1000年前古人牙齿的形态学测量,为中国人牙齿形态研究积累一定的数据资料。AIM： To investigate the morphological information of the teeth of T＇ang dynasty about 1000 years ago, and to study the changes of teeth during human evolution. METHODS： Teeth of 62 human skulls excavated from the Changan county in Shaanxi Province about 1000 years ago were measured and recorded. Totally 631 teeth were observed, including 328 upper teeth and 303 lower teeth. Height of dental crown, crown areas of the tooth, breadth of the dental crown, thickness of the dental crown, breadth of the dental neck and thickness of the dental neck were measured and analyzed. RESULTS： For height of dental crown, crown areas of the tooth, breadth of the dental crown, thickness of the dental crown, breadth of the dental neck and thickness of the dental neck, the average results were reported. CONCLUSION： Through measuring the teeth of T＇ang dynasty about 1000 years ago, we collect data for study of the Chinese teeth morphology.
