目的:了解新石器时期人髁突形态,探讨其与下颌角的关系。方法:选取保存基本完整的西安半坡遗址出土新石器时期(距今约6000年前)人下颌骨标本82例,左右侧髁突共122个,年龄20~60岁。采用数显游标卡尺及下颌骨测量器对下颌角及髁突进行测量,测量结果用SPSS 13.0进行统计分析。结果:不同下颌角角度各组中髁突形态分布有显著性差异(P<0.01);且随着下颌角角度的增加,异常型髁突比率存在增加趋势。结论:下颌角越大,表现为异常髁突形态的几率越大。为系统地研究人类髁突形态学演化积累数据资料。
Objective: To understand the shape of human condyle in Neolithic Age and to explore its relationship with mandibular angle. Methods: Eighty - two human mandibular specimens were excavated from the Neolithic Age (dating back about 6,000 years ago) in Xi’an Banpo Site with a complete preservation. A total of 122 condyles of right and left lateral muscles were obtained, ranging in age from 20 to 60 years old. The mandibular angle and mandibular angle were measured by digital vernier caliper and mandibular measuring instrument. The measurement results were analyzed by SPSS 13.0. Results: There was a significant difference in the distribution of condyles among different mandibular angles (P <0.01). With the increase of mandibular angle, the condylar ratio increased. Conclusion: The larger the mandibular angle, the greater the probability of abnormal condyles. To systematically study the evolution of human condyle morphological data accumulated data.
