【摘要】：作为一种特殊形式的牙齿磨耗与使用痕迹,牙齿崩裂与古人类及古代人群食物质地、获取与制作食物方式、某些行为活动、生活习俗密切相关。然而,迄今对人类牙齿崩裂的关注程度及开展的研究还不多,尤其缺乏更新世晚期人类牙齿崩裂出现率和表现特点方面的数据。本文对发现于贵州兴义猫猫洞的更新世晚期人类牙齿釉质崩裂痕迹大小、出现率、表现特点进行了观测分析。研究发现,附连在3件猫猫洞人类下颌骨上的牙齿具有明显的釉质崩裂现象,出现率与生活环境恶劣的狩猎-采集人群接近。值得注意的是猫猫洞人类牙齿釉质崩裂出现在几乎所有臼齿的咬合面边缘。作者认为出现在猫猫洞人类臼齿的釉质崩裂是由于强力咀嚼和研磨坚硬食物所致,推测当时人类的食物粗糙,坚硬,富含颗粒(如坚果、种子等)。在猫猫洞下颌骨上观察到的波及几乎全部牙齿的牙周病也为猫猫洞人类严酷生活环境和粗糙食物的推测提供了一定程度的支持。此外,几乎所有具有釉质崩裂的臼齿都呈现大小不等的多发性的釉质崩裂痕迹的表现特点提示猫猫洞人类长时间大量食用这种粗糙、坚硬食物。
[Abstract]:As a special form of tooth wear and use marks, tooth disintegration is closely related to the food texture of ancient people and ancient people, the way of obtaining and making food, some behavior and activities, and living customs. However, so far, there is not much attention and research on human tooth disintegrating, especially lack of data on the occurrence rate and characteristics of human tooth collapse in late Pleistocene. In this paper, the size, occurrence rate and characteristics of tooth enamel disintegration in late Pleistocene human tooth were observed and analyzed in the cat cave of Xingyi, Guizhou. It was found that the teeth attached to the mandible of three cat caverns had obvious enamel disintegration, and the occurrence rate was close to that of hunter-gatherers living in a bad environment. It is worth noting that the human tooth enamel cleavage occurs at the edge of the occlusal surface of almost all molars in the Cat Cave. The authors believe that the breakdown of enamel in human molars in cat caverns is caused by strong chewing and grinding of hard foods. It is assumed that human food at that time was rough, hard, and rich in particles (such as nuts, seeds, etc.). Periodontal disease, which was observed on the mandible of the cat cave, also provides some support for the prediction of the harsh living environment and rough food in the cat cave. In addition, almost all molars with enamel disintegration present multiple enamel disintegration traces of varying sizes, suggesting that cat caverns consume this coarse, hard food in large quantities for a long time.
