The dental remains of ten adult chimpanzees from Gombe National Park, Tanzania, were examined for enamel attrition, caries, abscesses, periodontal disease, and tooth loss. Age was the underlying factor in the development of dental pathology, in that enamel wear was present to some extent in all ten but was uniformly severe only in the three for whom estimated age at death was 39-43 years. In turn, enamel wear appears to have been the direct cause of abscess development, periodontal disease, and tooth loss. Periodontal disease was commonly expressed as alveolar resorption, particularly around the premolars and molars. This involvement was variable in all except the two youngest. Some interesting wear patterns were evident in the form of deep grooves in the upper incisors and dramatic notching of the lower canines. These patterns, and enamel attrition in general, were attributed to normal mastication and to various stripping activities. Only one carious lesion was observed, in a male with an estimated age of 26 years. An accurate assessment of the actual prevalence of caries was obscured by enamel wear and tooth loss in the older individuals.
对来自坦桑尼亚贡贝国家公园的10只成年黑猩猩的牙齿遗骸进行了检查，以观察牙釉质磨损、龋齿、脓肿、牙周疾病和牙齿脱落情况。年龄是牙齿病变发展的潜在因素，因为在所有10只黑猩猩中都有一定程度的牙釉质磨损，但只有在估计死亡年龄为39 - 43岁的3只黑猩猩中，牙釉质磨损才普遍严重。反过来，牙釉质磨损似乎是脓肿形成、牙周疾病和牙齿脱落的直接原因。牙周疾病通常表现为牙槽骨吸收，尤其是在前磨牙和磨牙周围。除了两只最年轻的黑猩猩外，其他黑猩猩的这种情况各不相同。一些有趣的磨损模式很明显，表现为上门牙的深沟和下犬齿的明显缺口。这些模式以及一般的牙釉质磨损，归因于正常咀嚼和各种剥脱活动。仅在一只估计年龄为26岁的雄性黑猩猩身上观察到一处龋损。由于老年个体存在牙釉质磨损和牙齿脱落，使得对龋齿实际患病率的准确评估变得模糊不清。
