1892年至1896年在西婆罗洲采集的野生猩猩标本收集到的Selenka猩猩标本，为研究自由放养灵长类动物的牙齿病理提供了极好的机会。对收集的223个头骨进行了牙齿状况分析，包括龋齿病变、局部感染(牙槽下和根尖周骨缺损)、水平骨丢失和生前牙齿丢失。对样本进行性别鉴定，分成三个广泛的年龄组，并进行比较，以确定与性别相关或与年龄相关的牙齿病理发生的差异。亚成体没有表现出任何牙病的证据。在青壮年组中，一人(2%)有根尖周骨缺损和水平骨质丢失的证据，另一人(2%)有两个相邻的近端间龋损。老年人患牙病的患病率要高得多，包括6%的龋病，26%的局部感染，23%的水平骨丢失，3%的死前牙齿脱落。年轻人和老年人之间患有牙科疾病的个体数量的差异在局部感染和水平骨丢失方面具有统计学意义。当按性别比较时，老年组显示，在所记录的所有类型的病变中，女性比男性有更高的牙科病理发生率，这些差异在局部感染和水平骨丢失方面具有统计学意义。考虑到饮食在牙齿疾病发展中的重要性，我们认为，性别的生态分离以及随后的饮食差异，可能是决定雌性猩猩牙齿病变发生率较高的重要因素。此外，当地生态因素的重要性，这可能会影响饮食模式，被认为是不同样本猩猩之间牙齿病理差异的潜在来源。
The Selenka orangutan collection obtained from 1892 to 1896 from wild-shot specimens in West Borneo, provides an excellent opportunity to examine dental pathology in free-ranging primates. Two hundred and twenty-three skulls from this collection were analyzed for dental conditions, including carious lesions, local infections (infra-alveolar and periapical osseous defects), horizontal bone loss, and premortem tooth loss. Specimens were sexed, divided into three broad age groups, and compared to ascertain sex-related or age-related differences in occurrence of dental pathology. None of the subadults displays any evidence of dental disease. One individual (2%) in the young adult group has a periapical osseous defect and evidence of horizontal bone loss, and another (2%) has two adjacent interproximal carious lesions. The old adults have a much higher prevalence of individuals afflicted with dental pathologies, including 6% carious lesions, 26% local infections, 23% horizontal bone loss, and 3% premortem tooth loss. The differences between the young and old adults in number of individuals afflicted with dental pathologies is statistically significant for local infections and horizontal bone loss. When compared by sex, the old adult group reveals that females have a higher occurrence of dental pathologies than males in all types of lesions recorded and these differences are statistically significant for local infections and horizontal bone loss. Considering the importance diet plays in the development of dental disease, it is suggested that ecological separation of the sexes, with the subsequent dietary differences, could be an important factor determining the higher prevalence of dental lesions observed in female orangutans. Additionally, the importance of local ecological factors, which may affect dietary patterns, are recognized as a potential source of variation in dental pathologies among different samples of orangutans.
