牙齿长期以来一直被用作灵长类动物生态的指标。早期的工作集中在牙齿形态、饮食和行为之间的联系，近年来强调牙齿磨损、微观结构、发育和生物地球化学，以了解灵长类动物的生态学。我们对马达加斯加贝扎马哈法利特别保护区的狐猴卡塔进行的研究揭示了一种不寻常的牙齿严重磨损和频繁牙齿脱落的模式，这主要是由于食用了这些灵长类动物的牙齿不适应的备用食物的结果。只有结合我们的专业领域（牙科解剖学 [FC] 和灵长类动物生态学 [MS]）才能解释这些数据。通过整合两个研究领域的理论、方法和应用方面，我们采用了“牙科生态学”一词，定义为对牙齿如何响应环境的广泛研究。具体来说，我们将牙齿生态学视为一种解释框架，使用牙齿作为理解有机体生态学的工具，它建立在早期工作的基础上，但创造了解剖学和生态学的新综合，而这只有在对活体灵长类动物有详细了解的情况下才有可能实现。该框架包括（1）在摄食生态、行为、栖息地变化和人为变化的背景下识别牙齿病理和牙齿使用磨损的模式，（2）评估牙齿发育和生物地球化学信号可以反映栖息地、环境变化和/或压力的方式，以及（3）牙齿微观结构和宏观形态如何适应并反映摄食生态。在这里，我们定义了牙科生态学，对这一观点的发展进行了简短的总结，并将我们的新工作置于这一背景下。 Am J Phys Anthropol 148:163170, 2012。(c) 2012 Wiley periodicals, Inc.
Teeth have long been used as indicators of primate ecology. Early work focused on the links between dental morphology, diet, and behavior, with more recent years emphasizing dental wear, microstructure, development, and biogeochemistry, to understand primate ecology. Our study of Lemur catta at the Beza Mahafaly Special Reserve, Madagascar, has revealed an unusual pattern of severe tooth wear and frequent tooth loss, primarily the result of consuming a fallback food for which these primates are not dentally adapted. Interpreting these data was only possible by combining our areas of expertise (dental anatomy [FC] and primate ecology [MS]). By integrating theoretical, methodological, and applied aspects of both areas of research, we adopted the term dental ecologydefined as the broad study of how teeth respond to the environment. Specifically, we view dental ecology as an interpretive framework using teeth as a vehicle for understanding an organism's ecology, which builds upon earlier work, but creates a new synthesis of anatomy and ecology that is only possible with detailed knowledge of living primates. This framework includes (1) identifying patterns of dental pathology and tooth use-wear, within the context of feeding ecology, behavior, habitat variation, and anthropogenic change, (2) assessing ways in which dental development and biogeochemical signals can reflect habitat, environmental change and/or stress, and (3) how dental microstructure and macro-morphology are adapted to, and reflect feeding ecology. Here we define dental ecology, provide a short summary of the development of this perspective, and place our new work into this context. Am J Phys Anthropol 148:163170, 2012.
