Tooth enamel thickness is widely studied in primates and is important in differentiating taxa and in interpreting diet and feeding behavior. The objective of this study was to measure enamel thickness and discuss whether the results can be associated with different feeding patterns. Thirty-four syncraniums of , , and were subjected to cone beam computed tomographic (CBCT) scans, and the dental enamel was measured in different regions of the crown using the multiplanar reconstruction tool. The differences observed indicate that for many variables and teeth, showed significantly higher values compared to the other 2 species, with the exception of the cuspid region. Although the is a folivorous species, it showed thicker enamel for most of the variables. CBCT was efficient in performing the measurements, allowing analysis of the syncraniums.
牙釉质厚度在灵长类动物中被广泛研究，对于区分分类群和解释饮食和进食行为非常重要。本研究的目的是测量牙釉质厚度，并探讨其结果是否与不同的进食模式有关。34 个 、 和 的颅腔进行了锥形束计算机断层扫描（CBCT）扫描，并使用多平面重建工具测量了牙冠不同区域的牙釉质。观察到的差异表明，对于许多变量和牙齿，与其他 2 个物种相比， 表现出明显更高的值，除了尖牙区域。尽管 是一种食叶动物，但它在大多数变量中显示出更厚的牙釉质。CBCT 在进行测量方面非常有效，允许对颅腔进行分析。
