一项对猕猴群体中30名个体牙齿磨损的变量和模式的研究表明，考虑年龄和性别对于理解磨牙咬合平面的磨损程度差异至关重要。随着年龄的增长，这种非人灵长类动物的初始形态特征通过釉质的逐渐侵蚀而消失。两种性别的磨损梯度与PM 1-M3不同。看来，有一个功能之间的关系程度的咬合面磨损和磨损程度的犬齿，女性表现出更大程度的磨损变化相对于男性的年龄相当，因为最初的差异，犬齿的长度和健壮性，由于性别二型性。看来，有一个直接的关系，咬合磨损平面的变化和磨损程度的犬齿，与先进的差异磨损出现在个人中，多年的上颌犬齿珩磨，犬齿损伤，咀嚼的正常磨损已减少尺寸的未磨损的永久犬齿。本研究中的其他考虑因素包括下颌乳第一磨牙的珩磨功能和磨牙牙尖高度相对于犬齿功能。
A study of variables and patterns in dental wear among 30 individuals in a colony ofMacaca nemestrinashows that consideration of age and sex are crucial for understanding differential wear degrees on molar occlusal planes. With advanced age, this species of non‐human primate undergoes obliteration of initial morphological characteristics through the gradual erosion of enamel. Wear gradients are differential from PM1‐M3 in both sexes. It appears that there is a functional relationship between degrees of occlusal plane wear and the degree of wear on the canines, and that females show a greater degree of wear changes relative to males of equivalent age because of initial differences in canine length and robusticity due to sexual dimorphism. It appears that there is a direct relationship between occlusal wear plane changes and the degree of wear on the canines, with advanced differential wear showing up in individuals in whom years of maxillary canine honing, canine damage, and the normal wear of mastication has reduced dimensions of unworn permanent canines. Other considerations included in this study are the honing functions of the deciduous first mandibular molars and molar cusp height relative to canine function.
