Male baboons use their sharp upper canines in aggressive interactions. These teeth are sharpened against specialized lower third premolars. The honing premolar is protected against wear by having very thick enamel and the upper canine having very thin enamel, not by structural or mineral differences between the two enamels. Evidence is presented which shows the interactions of enamel ultrastructure and both dentin and enamel wear in canine sharpening.
雄性狒狒在攻击性互动中会使用它们尖锐的上犬齿。这些牙齿会与专门的下第三前磨牙相互摩擦以变得锋利。研磨前磨牙通过拥有非常厚的釉质来防止磨损，而上犬齿的釉质非常薄，并非通过两种釉质之间的结构或矿物质差异来保护。文中给出的证据表明了在犬齿磨利过程中釉质超微结构与牙本质及釉质磨损之间的相互作用。
