Tooth enamel is amongst the most highly mineralized tissues to be studied by materials scientists and engineers. While the enamel of human teeth has received substantial attention, relatively few studies have evaluated the enamel of other mammals. In addition, a comparison of enamel from teeth enrolled in relatively low and high bite forces of mastication has not been reported. In this investigation we compare the enamel of teeth from the brown hyena (Hyaena brunnea) and neotropical fruit bat (Artibeus) in terms of the microstructure, chemical composition and hardness. A comparison of the microstructure showed that the enamel rod distribution in the teeth of fruit bats is absent of apparent decussation, whereas that of the hyena tooth exhibits regions of very complicated decussation. Additional characteristics of the enamel in both teeth including the differences in chemical composition and hardness distribution are presented.
