| Abstract Scope |
The enamel of mammalian teeth must resist wear and fracture under the range of bite forces that encompass oral functions. Damage tolerance is key. A principal contribution to the fracture resistance of this tissue is enamel rod decussation, i.e. an interesting pattern of weaving that give rise to the Hunter Schreger’s bands evident in white-light microscopy of this tissue. Due to its importance to lifelong health, enamel rod decussation in human teeth has been studied in some detail. However, the bite forces of humans are rather low with respect to that of other mammals. Our group has been exploring the decussation patterns in teeth of mammals in search of correlations of the enamel microstructure and function. This talk will present new results on the decussation patterns in teeth of various mammals representing a large range of bite forces, the spatial distribution in mechanical behavior, and the fracture resistance of enamel. |
