| Abstract Scope |
Tooth enamel is remarkably damage tolerant. A beamline study was conducted to elucidate and compare the microstructure of enamel from various mammalian species to inform the synthesis of strong, fracture-resistant bioinspired materials. X-ray micro computed tomography (micro-CT) was performed at Beamline 2-BM of the Advanced Photon Source and Beamline 8.3.2 of the Advanced Light Source to elucidate the microstructural assembly of the rods and characterize the decussation bands. X-ray synchrotron tomography offers several advantages for imaging mammalian tooth enamel compared to traditional laboratory-based imaging techniques, including high-resolution 3D imaging and phase contrast enhancement. Species including lion, wolf, wild African dog, snow leopard, otter, bear, and primate were imaged. The phase-contrast micro-CT imaging with less than 2 µm resolution revealed new details across the species and this presentation will discuss key findings. |
