Research Abstract

Biological apatite (BAp) crystallite c-axis alignment is known to be a factor in the mechanical function of bone. This study aimed to elucidate the relationship between BAp crystallite alignment and Young's modulus in the alveolar area and base of the mandible area in human mandible cortical bone. A microbeam X-ray diffraction system was used to determine BAp crystallite alignment along the mesiodistal direction (longitudinal axis). Young's modulus along the mesiodistal direction in the same sites was also measured with nanoindentation, and the relationship between BAp crystallite alignment and Young's modulus was examined.
The present study suggests a close relationship between BAp crystallite alignment and Young's modulus, suggesting the importance of determining BAp crystallite alignment when evaluating bone strength. Determination of BAp crystallite alignment at first molar in the human mandible may also be useful in examining the effects of occlusal force.
