Biological apatite (BAp) crystal forms crystallographic texture depending on the anatomical site, thereby optimizes mechanical functions. Our study revealed that in mandible the BAp c-axis orientation structure was formed in response to the stresses for sustaining the mandible and biting which are mainly applied in the mesiodistal and biting directions, respectively. Particularly, the local region immediately beneath the teeth root which is directly subjected by biting stress, showed a complicated BAp orientation distribution. The present study is aimed to discuss the formation of such anisotropic orientation structure of BAp found in mandible by focusing on the osteocyte behavior as a mechanosensory cell for detecting locally-applied anisotropic stresses.
