Comparisons of indentation (a) modulus and (b) viscosity between sham and OVX groups. The indentation modulus was marginally different at the inner regions of vertebral trabecular bone (VB, *; p=0.055) between sham and OVX groups while the indentation viscosity was significantly different at the mandibular cortical basal bone (CB, #; p<0.036) and at the marginal region of mandibular trabecular bone (TBM, ##; p<0.012), and marginally different at the inner regions of mandibular trabecular bone (TB, **; p=0.065). No significant difference was found at all other regions (p>0.1).
