Table 3. Morphometric indices corresponding to the trabecular bone microarchitecture and cortical bone morphology in the mandibles of the control and ovariectomized groups.
| Bone | ROI | Parameter | Unit | Control(Median±IQR) | ovariectomized (Median±IQR) | P† |
|---|---|---|---|---|---|---|
| Mandible | Trabecular bone parameter | BV/TV | % | 51.704±6.253 | 38.486±9.111 | 0.004* |
| TbTh | mm | 0.239±0.028 | 0.193±0.070 | 0.037* | ||
| TbSp | mm | 0.285±0.041 | 0.322±0.047 | 0.025* | ||
| TbN | 1/mm | 2.206±0.108 | 2.077±0.429 | 0.055 | ||
| Cortical bone parameter | CtTh | mm | 0.830±0.107 | 0.832±0.076 | 0.837 |
BV/TV = bone volume fraction (bone volume/total volume); TbTh = trabecular bone thickness; TbSp = trabecular bone separation; TbN = trabecular bone number; CtTh = cortical bone thickness.
