Abstract
Early detection of osteoporosis is important to maximize bone mass retention, reduce the risk of fracture, and avoid subsequent pain of these patients because the silent nature of this disease increases the difficulty of its diagnosis. Therefore, all medical professionals should participate in identifying susceptible patients and refer them for further analysis.
This study aimed at the evaluation of diagnostic efficacy of CBCT of the mandible in detection of osteoporosis and its correlation to skeletal BMD assessed by DEXA scan.
The study was conducted clinically on 24 postmenopausal female patients, referred for CBCT examination as a part of implant planning procedure.The study sample underwent DEXA scan at lumbar spine and left femur and were classified into two groups according WHO classification based on DEXA san results; control non osteoporotic patients (T-score >-2.5) and osteoporotic patients (T-score < -2.5).
In regard to CBCT scans of the mandible, the following indices were assessed : Computed tomography mandibular index superior CTIS, computed tomography mandibular index inferior (CTII), computed tomography mental index (CTMI: inferior cortical width) and computed tomography cortical index (CTCI).
Study results showed a statistically significant difference between the two groups regarding CTIS,CTII, CTMI and CTCI.

Concerning correlation between BMD measured by DEXA (T-score) at lumbar spine and CBCT indices it was found significant strong positive correlation between CTMI and T-score while CTIS and CTII showed only moderate correlation with T-score. However, there was no statistical correlation between CBCT indices and BMD measured at left femur.
The current study concluded that CBCT radiomorphometric indices could be used as a useful tool to predict osteoporosis and refer patients for further densitometric analysis.
