Introduction: As a public health problem, efforts against osteoporosis should be made by all the health sectors including dentists.

Early diagnosis of this disease improves prognosis and quality of life for patients.

Dentists are commonly visited by a large segment of the population, then why don’t their equipment and techniques are being utilized to diagnose such a silent disease? Aim: To evaluate some Cone-Beam-CT (CBCT) derived values in the diagnosis of osteoporosis in menopausal and postmenopausal women using simple non-professional programs.

Materials and Methods: 45 women who went under DXA examination for hip and lumbar vertebrae were imaged by CBCT (field of view 13x15 cm and a 0.25mm voxel size).

Slices from the mandibles were selected and some quantitative analyses were performed.

Analyses of 2 filters of 3D images were also done.

Pearson correlation and logistic regression analyses were performed to evaluate the relationship between T-scores (for the hip and lumbar) and CBCT-measurements.

Results: Pearson correlation was significant only for variables derived from mandibular slices (r ranged from 0.345-0.548; 0.000

Equations of predicting osteoporosis and T-score were formulated depending on simple logistic regression analysis (the accuracy ranged from 61.4-81.8%).

Conclusions: Predicting osteoporosis from radiographic density of the mandibular slices was presented with a good accuracy.
