Abstract
The current study was established to compare the usefulness of panoramic radiography versus CBCT measurements in assessment of bone quality in osteoporotic patients in relation to DEXA readings. It was aimed also to correlate serum level of osteocalcin in premenopausal and postmenopausal women to dental radiographic morphometric indices. Patients &Methods A total of forty – five patients were sub-grouped as follow: group 1 (study group) : 15 female osteoporotic postmenopausal patients are attending the heumatology and Rehabilitation department. Faculty of Medicine. Mansoura University. group 2 (control group): 30 female patients who were never diagnosed as osteoporotic patients and were coming to the outpatient clinic at the faculty of dentistry. Mansoura University. They were seeking various dental treatments that needed panoramic and cone-beam CT radiographical examination. Patients were subgrouped as follow: Subgroup 2A: 15 female patients who were in the premenopausal stage. Subgroup 2B:15 female patients who were in the postmenopausal stage. All patients had undergone Dual Energy X-ray bsorptiometry (DEXA) scan for bone mineral density (BMD) measurements. Dental adiographs in the form of Panoramic and Cone Beam CT images were made for patients who needed various dental treatments. Certain linear measurements were made on dental images and correlated with BMD measured by DEXA scan. Serum Osteocalcin (OC) was evaluated and correlated with BMD and panoramic and CBCT linear measurements. Results This study showed significant positive correlation between panoramic linear indices and BMD measured by DEXA. There was also significant correlation between CBCT indices (mainly computed tomography mandibular index superior (CTMIS)) and BMD measured by DEXA. There was no significant correlation between serum Osteocalcin level and any of the panoramic indices except with the gonial index in the study group and antegonial index in the control 2A group. There was no positive correlation between serum Osteocalcin level and any of the CBCT linear measurements in all groups. Conclusions Panoramic indices can be correlated with DEXA BMD measurements and so can be used to diagnose osteoporosis in premenopausal and postmenopausal females. CBCT linear measurements made on coronal cuts have weak to moderate correlation with DEXA BMD measurements. Osteocalcin serum level has weak correlation with panoramic and CBCT BMD linear measurements and DEXA readings and so could not be used for diagnosis of osteoporosis.
