Bone Quality Assessment Using Cone Beam Computed Tomography of the Mandible in Correlation to Dual Energy XRay Absorptimetry
Journal Title: IOSR Journal of Dental and Medical Sciences (IOSR-JDMS) - Year 2018, Vol 17, Issue 12
Abstract
Cone beam computed tomography (CBCT) of the mandible allows accurate assessment of the maxillofacial anatomic relationships in 3D and as we know any decrease in the body bone quality can affect jaw bones, therefore this study was performed to evaluate the efficacy of mandibular CBCT in assessing bone quality in postmenopausal women and to correlate it to the Dual energy x-ray( DEXA). Based on the DEXA results, twenty four patients were classified into osteoporotic (test) and non-osteoporotic (control) groups. CBCT examination was done as part of surgical treatment. The computed tomography mandibular index superior (CTIS), the computed tomography mandibular index inferior (CTII), the computed tomography mental index (CTMI), and the computed tomography average trabecular bone density (CTBD) were measured and correlated to T-Score measured by DEXA. There were significant differences between the control and test groups in all indices. There was significant positive correlation between CBCT indices, CTBD and T-score. CTIS, CTII, CTMI and CTBD on the CBCT images can be used for assessing bone quality and so can detect presence of osteoporosis in post menopausal women visiting the dental clinic.
