Agreement between Panoramic Radiography and CBCT for the Detection of Low Bone Mineral Density: A Cross-sectional Study.

Abstract

Objectives:To compare cone beam computed tomography (CBCT) and panoramic radiography in the detection of low bone mineral density patients.Methods:This study was done on 46 patients obtained from the Department of Oral and Maxillofacial Radiology, Faculty of Dentistry, Ain Shams University. Patients were screened by DEXA, panoramic radiography, and CBCT scans. Radiographic quantitative and qualitative assessment for both right and left sides was performed. Radiographic analysis was compared with DEXA scan results.Results:The panoramic mental and mandibular indices and the cone beam mandibular and inferior indices (MI, PMI, CTMI and CTI) were in good agreement with each other. While the panoramic and cone beam cortical indices (MCI and CTCI) were different to each other, in the detection of low bone mineral density patients.Conclusions:For the radiographic detection of low bone mineral density, there is a good agreement between panoramic radiography and cone beam computed tomography regarding the mental and mandibular indices.
