Comparison of Trabecular Bone Mineral Density Measurement Using Hounsfield Unit and Trabecular Microstructure in Orthodontic Patients Using Cone-Beam Computed Tomography

The aim of this study was to measure the bone mineral density specific regions maxilla, mandible, and first cervical vertebra using Hounsfield unit trabecular microstructure pattern analysis compare two methods. In study, cone-beam computed tomography (CBCT) images were obtained from 58 patients. Trabecular thickness, number, separation, volume fraction measured in 484 for parameters grayscale value. There no difference between right left side every site males females. thickness number high order anterior base mandibular body, vertebra, condyle. Bone condyle, (p < 0.05). positively correlated unit, separation negatively 0.005). This suggests that it is possible various sites analysis.
