Shokri A, et al. - Researchers assessed the relationship between bone mineral density (BMD) determined by cone-beam computed tomography (CBCT) gray values and BMD determined by dual-energy X-ray absorptiometry (DEXA). The investigators selected women over 50 years of age, requiring CBCT scans for implant treatment. It was observed that out of 61 asymptomatic patients, 47.5% had abnormal BMD based on the T-score of the femoral neck and 55.7% had abnormal BMD based on the T-score of the lumbar spine. They observed that a strong relationship exists between the result of DEXA and CBCT gray values at different sites in the maxilla. With an accuracy of 66% to 67%, a gray value <298 at the maxillary tuberosity can differentiate between osteoporotic and normal people suggesting the need for DEXA analysis.
