Cone-beam computed tomography (CBCT) is widely used in the preoperative qualitative and quantitative assessment of dental implant sites, offering dimensional accuracy, spatial resolution, gray density, and contrast comparable to those of classical CT scan, yet with disputable ability to determine bone mass density.
A systematic review of the literature was performed using the PubMed and SCOPUS databases, with terms referring to low bone mass and cone-beam computed tomography (CBCT).
Sixteen studies were included in the review. The results show different perspectives, but the evidence favors the use of CBCT, combined with dual-energy X-ray absorptiometry bone density scan (DXA) evaluation, for the assessment of the osteoporosis status of the aging population and, more specifically, in postmenopausal women. Radiographic density (RD) values of the dens and the left part of the first cervical vertebra show the strongest correlation coefficients and the highest sensitivity, specificity, and accuracy for predicting osteoporosis (OP) in the lumbar vertebrae and the femoral neck.
Our review suggests the potential of CBCT as a screening tool for patients with low bone mass using different radiomorphometric indices. Linear measurements of the inferior mandibular cortex were lower in osteoporotic individuals, indicating the perspective of CBCT also as a diagnostic tool for this disease.
锥形束计算机断层扫描（CBCT）广泛应用于牙种植部位的术前定性和定量评估，其尺寸精度、空间分辨率、灰度密度和对比度与传统CT扫描相当，但在确定骨密度方面的能力存在争议。
使用PubMed和SCOPUS数据库对文献进行系统综述，检索词为低骨量和锥形束计算机断层扫描（CBCT）。
该综述纳入了16项研究。结果显示了不同的观点，但证据支持将CBCT与双能X线吸收法骨密度扫描（DXA）评估相结合，用于评估老年人群，尤其是绝经后女性的骨质疏松状态。齿状突和第一颈椎左侧部分的放射密度（RD）值显示出最强的相关系数，以及预测腰椎和股骨颈骨质疏松（OP）的最高敏感性、特异性和准确性。
我们的综述表明，CBCT有可能作为一种使用不同放射形态计量学指标筛查低骨量患者的工具。骨质疏松个体下颌骨下缘皮质的线性测量值较低，这表明CBCT也有望成为诊断该疾病的工具。
