“…31 With regard to the correlation between FD and lumbar spine BMD measured by DXA (t-score), it was observed that there was a negative significant correlation between FD and BMD of the lumbar spine. In support to our results, Hua et al 32 evaluated decalcified bone samples in relation to DXA using CBCT and found a negative correlation between FD and bone density.…”

Objectives: The aim of the present study was to assess the feasibility of using mandibular CBCT radiomorphometric indices and box-counting fractal dimension (FD) to detect osteoporosis in post-menopausal females, compare them with the healthy control group and to correlate the findings with the bone mineral density measured by dual X-ray absorptiometry (DXA). Methods: This study consisted of 50 post-menopausal females, with age ranging from 55 to 70 years. Based on their DXA results, they were classified into osteoporotic and control groups. Mandibular CBCT radiomorphomertic indices and FD analysis were measured. Results: Significant differences were found for the CT cortical index scores (CTCI), CT mental index (CTMI) and CT mandibular index (CTI) between the control and osteoporotic groups. The control group showed higher mean values than the osteoporotic group. For FD values, no significant differences were found between the two groups. Conclusions: CBCT radiomorphometric indices could be used as an adjuvant tool to refer patients at risk of osteoporosis for further assessment.

“…Nonetheless, the superior radiographic imaging properties of CBCT have led to an increase in application of the technology among dental practitioners (27). Furthermore, research on the evaluation of jaw bones using CBCT CT value measurements (6,10,9,28), radiomorphometric indices (15) and computer software is ongoing (29)(30)(31)(32).…”

“…Fractal dimension, and its relation with bone architecture, has been investigated on in vitro, animal and clinical CBCT images. [23][24][25][26] Various other studies have measured morphometric and other parameters, correlating values from CBCT with those from mCT and dual-energy X-ray absorptiometry. [27][28][29][30][31] Correlation coefficients were typically interpreted as "high".…”

Objectives: To compare microarchitecture parameters of bone samples scanned using micro-CT (mCT) to those obtained by using CBCT. Methods: A bone biopsy trephine bur (3 3 10 mm) was used to remove 20 cylindrical bone samples from 20 dry hemimandibles. Samples were scanned using mCT (mCT 35; SCANCO Medical, Brüttisellen, Switzerland) with a voxel size of 20 mm and CBCT (3D Accuitomo 170; J. Morita, Kyoto, Japan) with a voxel size of 80 mm. All corresponding sample scans were aligned and cropped. Image analysis was carried out using BoneJ, including the following parameters: skeleton analysis, bone surface per total volume (BS/TV), bone volume per total volume (BV/TV), connectivity density, anisotropy, trabecular thickness and spacing, structure model index, plateness and fractal dimension. Pearson and Spearman correlation coefficients (R) were calculated. CBCT values were then calibrated using the slope of the linear fit with the mCT values. The mean error after calibration was calculated and normalized to the standard deviation of the mCT values. Results: R-values ranged between 0.05 (plateness) and 0.83 (BS/TV). Correlation was significant for both Spearman and Pearson's R for 8 out of 16 parameters. After calibration, the smallest normalized error was found for BV/TV (0.48). For other parameters, the error range was 0.58-2.10. Conclusions: Despite the overall correlation, this study demonstrates the uncertainty associated with using bone microarchitecture parameters on CBCT images. Although clinically relevant parameter ranges are not available, the errors found in this study may be too high for some parameters to be considered for clinical application.

Bone quality assessment based on cone beam computed tomography imaging

Abstract: The results of this study suggest that fractal analysis and bone area measurement have potential to evaluate bone quality on CBCT images, while density measurement does not seem to be valid.
