To assess the ability of CBCT in evaluating osteoporotic bone changes in type 2 diabetes mellitus patients in comparison to bone mineral density using DEXA scan.
Purpose: This study assessed the ability of CBCT in evaluating osteoporotic bone changes in comparison to bone mineral density by using DEXA scan in type 2 diabetes mellitus patients. Materials and methods: Thirty diabetic patients and thirty healthy control subjects were included in this study. The CBCT images were obtained from the left mental foramen region using New Tom GIANO (CEFLA)-SC Dental CBCT system. The axial, sagittal and coronal sections had prepared. The T-value was taken as a gold standard to determined BMD (Bone Mineral Density) of the lumbar vertebrae by Dual Energy X-ray Absorptiometry (DEXA) using a DEXA scanner LUNAR DPX NT (GE, USA). The intra-observer agreement and relationship between the CBCT measurements and BMDs relationship had assessed. Results: The result of the study showed statistically significant difference in the mean values of CTIS, CTII, CTMI indices measured on CBCT in the diabetic group and control group. Mean t- scores in both diabetic males and females is lesser as compared to the mean T score in the control group. A positive correlation has observed between T-score and CTIS, CTII and CTMI indices. The intraobserver variability between CTIS, CTII, CTMI and CTCI reveal strong agreement among various radio morphometric indices. Conclusion: The various radiomorphometric indices such as computed tomography mandibular index superior, computed tomography mandibular index inferior, and Computed Tomography Cortical Index (CTCI) and Computed Tomography Mental Index (CTMI) on CBCT can be used as an ancillary tool for the early detection of osteoporotic bone changes in type 2 diabetic patients.Author(s): Deepti Awasthi*, S Upasana, P Nidhi, R Akshay, D Manu, A Seema
