Abstract

Objectives: This study aimed to evaluate mandibular cortical index and texture analysis parameters derived from CBCT in women of different age groups and to explore their correlation.

Methods: A retrospective observational study was conducted on CBCT scans of 66 women, divided into two groups: Group A (32–50 years, n = 33) and Group B (51–76 years, n = 33). Computed Tomography Mandibular Index (CTMI) were measured at the mental foramen region, and texture analysis was performed using the gray-level co-occurrence matrix (GLCM) to extract eleven parameters. Statistical analyses included Student’s t-test, Mann–Whitney U test, and Pearson/ Spearman correlation coefficients.

Results: The mean CTMI was 4.10 mm in Group A and 3.25 mm in Group B, indicating greater susceptibility to low BMD in group B. Group A exhibited higher AngScMom and InvDiffMom values, reflecting greater uniformity and homogeneity of trabecular structure. Group B showed higher Contrast, SumOfSqs, SumEntrp, Entropy, DifVarnc, and DifEntrp values, indicating increased variance, dispersion, and disorganization of gray-level intensities. Positive correlations were observed between CTMI and AngScMom and InvDiffMom, while negative correlations were found with Contrast, SumOfSqs, SumVarnc, SumEntrp, Entropy, DifVarnc, and DifEntrp. Patients with cortical bone thickness below 3 mm, indicative of osteoporosis, exhibited higher SumOfSqs and SumVarnc.

Conclusions: Computed Tomography Mandibular Index and texture analysis parameters are associated with bone mineral density and may serve as valuable, low-cost, and low-radiation screening tools.
