The performance of radiomorphometric indices in sex differentiation compared to the W index
Year: 2025

Study design: Observational Study
Abstract: Purpose: The aim of this study is to evaluate the effectiveness of the W-Index (WI) in differentiating between males and females, in comparison with the main radiomorphometric indices: the Mental Index (MI), Panoramic Mandibular Index (PMI), and Gonial Index (GI), in a group of healthy young adults. Materials and methods: Panoramic radiographic images from a group of 335 healthy young adults were retrospectively analyzed. Measurements of WI, PMI, MI, and GI were obtained. Statistical analysis included group comparisons, correlation assessments among the indices, and accuracy testing. Results: Both the WI and PMI showed statistically significant differences between males and females (p less than 0.001), whereas the MI and GI did not. The WI and PMI demonstrated satisfactory accuracy in distinguishing between sexes. When combined, WI and PMI improved classification accuracy. Higher values of WI and PMI were associated with males, while lower values were observed in females. Conclusion: The combined use of WI and PMI represents a reliable and non-invasive approach for sex determination in clinical and forensic settings.
