| Popis: | Objective: The purpose of the present study is to determine the gender of individual using mandibular ramus parameters, namely, gonial flexure and minimum ramal breadth in panoramic radiographs. Materials and Methods: A cross-sectional study has been conducted using 100 panoramic radiographs from the archives of the Department of Oral Medicine and Radiology, Yenepoya Dental College, Mangalore. Two parameters, namely, gonial flexure and minimum ramal breadth were measured using Agfa Nx software for each digital radiograph. The mean values were calculated and compared between females and males using unpaired t-test and discriminant functional analysis. Results: It was observed that gonial flexure is more obtuse in females when compared to males (R gonial angle, t = 2.965, P = 0.004 L gonial angle t = 2.458, P = 0.016) and the minimum ramal breadth was wider in males compared to females (R ramus breadth, t = −2.846, P = 0.005, L ramus breadth, t = −2.478, P = 0.015) and also the discriminant function analysis was also found to be significant at P = 0.011, Wilks' lambda = 0.875 (Goodness of fit). Conclusion: Mandibular ramus parameters, namely, gonial flexure and minimum ramal breadth can be used efficiently to determine gender which has implication in forensic medicine. |
