| Abstract | | Loth and Henneberg studied the flexure of the mandible in a subjective grading system later
modified by actual measurements by Lin. This study aimed to assess the effectiveness of mandibular flexure angles in
sex estimation in panoramic radiographs of the South Indian population.
Material and methods: The study involved the collection of 170 digital panoramic radiographs from males and 170
from females aged fifteen to twenty-five years. The canonical variate scores, centroids, and discriminant function
equations were analyzed.
Results: The analysis revealed significant differences in the left and right antegonion angles between males and
females (p=0.001 for both). Females exhibited higher mean angles for both left (170.88°) and right (171.48°), respectively,
compared to males (166.95° and 168.01°, respectively).
Conclusion: The analysis also revealed that the mandible flexures can be used efficiently to test muscle activity, in
forensic and anthropological settings. | | | | Keywords | | Mandible – Sexual dimorphism – Panoramic radiograph – Mandibular flexure angle – Justice | | |
