Introduction. Gonial angle and antegonial region are important landmarks in mandible which is influenced by gender, age, and dental status. The objective of this study was to evaluate the gonial angle, antegonial angle, and antegonial depth and to investigate their relationship to gender, age group, and dental status. Materials and Methods. A total of 1060 panoramic radiographs were evaluated: the dentulous group, 854 subjects and the edentulous group, 206 subjects. The patients were grouped into six age groups of 10-years each. Gonial angle, antegonial angle, and antegonial depth were measured from panoramic radiographs. Results and Discussion. Corelation of age with gonial angle, antegonial angle and antegonial depth was not significant. Significant difference in mandibular angle was found between males and females. Males had significantly smaller antegonial angle and greater antegonial depth than females. Significant difference was found for gonial angle, antegonial angle, and antegonial depth between right and left sides of mandible. Conclusion. Gonial angle, antegonial angle, and antegonial depth can be implicated as a forensic tool for gender determination but not suitable for age determination.
引言。下颌角和下颌角前区是下颌骨的重要标志，受性别、年龄和牙齿状况的影响。本研究的目的是评估下颌角、下颌角前角和下颌角前深度，并研究它们与性别、年龄组和牙齿状况的关系。材料与方法。共评估了1060张全景X线片：有牙组854例受试者，无牙组206例受试者。患者被分为6个年龄组，每组10岁。从全景X线片上测量下颌角、下颌角前角和下颌角前深度。结果与讨论。年龄与下颌角、下颌角前角和下颌角前深度的相关性不显著。男女下颌角存在显著差异。男性的下颌角前角明显小于女性，下颌角前深度大于女性。下颌骨左右两侧的下颌角、下颌角前角和下颌角前深度存在显著差异。结论。下颌角、下颌角前角和下颌角前深度可作为性别鉴定的法医工具，但不适用于年龄鉴定。
