Background:
The purpose of this study is to illuminate the role of CBCT in forensic dentistry through variations of mandibular measurements of Bonwill's triangles in gender determination among the Iraqi population.
Materials And Methods:
In this retrospective study 70 CBCT scans were analyzed to measure the Bonwill's triangle, 35 for males and 35 for females aged between 20 and 50 years, all data were collected at the oral and maxillofacial radiology department in Ghazi AL-Hariri hospital for 3 months, and the data were obtained using a Kavo CBCT device (3D On Demand software; field of view: 8 × 16 cm; 90 kV; 10 mA; voxel size: 0.38 mm), The software is equipped with a ruler to take measurements for this study.
Results:
In this study, 70 CBCT scans were analyzed (35 females and 35 males). All the measurements in males were found larger than in females, the R-LC in males was 102.4 mm whereas in females it was 96.7 mm. TheI-RC was 101 mm in males and 94.9 mm in females, whereas the I-LC in males was 99.5 mm and 95 mm in females. The semi-perimeter was 100.96 mm in males and 95.53 mm in females.
Conclusions:
This study found that although Bonwill's triangle differs significantly in size between males and females, its shape remains equilateral in both sexes, indicating no sex-based variation in the geometric form of the triangle.
