Summary
Mandibular ramus measurements are a useful tool for sex determination. Key measurements like ramus breadth and condylar height showed significant differences between sexes.
Area of Science:
- Forensic Anthropology
- Craniomaxillofacial Radiology
Background:
- Accurate sex determination is crucial in forensic investigations.
- Skeletal morphology, particularly the mandible, offers potential indicators for sex estimation.
Purpose of the Study:
- To assess the utility of mandibular ramus measurements for sex determination.
- To evaluate the anteroposterior and superoinferior angle of the mandibular condyle.
Main Methods:
- Retrospective analysis of orthopantomographs from 120 individuals (60 males, 60 females, aged 18-45).
- Mandibular ramus measurements performed using Master View 3.0 software.
- Discriminant function analysis applied to assess sexual dimorphism.
Main Results:
- Significant differences (P < 0.05) observed in maximum ramus breadth, condylar height, and projective height of the ramus between sexes.
- These parameters demonstrate statistical significance in distinguishing between male and female mandibles.
Conclusions:
- Mandibular ramus measurements provide a reliable method for gender determination in forensic contexts.
- Specific ramus dimensions are valuable indicators of sex.
