Summary
Mandibular canine dimensions show significant sexual dimorphism, with males exhibiting larger measurements. This research supports using these canine traits as a valuable tool for gender estimation in forensic identification.
Area of Science:
- Forensic Anthropology
- Odontology
- Human Identification
Background:
- Human identity is fundamental, and its recognition, even post-mortem, is crucial for compassionate societies.
- Establishing identity after death often relies on skeletal and dental evidence.
Purpose of the Study:
- To measure mandibular canine dimensions.
- To evaluate the utility of mandibular canine measurements for gender estimation.
Main Methods:
- The study included 200 individuals (100 males, 100 females, aged 18-25).
- Measurements included mesiodistal canine width and intercanine distance (intraoral and on casts).
- The mandibular canine index (MCI) was calculated, and data analyzed using t-test/Mann-Whitney and discriminant function analysis.
Main Results:
- Significant sexual dimorphism was observed, with all measured mandibular canine parameters (intercanine distance, canine width, MCI) being larger in males.
- Discriminant function analysis achieved 73% accuracy in sex classification based on these parameters.
Conclusions:
- The study confirms significant sexual dimorphism in mandibular canine dimensions.
- Mandibular canine measurements are recommended as an applicable additional method for gender determination in human identification contexts.
