Orbital aperture morphometry in Indian population: A digital radiographic study.

Area of Science:

• Forensic anthropology
• Anthropometry

Background:

• Orbital aperture morphology can aid in determining individual identity.
• Sexual and ethnic variations in orbital measurements are valuable in forensic science.

Purpose of the Study:

• To assess orbital aperture dimensions in Indian individuals.
• To establish the relationship between orbital measurements and gender in this population.

Main Methods:

• Retrospective analysis of digital radiographs from 101 Indian individuals (50 males, 51 females).
• Measurement of orbital width, height, and inter-orbital distance using specialized software.
• Statistical analysis including t-tests and discriminant function analysis.

Main Results:

• Significant differences in orbital width and inter-orbital distance were observed between genders.
• Discriminant function analysis achieved an 86.1% accuracy rate for gender determination.

Conclusions:

• Orbital aperture measurements provide a reliable method for gender determination in human identification.
• A discriminant score threshold of 1.0365 can differentiate between male and female skulls.
