Summary
This study analyzed lip print patterns in 400 Marathi individuals, finding significant sex differences. Digital photography revealed distinct predominant patterns between males and females, aiding forensic science.
Area of Science:
- Forensic Science
- Anthropology
- Genetics
Background:
- Lip prints offer valuable forensic investigation data.
- Understanding lip print pattern distribution is crucial for identification.
- Previous research indicates potential variations across populations.
Purpose of the Study:
- To determine lip print pattern distribution in a Central Indian (Marathi) population.
- To identify predominant lip print patterns.
- To evaluate sex-based differences in lip print patterns.
Main Methods:
- Digital photography was used for convenient data collection.
- Analysis focused on the central 1 cm² of upper and lower lips.
- Suzuki and Tsuchihashi's classification system was applied.
Main Results:
- Overall, Type IV (27.5%) was the most prevalent pattern, Type III (6.25%) the least.
- Type II was predominant in males (32%), while Type IV was most common in females (32.5%).
- Statistically significant differences (p < .01) were found between sexes.
Conclusions:
- Lip print patterns exhibit significant sex-based variations in the Marathi population.
- These findings contribute to forensic odontology and individual identification.
- Digital analysis offers a practical method for lip print pattern assessment.
