Summary
Lip print patterns and measurements show significant ethnic variations among Lithuanian, Polish, and Russian women. These distinct lip print characteristics could aid in forensic identification and anthropological studies.
Area of Science:
- Forensic Science
- Anthropology
- Human Anatomy
Background:
- Lip prints are unique and can be used for identification.
- Understanding ethnic variations in lip prints is crucial for forensic applications.
- Previous research has explored lip print patterns, but ethnic variations require further investigation.
Purpose of the Study:
- To document and classify common lip print patterns and measurements.
- To evaluate variations in lip prints among Polish, Russian, and Lithuanian women.
- To analyze lip morphometry and its correlation with ethnicity.
Main Methods:
- Lip prints from 371 women (Lithuanian, Polish, Russian) were collected and classified into sextants.
- Lip morphometry was analyzed using 3D photography (Vectra M3 camera) on 120 participants.
- Statistical analysis was performed to determine significant differences between ethnic groups.
Main Results:
- Type I lip prints were most common in Lithuanians, Type III in Poles, and Type V in Russians.
- Statistically significant differences were observed in lip print patterns (Type I, Type III) and ethnicity.
- Significant variations were found in lip measurements including medial vertical height, upper lip height, philtrum width, and vermilion dimensions across ethnicities.
Conclusions:
- Lip print patterns and morphometric measurements exhibit significant ethnic variations among Lithuanian, Polish, and Russian women.
- These findings support the potential use of lip prints in forensic identification and anthropological studies.
- The observed morphometric variations align with previous research on Caucasian populations.

Adolescents from ethnic minority backgrounds face a multifaceted journey in forming their identities, shaped by the intersections of cultural expectations and personal exploration. For these adolescents, identity formation involves not only typical developmental challenges but also navigating the perceptions and attitudes of the majority culture. As they grow, adolescents in ethnic minority groups often become increasingly aware of stereotypes, social biases, and discrimination, all of which...
