Exploring connections among fingerprints, lip prints, and ABO blood groups in periodontitis: A cross-sectional analysis.

Abstract

Background: Research into forensic genetic markers in the onset and advancement of periodontitis is an area of growing interest. This analysis aims to examine the connection between the fingerprint patterns, lip print patterns, and ABO blood group in periodontitis patients and healthy participants.

Materials and methods: A total of 300 people participated in this cross-sectional analytical study, evenly divided into two groups: Group I (healthy participants) and Group II (patients with chronic periodontitis). Each participant's lip print, fingerprint, and ABO blood type were noted. The interaction between various participant groups concerning blood groups, lip prints, and fingerprints was examined using the Chi-square test. To examine the relationship among these variables in patients with periodontitis and those who are healthy, Spearman's correlation (ρ) was employed.

Results: The findings demonstrated a statistically significant increased frequency of whorl fingerprint patterns, reticulate lip print patterns, and O-positive blood types in patients with chronic periodontitis. In contrast, healthy participants showed greater rates of ulnar loops, Type I lip prints, and A-positive blood type.

Conclusion: Genetically determined characteristics such as fingerprint patterns, lip print patterns, and ABO blood groups can be utilized to evaluate the risk of periodontitis in an individual.
