Dermatoglyphic Pattern Assessment in Smokeless Tobacco Users in the North Gujarat Population: A Comparative...

Area of Science:

• Forensic Anthropology
• Human Genetics
• Dermatoglyphics

Background:

• Dermatoglyphic patterns are unique and genetically determined, remaining constant throughout life.
• Previous research suggests a genetic association between smokeless tobacco use and specific dermatoglyphic traits.
• Understanding these patterns can aid in identifying predispositions and potential health risks.

Purpose of the Study:

• To investigate and compare dermatoglyphic patterns, including the ATD angle and fingerprint patterns, between smokeless tobacco users and non-consumers in the North Gujarat population.
• To explore the potential genetic link between smokeless tobacco consumption and observable dermatoglyphic variations.

Main Methods:

• A comparative study involving 500 subjects: 250 smokeless tobacco users and 250 non-consumers from North Gujarat.
• Quantitative analysis of the ATD angle using Student's t-test.
• Qualitative analysis of fingerprint patterns (loops, whorls, arches) using the Chi-square test.
• Statistical significance was determined using a P value of 0.05 or less.

Main Results:

• A statistically significant reduction in the ATD angle was observed in both male and female smokeless tobacco users compared to controls (P < 0.001).
• Smokeless tobacco users exhibited a significantly lower frequency of whorls and arches, and a higher frequency of loops in their fingerprints compared to non-users (P < 0.05).

Conclusions:

• This study establishes a significant association between smokeless tobacco use and specific palmar dermatoglyphic patterns in the North Gujarat population.
• While dermatoglyphics alone cannot diagnose substance abuse, these findings contribute to understanding the genetic underpinnings and may inform future diagnostic guidelines.
