Unraveling the Enigma of Dental Caries through Conventional Analysis using Finger Print Forensics among the Students of Nadiad City, Gujarat

Introduction: There is growing interest in identifying genetic predispositions to dental caries using non-invasive tools. Dermatoglyphics, examining dermal ridge patterns on the hands and feet, is linked to genetic foundations. Galton’s theory asserts fingerprint constancy. In dentistry, dermatoglyphics gains attention for its correlation with students pathologies. This study evaluates the association of dental caries in students with dermatoglyphics. Materials and Methods: The research at the Department of Oral and Maxillofacial Pathology, Dharmsinh Desai University, involved 50 subjects (28 females and 22 males) with normal fingerprints. Ethical clearance was obtained from the institute’s Ethics Committee. Fingerprints were recorded using the conventional method, employing ink, paper, roller, glass slab and sponging pad. The prints were examined, classified and analysed through the Cummins method, categorising them into whorls, loops and arches. The dental caries were assessed through the decayed, missing and filled teeth (DMFT) scores of the participants. The DMFT score was tested for association and difference according to the type of fingerprint pattern. Results: Females commonly exhibit loop patterns, while males show an equal distribution between loops and whorls. The connection between fingerprint patterns and DMFT scores is notable. A Chi-square test for left-side patterns (Chi-square = 27.74, P = 0.002) reveals a strong association, linking specific patterns to distinct DMFT scores. Similarly, for right-side patterns (Chi-square = 11.349, P = 0.045), there is significance, emphasising the relationship between fingerprint types and dental caries. Conclusion: The study examined the connection between fingerprint patterns and dental caries in children, discovering a positive correlation. Specific patterns such as arch, loop and whorl were linked to caries presence or absence, suggesting their potential as an early detection tool, although accuracy might vary based on genetic factors.
