Abstract
ABSTRACTBackground: Dermatoglyphics refers to study of the intricate dermal ridge configurations on the skin covering the palmar and plantar surfaces of hand and feet. The basis of considering dermatoglyphic patterns as genetic marker for dental caries is that the epithelium of finger buds as well as enamel has ectodermal origin, and both develop at the same time of intrauterine life.Aim: To assess the relationship between fingerprint patterns and dental caries among preschool children of Lucknow city.Study design: This study was of cross-sectional design.Materials and methods: The study group comprised 512 preschool children 2-6 years of age. The prevalence of caries was recorded using "Dentition status and treatment needs" (WHO basic oral health assessment form, 1997). They were divided into three groups as follows: Group I (dmft score = 0-2), group II (dmft score = 3-4) and group III (dmft score ≥5). The handprints of each child were taken using a stamp pad. The fingertip patterns were analyzed according to the classical method and were classified according to the topological method. The frequency of occurrence of type of dermatoglyphic pattern on fingertip of each digit was noted.Statistics: Chi-square test was used to test the significant difference in proportions. Means were compared using Student’s t-test and analysis of variance (ANOVA) or F-test.Results: Subjects belonging to groups II and III showed maximum occurrence of whorl pattern on all digits. Group I subjects had maximum occurrence of arch pattern. All the variables had statistically significant value, with a degree of divergence of specific dermatoglyphic patterns among all three groups.Conclusion: The dental caries susceptibility of an individual increased with incidence of whorl pattern and it decreased with incidence of arch pattern.How to cite this article: Singh E, Saha S, Jagannath GV, Singh S, Saha S, Garg N.

Summary
Dermatoglyphics as coined by Cummins et al[1] refers to study of the intricate dermal ridge configurations on the skin covering the palmar and plantar surfaces of hand and feet. Dermatoglyphics is the art and science of studying the patterns of fingerprints.[2] Fingerprints are found in humans and some animals. They are unique to all individuals and remain unchanged over the lifetime.
