Determining the relationship between Dermatoglyphics with Malocclusion: A pilot study among the population of Gujarat

Abstract

Introduction: Background: Dermatoglyphics, defined by Cummins and Midlo (1926), refers to
the study of naturally occurring dermal patterns on hands and feet. Dermatoglyphics develops
during the 12th week of the intrauterine period, with the development of dental
tissues. According to certain theories, dermatoglyphics is believed to be genetically controlled,
whereas malocclusion is genetically and environmentally controlled in the most common dental
diseases.48 patients ranging in the age of 18-35 years from Gujarat. Malocclusion was
classified according to Angles’: class 1, class2 and class3. Dermal patterns of digits were
broadly classified into: loop, arch and whorl. Data collected was statistically analyzed by
Independent t-test and ANOVA tests.
Result: The result of the study was that the Loop ridge pattern was seen in the majority of class
1 and 2 malocclusions, whereas whorl ridge pattern was seen in the majority of class 2
malocclusions especially in the left and ring fingers. There was relevant significance (p>0.05)
seen at the right middle finger with the malocclusion.
Conclusion: This study suggests that dermatoglyphics might aid as a cost-effective screening
tool. At an early age, it might be used as an indicator of malocclusion, aiding the treatment
planning to establish a pleasing occlusion. In Forensics, victim identification and comparison
can be done for fragmented, decomposed or burnt bodies.
