Exploring the association between dermatoglyphic patterns and malocclusion types – A case–control study

Abstract

ABSTRACT Background and Objectives: Dermatoglyphics is the study of fingerprints and skin patterns. During the intrauterine period, the development of dermatoglyphic patterns and dental hard tissues occurs at the same time. Dermatoglyphics has proved to be a potential tool in predicting dental anomalies. Hence, with the help of dermatoglyphics, we can explore the association between various dermatoglyphic patterns and types of malocclusion. Methods: A case–control study consisting of 150 children aged 12–14 years was selected. Based on the type of occlusion, the participants were grouped into skeletal class I normal occlusion (controls), skeletal class II malocclusion, and skeletal class III malocclusion. The fingerprints were analyzed using the ink method. The molar relation was determined according to Angle’s classification of malocclusion. The relation of fingerprints was studied with the molar relation recorded using the study models. Dermatoglyphic parameters were examined in these subjects. Results: In the study, it was observed that there was a notable increase in the occurrence of whorl pattern among patients with skeletal class II malocclusion (55%) and skeletal class III malocclusion (55.8%). On the other hand, in the skeletal class I group (controls), the frequency of loop pattern (66.6%) was found to be significantly higher. It was also noted that there was a slight decrease in the frequency of whorl patterns in skeletal class II patients as compared to skeletal class III patients. Conclusion: The whorl fingerprint pattern found in the study may indicate a higher likelihood of skeletal class II and III malocclusion in the general population.
