Dermatoglyphic Patterns and Skeletal Malocclusion: Dermatoglyphics is the study of the intricate dermal patterns found on the skin of the palmar and plantar surfaces of the hands and feet. The term dermatoglyphics means “skin carving.” He has proven to be of predictive value for both genetic and nongenetic diseases in the medical field. It has been noted that the period of embryonic development for oral and dermal tissues overlaps. Thus, any impact on the development of oral tissues during this period may also represent itself in the dermatoglyphic patterns. Aim: Keeping this in mind, the present study was designed to investigate the correlation between malocclusions and representation in dermatoglyphic patterns. Materials and Methodology: A total of 90 subjects were selected for the study. Thirty cases each of Class I, Class II, and Class III skeletal malocclusions were selected from the age group of 13–18 years of age with permanent molars present. Lateral cephalograms were taken and their dermatoglyphic patterns were recorded by rolling impression technique. The dermatoglyphic data were assessed for different finger ridge patterns and total ridge count (TRC). Results: On comparison of dermatoglyphic patterns between skeletal Class I, II, and III, the skeletal Class I group showed a markedly decreased number of loops and increased TRC. In the skeletal Class II group, we found markedly increased number of loops and markedly decreased TRC. In the skeletal Class III group, we observed a markedly decreased number of arches and increased TRC. Loops were found to be the most predominant pattern in the skeletal Class II and III groups. The mean TRC was found to be increased in the skeletal Class III group, followed by the Class I group and markedly decreased in the skeletal Class II group, which was statistically significant. Conclusion: It is concluded that dermatoglyphics can be used as a screening tool and for the early prediction of skeletal malocclusion at a younger age group. Dermatoglyphics have important practical and clinical implications which can be applied for preventive and interceptive orthodontics among pediatric patients and also for parent counseling.
