EVALUATION OF DERMATOGLYPHIC PATTERNS AND THEIR CORRELATION WITH SKELETAL MALOCCLUSIONS

Abstract

Background and Objectives: Dermatoglyphics deals with the study of the epidermal ridges and their congurations on the ngers, palms and soles. Epidermal ridge patterns form early in fetal development and remain unchanged throughout life and play a signicant role in the diagnosis of many disorders with genetic background. As the primary palate, lip and dermal ridges develop during the same period of intrauterine life, the genetic message contained in the genome - normal or abnormal, is deciphered during this period and is also reected by dermatoglyphics. The present study was undertaken to evaluate the different dermatoglyphic patterns and their correlation with skeletal malocclusions. The study was conducted on 90 individuals divided into 3 equal groups- skeletal Methods: class I, II and III. Dermatoglyphic patterns were recorded using ink method following rolling impression technique. The dermatoglyphic data was assessed for different nger ridge patterns and total ridge count (TRC). On compar Results: ison skeletal class I group showed markedly decreased number of loops and increased total ridge count (TRC). Skeletal class II showed markedly increased number of loops and markedly decreased TRC. Skeletal class III showed markedly decreased number of arches and increased TRC. Loops were found to be the most predominant pattern in skeletal class II and III groups. The mean TRC was found to be increased in skeletal class III group and markedly decreased in skeletal class II group which was statistically signicant. Dermatoglyphics can be used as a screening tool and for early prediction of skeletal mal Conclusion: occlusion at a younger age group. Dermatoglyphics have important practical and clinical implications which can be applied for preventive and interceptive orthodontics among paediatric patients and also for parent counseling.
