Palmar dermatoglyphics in oral leukoplakia and oral squamous cell carcinoma patients

Abstract

Background and Objective: Dermatoglyphics are the dermal ridge configuration on the digits, palms and soles. They are genetically determined and influenced by environmental forces that are operating before birth. Several studies have shown association between dermatoglyphics and different types of cancer. Hence this study was undertaken to determine whether specific dermatoglyphic patterns exists which help in predicting the occurrence of oral squamous cell carcinoma (OSCC) and oral leukoplakia. Materials and Methods: Finger and palm prints were collected using Ink method from 30 subjects with OSCC, 30 subjects with oral leukoplakia and 30 healthy controls and were evaluated qualitatively and quantitatively. Results: Arches and loops were more frequent in cases than in controls whereas whorls were more frequent in control group ( P < 0.01). Conclusion: Our study concluded that dermatoglyphic patterns may have a role in identifying individuals either with or at risk for developing oral leukoplakia and OSCC. Hence can be used to identify high risk group, so that early primary and secondary preventive measures can be instituted in order to prevent the occurrence of these lesions.
