RESUMO
Background: Dermatoglyphics play an important role in the identification of a person as well as identifying a person with a genetic abnormality. Hence, the present study was conducted with an aim to explore the association between the fingerprint patterns and oral potentially malignant disorders, oral squamous cell carcinoma (OSCC), individuals with habit and without lesion and the control group. Materials and Methods: A cross-sectional study comprising of 100 individuals divided into 5 groups with 20 individuals in each group based on their habit and the presence of oral lesions. Group 1 included individuals with oral leukoplakia (OL), Group 2 included individuals with oral submucous fibrosis (OSMF), Group 3 included individuals who had OSCC, Group 4 individuals had tobacco habits but without lesion and Group 5 comprised of control individuals. The fingerprints of all the study subjects were recorded using a standard ink method. They were analyzed qualitatively and quantitively. Results: The present study showed a predominance of that loop patterns in all the groups. The frequency of the whorled pattern was higher in subjects with OSMF as compared to OL and OSCC. The arch pattern was comparatively lesser in subjects with OL than OSMF subjects. The right-left comparison of the fingerprint patterns in all the five groups, except Group 4, showed a significant association and correlation. The Group 4 individuals were showing the least correlation between sides. Conclusion: The study concluded that dermatoglyphics can be used as a potential marker to identify the subjects with risk for potentially malignant oral disorders and oral cancers.
