Abstract :

Introduction: Every tongue varies from the other in shape and texture with its uniqueness comparable to that of fingerprint. Tongue being a highly muscular organ can be easily drawn for the purpose of inspection and owing to its unique nature it is difficult to replicate. Morphological and biological characteristics of the tongue collectively forms the tongue print. Biometric authentication inculcates tongue print combined with its visual imprint so as to obtain a secure method of identification. The present study aims at assessing the inherit characteristics of the tongue alongside its visual imprints thereby proving the tongue to be a valuable aid in biometric authentication. Aims & Objectives: To compare the differences in location of fissures, depth of fissures, shape of tongue and distribution of papillae between Malaysian and Indian population. Materials and Method: 20 subjects (10 Malaysians and 10 Indians) in the age group of 20–25 years were included in this study. Following oral examination, digital visual imprints and alginate impression of dorsum of the tongue were made, subsequently positive replica of impression was obtained with dental stone. The visual imprint along with the obtained cast were studied and analysed on the basis of inherit morphological features such as shape, fissures and papilla characteristics. Results: The predominant shape and characteristic on dorsum of tongue was U and presence of vertical fissures in both the populations respectively. Differentiating feature between Indian and Malaysian population was increased number of papillae in the posterior region of the tongue in Indian subjects.
