Tongue is a vital organ which performs multiple actions such as articulation of speech, perception of taste, and formation of food bolus. The tongue is the only internal organ which can be easily drawn out and displayed for inspection and palpation purposes. By means of its shape and texture, its aspect and colour analysed in a particular moment, this organ is helpful due to its exposed portion comprising information with visible differences from one individual to another, and may be easily called and used as a “lingual impression”. The human tongue is encased within the oral cavity, where it lies isolated from and protected against the external environment, just as the palatine folds do, unlike the other notorious elements employed in human identification. Hence, we, in this original study are describing the varied tongue patterns emphasizing the uniqueness of tongue. Also we have included certain morphological features for assessment like tongue size, shape, colour, texture, margins and tip which has not been mentioned in the literature so far. Considering these criteria, we have formulated a simple working classification system of tongue patterns.
