Sexual Predilection of Lingual Morphology - A Cross-sectional Comparative Study

Proof of identity acts as a key title role in any criminal investigation. Training of tongue prints has been documented and acknowledged as the gold standard for personal identification worldwide nowadays. Tongue printing has proved as an innovative biometric tool and can be relied upon as an authoritative forensic tool. Research works have been carried out on tongue print independently. However, studies focusing on the morphology or shape of the tongue have not been commenced to a prodigious scope.

The contemporary trial was undertaken upon the people to train and scrutiny the morphological shape of the tongue and validate their magnitude as assistance in sexual dimorphism.

Hundred dental students in the age group of 18-25 years were included in the trial. For the trial clinical scrutiny, photographs and lingual impressions were recorded of the tongue.

In the current trial of the shape of the tongue for gender identification, we used two classifications. According to TCM criteria, five tongue shapes were used for gender identification: rectangle, acute triangle, obtuse triangle, square, and circle. Among the 100 subjects, the square-shaped tongue was chiefly observed, trailed by the circle and obtuse triangle. In the second criteria, Stefanescu et al. classified tongues into two shapes: U- and V-shaped. When the tongue shape was scrutinized, U shape was seen in 79 persons and V shape in 21 persons out of 100 subjects.

Hence, the trial concluded that tongue prints exhibited a qualitative result among diverse sex groupings. It can be preached that the human tongue possibilities to distribute a point of exceptionality in morphological shape; besides, it is apt for utilization in gender acknowledgment.
