Abstract

Next to pelvis, the skull is the most easily sexable portion of the skeleton. As a component of the skull, mandible shares its own characteristics, but its indices for sex determination are neither as abundant  as those of the skull. Mandible is the strongest and largest bone of the skull. It shows various morphological features which may shows changes with references to age, sex and race. The present study was undertaken to obtain the information on variation  of lingua and coronoid process, distribution of genial tubercles and presence or absence of median pit. The material for this study comprised of a collection of 84 (168 sides) dry adult human mandibles obtained from Bone bank available in the department of Anatomy, Goverenment medical college, Aurangabad.

Triangular shaped lingulae were found in 80 (47.67%) sides, truncated in 18 (10.71%) sides, nodular in 47 (27.97%) and assimilated in 23(13.69%) sides.   Triangular lingulae were found bilaterally in 32, truncated in 4, nodular in 19 and assimilated in 8 mandibles.  Triangular coronoid process was found more in male bones (62 sides). Pattern of Type II genial tubercle (41 mandibles) was found to be most prevalent.

In Summary types of lingula and coronoid process can be used for sexing of mandible.
