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.
