ABSTRACT:

Background: Methods based on measurements and morphometry are accurate and can be used in determination of sex. Even the bony remains like mandibular ramus can be used to predict the sex of the individual which will be of help for forensic experts. Morphometry of mandibular ramus will also be of importance for anthropologists, anatomists and prosthetists.

Materials and Methods: Coronoid height, maximum ramus breadth, minimum ramus breadth and maximum ramus height was measured in 200 adult cadavers.

Results: The coronoid height varied from 42.02 mm to 68.46 mm in males and it varied from 40.08 mm to 66.76 mm in females. The maximum ramus breadth in male mandible varied from 28.84 mm to 42.28 mm and in females it varied from 27.44 mm to 41.42 mm. The minimum ramus breadth in males varied from 21.92 mm to 36.80 mm, in females it varied from 17 mm to 34.26 mm. The maximum ramus height in males varied from 47.76 mm to 68.64 mm and in females it varied from 42.56 mm to 69.56 mm.

Conclusion: All the parameters measured were higher in males than females. Comparison studies revealed that the South Indian parameters were lesser than Thais, Croatians and Africans.

KEYWORDS: Mandibular ramus, Coronoid height, Ramus height, Ramus breadth.
