BACKGROUND
The purpose of study of biometry of mandible is to evaluate the sex of the individual by statistically significant various parameters of the mandible and also a few selected landmark points on the mandible.
MATERIALS AND METHODS
100 mandibles collected from Department of Anatomy at Mamatha Medical College and NRI Medical College were included in the present study. The following parameters were studied. 1. Ramus - a. Breadth, b. Height; 2. Interlingular distance; 3. Angle of mandible; 4. Bonwill’s triangle.
RESULTS
Rami's breadth in males and females 34.16 and 30.8 mm; rami's height in males and females 49.76 and 44.24; T-test value is 10.61; angles of mandible in males - 104°, in females - 125°; interlingular distance in males - 78.28 mm, in females - 65.5 mm; angle of gonion in males - 400 and in females - 410; Bonwill’s triangle - are equal in 40% females and 20% in males.
CONCLUSION
Biometry of mandible useful in medicolegal cases to differentiate the sex and age in maxillofacial surgery. A multimetric analysis by experienced person is most essential for accurate conclusions.
