title: Sex determination of human mandible using metrical parameters.
abstract: BACKGROUND
  Determination of sex from an unknown human bone is an important role in forensic and anthropology field. The mandible is the largest and hardest facial bone, that commonly resist post mortem damage and forms an important source of information about sexual dimorphism.
  
  
  OBJECTIVE
  To determine the sex of unknown human adult mandible using metrical parameters.
  
  
  METHODS
  A random collection of 250 dry, complete, undamaged human adult mandibles of South Indian population were subjected to metrical parameters like Bigonial breadth, Bicondylar breadth and Mandibular length using Mandibulometer and Vernier caliper.
  
  
  METHODS
  The data's were expressed as Mean ± SD and then analyzed by t-test by using SPSS software. Discriminating point and limiting points were also calculated.
  
  
  RESULTS
  The mandibular length, bigonial breadth and bicondylar breadth showed significant statistical gender difference.
  
  
  CONCLUSIONS
  The present study revealed that the sex of human mandible can be assessed by using metrical parameters as an additional tool to establish the identity of a person.
