title: Determination of sexual dimorphism via maxillary first molar teeth in Himachali population.
abstract: BACKGROUND
  Sex determination of skeletal remains forms part of archaeological and medicolegal examinations. It is an aspect of forensic odontology. Forensic odontology primarily deals with identification, based on recognition of unique features present in an individual's dental structures. Correct sex determination limits the pool of missing persons to just one half of the population.
  
  
  OBJECTIVE
  Purpose of this study is to evaluate the existence of sexual dimorphism and variation in left and right maxillary first molars using bucco-lingual and mesio-distal dimensions in population of Sirmour District, H.P.
  
  
  METHODS
  Base sample comprised 100 subjects (50 males and 50 females) of an age group ranging from 17 to 25 years.
  
  
  METHODS
  Unpaired t-test.
  
  
  RESULTS
  It was observed that the comparison of mean values of bucco-lingual and mesio-distal parameters showed highly statistically significant differences between males and females, measured both intraorally and on study casts. There were no significant differences between the mean values of both the parameters on the left side as compared to right side.
  
  
  CONCLUSIONS
  The study concludes that sexual dimorphism is population specific. Among Himachali people, mesio-distal dimensions and bucco-lingual dimensions of first molar can aid in sex determination.
