title: Applicability of Berry's index in bite mark analysis.
abstract: OBJECTIVE
  This study attempts to highlight the usefulness of applying Berry's Index as an adjuvant to support and aid in bite analysis.
  
  
  METHODS
  This study was conducted among 100 students between the ages of 18-30 from Mar Baselios Dental Collage, Kothamangalam. Out of the 100 subjects, there were 50 males and 50 females. The data obtained was tabulated and analyzed using Statistical Package for Social Sciences, Version 16 (SPSS).
  
  
  RESULTS
  The mean value of the width of the upper central incisor for male and female was 0.7602 cm and 0.7765 cm respectively. The mean value of the bizygomatic width for male and female was 12.54 cm and 12.42 cm respectively. The correlation between the upper central incisor width and the bizygomatic width was inferred to have a good positive correlation with a value 0f 0.613. Pearson correlation coefficient with greater correlation between the upper central incisor width and the bizygomatic width in female patient (r = 0.678) compared with male patient (r = 0. 525).
  
  
  CONCLUSIONS
  Berry's Index can be a useful adjuvant to bite analysis by providing a means of determining the facial proportions of an individual from the width of the central incisors.
