Keywords:Berry’s formula, bitemark analysis, incisal width, bizygomatic width
Background: This study was done to evaluate the importance of applying Berry’s index in bite mark
analysis.With that, it is able to highlight the usefulness of Berry’s index in aiding the analysis of bite mark
of an individual.
Methods: The study was conducted among 60 students between the ages of 18-30 from Saveetha Dental
College, Chennai. The data that was obtained was then tabulated and statistically analyzed.
Conclusion: The results of the study revealed that the widths of both maxillary central incisors and the
bizygomatic width were higher in males when compared to females. A positive correlation can be found in
males compared to females in regard to both of the widths obtained. Berry’s index is a useful tool of high
forensic value and can be used to help in the identification of an individual’s facial proportions based on the
calculated width of the central incisors. Thus, it can be of correlation to that of forensic facial reconstruction.
