Bite Marks Analysis - An Innovative Computer Assisted Approach for Gender Determination | Chapter 11 | Current Trends in Disease and Health Vol. 3
Background: Bite mark analysis is an imperative area of forensic
odontology and considered the commonest form of dental evidence presented in
the criminal court. The process of comparing bite marks with a suspect’s
dentition includes analysis and measurement of shape, size and position of an
individual’s teeth. The present study was aimed to evaluate
the bite marks of males and females using a novel indirect computer assisted
method and explicate its application in forensic odontology.
Materials
and Methods: 60 subjects (30 males and 30 females) with normal occlusion were
included in the present study. Bite registrations were obtained with help of
modelling waxes and positive replica prepared with dental stone and barium
powder. Intra oral periapical radiographs were taken for the same. The
radiographs obtained were scanned and analyzed by measuring tools using Sidex
is next generation software. Intercanine distance (ICD), line AB, angle ABX and angle ABY
were measured. Kruskal-Wallis test was performed to compare the bite marks of males and
females.
Results: The mean ICD of males and females
was found to be 32.95 mm and 29.84 mm respectively and statistically highly
significant with a p value < 0.001. The mean ICD, line AB and angle ABX were
found to be higher in males when compared to females.
Conclusion: Analysis of bite marks using this novel computer assisted method is a simple, reliable, easily reproducible and economical
technique with confidentiality of identity of the participants involved.
