Reliability of canine tooth while analysing bite mark using metric method.
Impressions of both maxillary as well as mandibular arches of 50 consenting volunteers were taken and dentition casts were prepared. The bite mark impression and the dentine measurements were compared using Microsoft Excel Software, by comparing each parameter of the bite mark with the similar parameter in the dentition cast of the volunteer. The relation of all parameters with canine measurement was observed.
The findings resulted in 14 true positives, and exclusion of canine as a parameter resulted in 18 true positives. Observations showed an improvement in result from 28 to 36%.
We conclude that exclusion of canine as a parameter in bite mark analysis gives more positive identifications.
