Bite-Mark Analysis
Definition
A pattern-comparison discipline in which a forensic odontologist attempts to link a bite wound on a victim to the dentition of a suspect. The foundational claim, that human dentition is unique and reliably transferred, has not been independently validated to a standard that supports source attribution.
- Primary application
- Comparing patterned skin injuries to suspect dental characteristics
- Key limitation
- Underlying assumptions about skin distortion and dental uniqueness lack full validation by controlled research
Common questions
What does a forensic odontologist do with bite-mark evidence?+
A forensic odontologist examines patterned injuries or impressions made by teeth and compares them to a suspect's dental characteristics. The goal is to determine whether the suspect's teeth could have made the mark, either including or excluding them as a possible biter.
How reliable is bite-mark analysis in court?+
Bite-mark analysis is far more contested than dental identification for victim remains. The assumptions underlying the method, particularly about how skin distorts when bitten and whether each person's bite pattern is truly unique, have not been fully validated by controlled research.
What evidence does a bite-mark examiner work with?+
Examiners typically compare patterned skin injuries (like marks on a victim's body or an object) with a suspect's dental characteristics, such as tooth shape, spacing, alignment, and wear patterns. The quality and clarity of both the injury and the dental impression directly affect analysis.
