Like fingerprints, bite marks are unique to each individual. A bite mark can be examined and used to solve crime just like a fingerprint can. With bite marks however, it is difficult to pull because a forensic dentist may have to make a cast of the bite mark or take a significant amount of pictures. This is because bite marks change very quickly on the living and diseased so the examination of the bite mark needs to be immediate.
Forensics dentistry dates back to 1692 during the Salem Witch Trials when an accused "witch" was convicted by comparing their bite print with those found on victims. This type of identification is possible because the lack of or presence of dental hygiene effects the structure and appearance of teeth. As well as missing teeth, fractures, and malformed teeth all bear their own unique characteristics that show when a bite mark is examined.
Bite marks are most common in cases of sexual assault or adolescent abuse. One prominent murder trail solved by the help of forensic dentistry is the case of Ted Bundy. Bundy was a serial killer who was capture in the 1970's. He slaughtered over 100 young girls but only ever admitted to killing 30 girls. One of his last murders before being jailed consisted of a series of attacks on sorority sisters at Florida State University. His attack left two girls dead and two severely injured. One girl in particular, Lisa Levy, was bit in the left buttock. Levy's injuries where used as contributing evidence in the Chi Omega trials that put Bundy behind bars and later the electrical chair. He was sentenced to the chair in three separate trials for his serial murders.
Dental records can also help identify human remains. In many cases there are teeth left is the skulls of dumped bodies and forensic scientists are able to identify the bodies through dental records.
Forensic dentistry is an acceptable form of evidence when used in a well developed case because of how precise and accurate it can be in identifying assailants. Forensic dentists are trained to identify the bite marks for their various impressions and types. The superior training received by these dentist and strict guidelines they must follow makes this area of forensics wildly accredited.
