Old Dogs Can Learn New Tricks—A New Application of the ABFO #2 Scale

In 1984 at its first Bitemark Workshop, the American Board of Forensic Odontology (ABFO) developed guidelines for the analysis of bitemark evidence. Prior to this, no standards had been established for the evaluation of bitemarks. The development of the ABFO #2 scale in 1987 gave the forensic odontologist a reproducible way to rectify and measure bitemarks that had been documented photographically. Primarily developed for the analysis of bitemark evidence, its use has expanded to encompass myriad forms of evidence. While the ABFO #2 scale can depict horizontal and vertical measurements, it is unable to depict depth accurately. The purpose of this paper is to show its successful application to three dimensions.
