The Bite Mark Standard Reference Scale--ABFO No. 2.

A scale of spatial reference for bite mark photography has been developed and evaluated. The scale incorporates both linear and circular graduations to meet the diverse needs of practicing forensic odontologists in the rectification and measurement of photographically recorded bite marks. Its unique L-shaped configuration ensures accurate scaling in both the vertical and horizontal directions and facilitates the gridding of photographs to correct for distortional errors created by oblique camera angles. This paper describes the design and constructional features of the scale and offers guidelines for its effective application to bite mark photography.
