The Admissibility of Bite Mark Evidence

handle is hein.journals/scal51 and id is 325 raw text is: The Admissibility of Bite Mark Evidence
Bite mark analysis seeks to identify persons by comparison of their denti-
tion1 to a bite registration in flesh or other material.2 The technique is a
specialized subset of forensic odontology, the application of dentistry to
law.3 Bite mark comparisons may be offered to prove the identity of an
assailant in a criminal trial.4
This Note explores the current state of the art of bite mark analysis and
reviews California judicial treatment of the admissibility of scientific evi-
dence in general and of bite mark evidence in particular. It argues that
admission of bite mark evidence may result in the use of irrelevant, prejudi-
cial evidence by the trier of fact. In addition, it argues that the subjective
nature of bite mark evidence further hampers the jury in assessing the weight
to be accorded that evidence. The Note proposes that admissibility of bite
mark evidence be barred pending the establishment of standards of admissi-
bility by a committee of forensic odontologists.

The major fields comprising forensic odontology are as follows: (1) dental identification of
bodies of victims of crime or disaster; (2) bite mark comparison; (3) trauma and oral injury,
including, for example, expert testimony in a personal injury case; and (4) dental malpractice.

The field of identification of human remains is the most highly developed of the four areas
of interest. When a body is decomposed or mutilated, dental identification may be the only
method yielding results. Identification of a body is important for estate and insurance settle-
ment, remarriage, and homicide prosecution. L. LuNTz & P. LuLNTZ, supra note 1, at xiii. See

This Note is confined to the criminal context, in which the evidentiary arguments against
admissibility are sharply drawn. See text accompanying notes 55-69 infra.
