"Human anterior dental patterns have not been shown to be unique at the individual level" "Those patterns are not accurately transferred to human skin consistently" "It has not been shown that defining characteristics of those patterns can be accurately analyzed to exclude or not exclude individuals as the source of a [sic] bitemark" Recently, the scientific foundation of forensic odontology, and especially bite mark comparison, has been called into question. A 1999 study by a member of the American Board of Forensic Odontology found a 63% rate of false identifications. However, the study was based on an informal workshop during an ABFO meeting which many members did not consider a valid scientific setting. In February 2016, the Texas Forensic Science Commission recommended that bite mark evidence not be used in criminal prosecutions until it had a more firm scientific basis. That same year, the President's Council of Advisors on Science and Technology declared that bite mark analysis had no scientific validity. An investigative series by the Chicago Tribune entitled "Forensics under the Microscope" examined many forensic science disciplines to see if they truly deserve the air of infallibility that has come to surround them. The investigators concluded that bite mark comparison is always subjective and no standards for comparison have been accepted across the field. The journalists discovered that no rigorous experimentation has been conducted to determine error rates for bite mark comparison, a key part of the scientific method. Critics of bite mark comparison cite the case of Ray Krone, an Arizona man convicted of murder on bite mark evidence left on a woman's breast. DNA evidence later implicated another man and Krone was released from prison. Similarly, Roy Brown was convicted of murder due in part to bite-mark evidence, and freed after DNA testing of the saliva left in the bite wounds matched someone else. Although bite mark analysis has been used in legal proceedings since 1870, it remains a controversial topic due to a variety of factors. DeVore and Barbenel and Evans have shown that the accuracy of a bite mark on the skin is limited at best. Skin is not a good medium for dental impressions; it is liable to several of irregularities present before the imprint that could cause distortion. Also, bite marks can be altered through stretching, movement, or a changing environment during and after the actual bite. Furthermore, the level of distortion tends to increase after the bite mark was made. Both studies suggest that for the bite mark to be accurately analyzed, the body must be examined in the same position it was in when the bite occurred, which can be a difficult if the not impossible task to accomplish. Bite mark distortion can rarely be quantified. Therefore, bite marks found at the scene are often analyzed under the assumption that they have undergone minimal distortion.
== Dental Age Estimation == When trustworthy birth records are either unavailable or contested, Dental Age Estimation (DAE) is a scientific method for estimating an individual's age. It is frequently used in criminal investigations, immigration and asylum proceedings, and disaster victim identification, among other forensic, medico-legal, and humanitarian contexts. Because of their consistent development and resilience to environmental and postmortem alterations, teeth are regarded as extremely dependable markers. In addition to skeletal and chronological age, dental age is evaluated using a variety of techniques based on the age group and available data. In 2026 the volume Dental Age Assessment: A Global Perspective was published by Springer Publishers, comprising 20 chapters reviewing established and emerging techniques and reflecting current international practices and future directions in the field.
