ABFO PRESIDENT GARY BERMAN’S MESSAGE:

 

Forensic Odontology is once again headline news. Unfortunately this time it is not for our service to country, community and victim’s families after a mass disaster. Rather it is for the controversy in the field of bitemark analysis performed my many of our Diplomates and others.

 

Back in 1976 the American Board of Forensic Odontology was organized under the auspices of the National Institute of Justice. This was in response to the need for forensic scientists unequivocally qualified to provide essential professional services for the Nation’s judicial and executive branches of government. The ABFO is comprised of individuals who are nationally and internationally recognized experts. The ABFO is accredited by the Forensic Specialties Accreditation Board (FSAB) as a forensic specialty offering board certification to qualified dentists.
The objective of the Board is to establish, enhance, and revise as necessary, standards of qualifications for those who practice forensic odontology, and to certify as qualified specialists those voluntary applicants who comply with the requirements of the Board. In this way, the Board aims to make available a practical and equitable system for readily identifying those persons professing to be specialists in forensic odontology who possess the requisite qualifications and competence.

 

The Board has long recognized an ongoing need for continuing education and research, and to this end sponsors both outside research and workshops for interested Forensic Odontologist.
The American Board of Forensic Odontology (ABFO) is firmly and irrevocably dedicated to provide true and accurate information to ensure the administration of justice. Since its founding in the mid-1970s, the members have worked to improve accuracy and eliminate bias in their results. Forensic dentists have been instrumental in the identification of literally thousands of people who perished in fires, floods, accidents, and homicides and whose families without these services might never have received the closure they deserve; they have also assisted in uncounted situations of identification of unknown remains. Forensic dentists have also become involved in the analysis of patterned injuries caused by teeth, “bitemarks”. The ABFO is acutely aware of cases involving bitemark analysis in the past that have contributed to several individuals wrongly being convicted. The ABFO has updated and improved its recommendations for appropriate investigation, evidence collection procedures and methods of bitemark analysis and its “Bitemark Methodology Standards and Guidelines” is continuing to evolve.

 

This document contains:
Methods to Document Human Bitemark Evidence
Human Bitemark Analysis Guidelines
Bitemark Terminology Guidelines
Bitemark Case Review Guidelines
Guidelines for Investigative and Final Bitemark Report.

 

It is the ABFO’s belief that Bitemark Analysis when performed with appropriate analysis, based on continuous study and scientific research with conservative conclusions can be extremely helpful in the legal system.

 

Drs. Silver and Souviron write in their book, “Dental Autopsy, 2009”
• “A bitemark can show and demonstrate pain
• A bitemark can be offensive as well as defensive
• A bitemark usually demonstrates violence
• A bitemark may produce a permanent injury……, It elevates a simple battery to aggravated battery…
• A bitemark can, in certain cases, be distinctive in both class and individual characteristics and may yield a dental profile of the biter….
• A bitemark can, in some cases, help to determine the age of the biter (child vs adult)
• A bitemark or marks can be aged. In cases of child or elderly abuse, multiple bites over time will show a pattern of abuse…
• A bitemark may give a clue as to when it occurred in relation to the time the victim died…..
• A bitemark may give information as to the position of the biter and victim when the bite was inflicted…..
• A bitemark may or can yield salivary DNA to help with the identification of the suspect.”

 

Even the N.A.S. Report, “ Strengthening Forensic Science: A Path Forward” stated on page 176, “…can sometimes reliably exclude suspects”.
Several ABFO members have assisted in high-profile exoneration cases and are continuing to do so.

 

As found in our ABFO Diplomates manual, “Terms assuring unconditional identification of a perpetrator, or identification “without doubt”, are not sanctioned as a final conclusions in an open population case by the ABFO. The ABFO does not support a conclusion of “THE BITER” in an open population.”

 

In order to improve the study of bitemarks the ABFO developed a decision tree to assist practitioners in the proper selection and pathways of analysis in bitemark analysis. Drs. Pretty and Freeman designed a study with the assistance of some ABFO members providing the case materials to evaluate the reliability of Step 1 of a proposed revision to the bitemark analysis and comparison decision tree. This was presented at the AAFS meeting in Orlando in 2015.

 

Statistical analysis of the results of that study showed poor overall agreement, utilizing Step 1, among the individuals who participated in the survey. Post analyses of the results indicate that the design of the survey and the design of Step 1 of the decision tree may be flawed, and that the ABFO guideline term of “suggestive” of a human bitemark may be the root cause. The ABFO in reaffirming its commitment to ensure accuracy in bitemark analysis is currently revising and updating the terminology used in the decision tree to ensure reliable results by forensic dentists. Drs. Freeman and Pretty will be continuing their preliminary research after new terminology is approved the Diplomates of the ABFO.

About the ABFO

Mission

The objective of the Board is to establish, enhance, and revise as necessary, standards of qualifications for those who practice forensic odontology, and to certify as qualified specialists those voluntary applicants who comply with the requirements of the Board. In this way, the Board aims to make available a practical and equitable system for readily identifying those persons professing to be specialists in forensic odontology who possess the requisite qualifications and competence.

 

Purpose

The need to identify forensic scientists unequivocally qualified to provide essential professional services for the Nation’s judicial and executive branches of government has long been recognized. In response to this professional mandate, The American Board of Forensic Odontology was organized in 1976 under the auspices of the National Institute of Justice.

 

The ABFO is comprised of individuals who are nationally and internationally recognized experts. The ABFO is accredited by the Forensic Specialties Accreditation Board (FSAB) as a forensic specialty offering board certification to qualified dentists.
