4. DEFENITION FDI defines forensic dentistry as:
That branch of dentistry which, in the interest of justice, deals with proper handling of dental evidence, and with proper evaluation and presentation of dental findings.

5. DEFENITION
Forensic Odontology is the study of teeth for the investigation of identity and crime.
Forensic Dentistry is the application of dental knowledge to those criminal and civil laws that are enforced by police agencies in a criminal justice system.

6. Basis for Forensic Dentistry
The THEORY behind forensic dentistry is that no two mouths are alike (even identical twins are different), & teeth like tools, leave recognizable marks.

7. The Founder Of Modern Forensic Dentistry
Cuban-born Dr. Oscar Amoedo wrote the first essay on forensic odontology in 1898 in Paris, Entitled "Dental Arts and Legal Medicine" which provided the first images and text related to the identification of unknown bodies.

8. History of Forensic Odontology

9. 1849 – Mass deaths at Vienna Opera House Fire
Paul Revere was the first forensic dentist in the United States because he identified fallen revolutionary soldiers.
First body identified
using teeth was (Lollia Paulina)through discolored front tooth.

10. First Identification Committee
Norway established the first forensic odontology identification committee in 1945 to investigate crime scenes with multiple victims.
Each committee consisted of a police officer, a dentist and a doctor working together to identify the deceased.

11. How To Become a Forensic Odontologist ???
Most forensic odontologists are practicing as dentists.
The minimum degree requirement is (DDS).
specialized training is a must.
The American Board of Forensic Odontology (ABFO) certifies forensic odontologists.
Most are members of professional organization.

12. Organizations of Forensic Odontology
Bureau of Legal Dentistry (BOLD).
American Society of Forensic Odontology (ASFO).
International Organization for Forensic Odonto-Stomatology (IOFOS).
American Academy of Forensic Science (AAFS).

13. Association with Law Enforcement
In case requiring identification of postmortem identity or bite-mark analysis
Evidence and analysis collected may be applied directly to an open case or be entered into a database for future identification

14. The Importance of Forensic Odontology
Transport accidents.

15. The Importance of Forensic Odontology
Vehicles & house fires.

16. The Importance of Forensic Odontology
Gunshot trauma.

17. The Importance of Forensic Odontology
Individual Identification.

18. The Importance of Forensic Odontology
Mass Disaster Identification:
is an unexpected event that causes severe injury and death to a number of people.
TYPES

19. Natural Mass Disaster
Earth quakes e.g. Tsunami

20. Accidental Mass Disaster
Air craft & train crashes, building fires.

21. Intentional Mass Disaster
Bombing of buildings: e.g. World trade center.

22. Challenges In Mass Disasters
Large number of human remains.
Fragmented and burned remains.
Difficulty in determining who was involved in the disaster.
Acquisition of meaningful medical and dental records.
Legal, jurisdictional and political issues.

23. Role of Forensic Odontologist
Identification of human remains through dental records and assisting at location of mass disaster.

24. Role of Forensic Odontologist
Assessment of cases of abuse (child, spousal, elder).

25. Role of Forensic Odontologist
Assisting investigative agencies to identify corpses, human remains & fragmented bodies.

26. Role of Forensic Odontologist
Assessment of bite mark injuries & compare bite marks with the teeth of a suspect and present this evidence in court as an expert witness.

27. Role of Forensic Odontologist
Presenting evidence in court.

28. Role of Forensic Odontologist
Age estimation.
Determining race, occupation, previous dental history and socioeconomic status of unidentified human beings.

29. Role of Forensic Odontologist
The evidence and analysis collected may be applied directly to an open case or be entered into a database for future identification.

30. Methods for Identification
Identity.
Traditional methods.
Physical features.
Dental apparatus.

31. Identity
Characteristics by which a person may be identified.

32. Traditional Methods
Visual recognition, personal property.

33. Physical features
Acquired & inherited features.

34. Dental apparatus Resistant to post mortem decomposition.
Most material used by dentist for restoring teeth are also resistant to post mortem destruction.

35. Phases of Forensic Identification
Data collection & ante-mortem investigation:
All available dental records
Original radiographs
Dental models
Cephalometric films
Phase 3
Preliminary Evaluation:
Nature of death
Reason of dental input
Phase 1
Comparison & conclusion:
All postmortem & ante-mortem information
obtained & charted
Results compared
Conclusion reached
Phase 4
Postmortem Exam:
Facial & intraoral photograph
Oral structures
Radiographs
Dental impressions
Phase 2

36. Identification POSITIVE PRESUMPTIVE Dental records comparison.
Radiological.
Fingerprints.
DNA.
Bite marks.
Salivary swap.
Dental impression.
Lip-prints.

37. Can you tell the differences of these bite marks?
