The Role of DNA in Forensic Odontology: Part II
C. Stavrianos , A. Eliades and A. Kokkas
 
Abstract: During the last years, DNA analysis methods are applied to forensic cases. Also, forensic dental record comparison has been used for human identification in cases where destruction of bodily tissues or prolonged exposure to the environment has made other means of identification impractical, i.e., after fire exposure, aircraft inflammation or mass disasters. Teeth represent an excellent source of genomic DNA. The interest in using dental tissues as a DNA-source of individual identification falls within the particular character of resistance of this organ towards physical or chemical exterior aggressions. Because of their resistant nature to environmental assaults such as incineration, immersion, trauma, multilation and decomposition, teeth represent an excellent source of DNA material. When conventional dental identification methods fail, this biological material can provide the necessary link to prove identity. Even root-filled teeth supply sufficient biological material for PCR analysis in order to be compared with known antemortem samples or paternal DNA. DNA can be used for determination of the found remains’ identity. The identification of individuals is not the only use for dental DNA. The technique has allowed criminal investigators to link victims to crime scenes once the body has been removed and incinerated. Therefore, it is prudent for the forensic odontologist to become familiar with the fundamentals for obtaining and analyzing DNA from the oral and dental tissues. The purpose of the Part II of this report is to review of the application of the DNA technology to forensic odontology cases, the responsibilities of the odontologist and the importance of DNA extracted from oral and dental tissues and saliva.
