Identification of Bodies Exposed to High Temperatures Based on Macroscopic...

Abstract


ABSTRACT. Background: Forensic dentistry in cases of incineration provides scientific elements that allow the identification of bodies, by analyzing dental organs, through the isolation of DNA obtained from the pulp as an alternative to confirm the identity of the victim. When the degree of temperature is highly elevated, dental tissues are vulnerable and therefore the DNA pulp is not salvageable, wasting resources and time by lack of standards to identify macroscopic characteristics that indicate this situation reliably. Objective: To describe the main features of teeth subjected to high temperatures and the relationship of these to the viability of their DNA, as a contribution to forensic genetic identification. Methods: A literature search for three databases were used; Pubmed, EBSCO and Google academician, 50 articles were selected in several languages, which made regarding the descriptors "cremated teeth; violence; Forensic Odontology; ID; DNA samples; dental pulp". Results: Most authors reported the resistance of dental tissues when subjected to high temperatures and others showed the success of the identification through dental comparisons. Conclusions: A successful identification evidenced by DNA extracted from bone and dental remains. The literature reviewed suggests that up to certain temperatures, can be carried out identification by forensic genetics of cremated victims by DNA contained in dental pulp. Strict national referencing was observed in the physical characteristics or incinerated dental macroscopic bodies.
