Comportamento de restaurações de resina composta submetidas a altas temperaturas com propósitos forenses

Abstract

The purpose of this article was to perform a gathering information of macroscopic ande microscopic changes of composite resins when submitted to high temperature, and highlight its importance in the indetification os body. After a review of articles collected from 2006 to 2014, in the Pubmed database, using the keywords "identification by restorations" and "changes by heart". After that, four groups were formed regarding temperature imposed resins: 200°C, 400°C, 600°C, 1000°C. The following methods were also evaluated for analysis of these results: X-Ray Fluorescence, the SLICE software and Spectrophotomery, comparing their advantages and disadvantages, and its collaboration on researches analyzed. It was observed that the resins have a biphasic behavior when the temperature is raised to 1000°C, under changes as expanding combustion and violatilization of the organic matrix. It was conclued that the metods should be used together and each one responds to a requirement during the analysis.
