The specimens were observed through Digital Photography (DP), Stereomicroscopy (SM) and Scanning Electron Microscopy (SEM).Results: it was observed that passive RFID microchips have capacity to withstand high temperatures maintaining their macrostructural integrity, but they were observed cohesive and adhesive fractures that disrupt the mechanisms of adhesion between the dental tissues, the composite material and the microchip, and impairs its correct operation beyond 300 °C.Conclusions: passive RFID microchips implanted in human molars with a resin restoration resist the action of high temperatures without altering their macrostructure, however they only operated up to 300 °C, which eventually may contribute to the processes of forensic identification in case of burned, charred and incinerated bodies.

    Resumen
    Objective: to assess In vitro behavior of a passive RFID microchip implanted in human molars and subjected to high temperatures to determine their resistance and performance.Methods: an experimental In vitro study was done to evaluate the behavior of a passive RFID microchip (VeriChip™) implanted in 10 human molars with a composite restoration (Filtek P90™ Silorane 3M-ESPE®) in class I occlusal cavities and class V vestibular cavities and subjected to high temperatures (100 °C, 200 °C, 300 °C, 400 °C and 500 °C), in order to determine their resistance and performance.

    Objetivo: valorar el comportamiento In vitro de un microchip RFID pasivo implantado en molares humanos y sometidos a altas temperaturas para determinar su capacidad de resistencia y funcionamiento.Materiales y métodos: estudio experimental In vitro que evaluó el comportamiento de un microchip RFID pasivo (VeriChip™) implantado en diez molares humanos a través de una restauración en resina (Filtek P90™ Silorane 3M-ESPE®) en cavidades oclusales clase I y vestibulares clase V y sometido a altas temperaturas (100 °C, 200 °C, 300 °C, 400 °C y 500 °C), con el fin de determinar su capacidad de resistencia y funcionamiento. Los especímenes fueron observados a través de Fotografía Digital (FD), Estereomicroscopio (EM) y Microscopio Electrónico de Barrido (MEB).Resultados: se observó que los microchips RFID pasivos tienen capacidad de resistir a las altas temperaturas al conservar su integridad macroestructural; sin embargo, se observaron fracturas cohesivas y adhesivas que alteran los mecanismos de adhesión entre los tejidos dentales, la resina y el microchip, y el correcto funcionamiento de este último a partir de los 300 °C.Conclusiones: los microchips RFID pasivos implantados en molares humanos a través de una restauración en resina resisten la acción de las altas temperaturas sin alterar su macroestructura. No obstante, solo funcionaron hasta los 300 °C; lo que, eventualmente, podrá contribuir con los procesos de identificación forense para el caso de cadáveres quemados, carbonizados e incinerados.[Moreno F, Moreno SM, Garzón H.
