METHODS: in vitro, two human premolar teeth were subjected to temperatures of 200°C and 400°C respectively, with the purpose of standardizing a technique for the observation of physical and chemical changes in dental tissues (enamel anddentin) and dental materials commonly used in endodontic treatment (root canal gutta-percha and epoxy resin-based endodontic cement). RESULTS: both the tissues and the dental materials analyzed in this pilot study presented great resistance to high temperatures without significantly changing their macrostructure; therefore, the physical changes (dimensional stability, cracks, crevices, fractures,texture, carbonization) and the chemical ones (constituent chemical elements) may turn out to be identifiable and associated with each specific temperature range by means of SEM and spectrophotometric analysis.

MÉTODOS: in vitro, se sometieron dos dientes premolares humanos a 200 y 400 °C respectivamente, con el fin de estandarizar una técnica para la observación de los cambios físicos y químicos en los tejidos dentales (esmalte y dentina) y de los materiales de uso odontológico empleados comúnmente en endodoncia(gutapercha y cemento endodóncico a base de resina cambios físicos (estabilidad dimensional, fisuras, grietas, fracturas, textura, carbonización) y químicos (elementos químicosconstituyentes) pueden llegar a ser identificables y asociarse a cada rango de temperatura específico a través del análisis MEB y espectrofotométrico.
