INTRODUCTION: the objective of this study was to describe the physicochemical changes occurring in dental tissues and materials used in a conventional endodontic treatment when subjected to high temperatures, by means of scanning electron microscopy (SEM) 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 and dentin) and dental materials commonly used in endodontic treatment (root canal gutta-percha and epoxy resin-based endodontic cement).

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 epóxica).
