En una muestra aleatoria de 30 piezas dentarias premolares, uniradiculares con características similares de forma y tamaño. Se realizó el respectivo tratamiento de conducto con la técnica de retroceso, luego se procedió a la desobturación y a la restauración con EFC, EFV y ET, respectivamente en 3 grupos de 10 piezas, las cuales se le sometieron a fuerzas compresivas verticales hasta el momento de la fractura en una máquina universal de pruebas en Kg., a una velocidad de 2pulg/segundo. Hallándose los siguientes resultados en piezas dentales restauradas con: - EFC presentan una resistencia promedio de 207 - EFV presentan una resistencia promedio de 181 - ET presentan una resistencia promedio de 202 Concluyéndose que los EFC presentaron mejor resistencia a la compresión seguido por los ET y los EFV, aunque las diferencias no fueron estadísticamente significativas a un 0,01 de confianza.
