Resumen

El objetivo fue evaluar la resistencia al cizallamiento por extrusión y verificar el tipo de falla de postes de fibra de vidrio que han recibido diferentes tratamientos de superficie, y testar el adhesivo multiuso Single Bond Universal® (3M ESPE). Métodos: Ochenta incisivos bovinos con tratamiento endodóntico fueran aleatoriamente repartidos en cuatro grupos; Grupo I: los postes recibieron aplicación de silano; Grupo II: ningún tipo de tratamiento; Grupo III: silano y adhesivo; y Grupo IV: solamente adhesivo. Los grupos fueran sometidos a ciclaje térmico por 5.000 ciclos, las raíces seccionadas y sometidas al teste push out. Resultados: Con la silanización y la aplicación del adhesivo, la resistencia entre el poste de fibra de vidrio y la dentina ha sido significativamente menor en relación solamente la silanización. La asociación silano-adhesivo causó perjuicio a la unión. Conclusiones: La silanización por si solo es que se constituyó en el tratamiento que mejoró la resistencia unión. Fallas adhesivas fueran las más prevalentes.
