Resumen

Antecedentes: La formación de la capa híbrida debe ser proporcional a la capacidad de los cementos para retener con éxito postes de fibra de vidrio en el interior del conducto preparado endodónticamente. Objetivo: Medir el espesor de la capa híbrida en los tercios coronal y apical as usar cementos autograbadores de uno y dos pasos. Métodos: Se realizó un estudio experimental con 30 premolares humanos que se trataron endodónticamente y se asignaron a tres grupos. Se cementaron postes de fibra de vidrio con tres cementos siguiendo las instrucciones de los fabricantes. Se realizaron cortes coronales y apicales y se cuantificó el grosor de la capa híbrida por microscopía electrónica de barrido. Los datos se analizaron con las pruebas estadísticas H de Kruskal-Wallis y U de Mann-Whitney (p<0,05). Resultados: El promedio del grosor de la capa híbrida fue de 0,74 mm con Multilink N® (grupo 1), 0,24 mm con RelyX Ultimate® (grupo 2) y 0,03 mm con RelyX U200® (grupo 3) (p = 0,0092). Los promedios en los tercios coronal y apical fueron: 1,29 mm y 0,19 mm para el grupo 1; 0,33 mm y 0,14 mm para el grupo 2 y 0,26 mm y 0,23 mm para el grupo 3, diferencias que fueron estadísticamente significativas (p = 0,043). Conclusiones: El espesor de la capa híbrida formada con el uso de los cementos de dos pasos fue mayor que con el cemento de un solo paso, especialmente en la porción coronal.
