El propósito de este estudio fue evaluar la microfiltración de cuatro materiales de obturación retrógrada. Cuarenta y dos dientes humanos extraídos unirradiculares fueron instrumentados y obturados. A cada diente se le realizó resección radicular y preparación retrógrada con ultrasonido. Los dientes fueron divididos en 4 grupos de 10 cada uno, los cuales se obturaron con PRO ROOT®, Súper-EBA®, CPM® MEDIX y CPM® EGEO. Se usó un control positivo y uno negativo. La microfiltración apical fue determinada usando tinta china. Los dientes fueron diafanizados y se midió la microfiltración de la tinción por medio de un microscopio estereoscópico a una magnificación de 20X. El análisis estadístico mostró que el Súper-EBA®, CPM® EGEO y PRO ROOT® presentaron menor microfiltración que el CPM® MEDIX.
Palabras clave: Microfiltración; materiales de obturación retrógrada
The purpose of this study was to evaluate the microleakage of four root-end filling materials. Forty-two single canal root extracted human teeth were cleaned and shaped. Each tooth was apically resected and the apex was prepared ultrasonically. The teeth were divided into 4 groups of 10 roots each and filled with PRO ROOT®, Super-EBA®, CPM® MEDIX and CPM® EGEO. Positive and negative controls were used. Apical leakage was determined using ink. The teeth were demineralized and transparent and the amount of dye microleakage was measured using a stereoscopic microscope at 20X magnification. Statistical analysis showed that Super-EBA®, CPM® EGEO and PRO ROOT® leaked significantly less than CPM® MEDIX.
Keywords: Microleakage; root-end fillings
