Resumen
El objetivo de este presente estudio fue evaluar el sellado apical de dos cementos de obturación: Topseal a base de resina epóxica y RoekoSeal a base de Polidimetilsiloxano realizado en piezas dentales monorradiculares. Para lograr este proceso se seleccionaron 25 piezas dentales clasificados en 4 grupos conformados por: 10 dientes en Topseal, 10 en Roekoseal, 2 en el grupo negativo de Topseal y 3 en el grupo negativo de Roekoseal, los conductos fueron obturados con la técnica de condensación lateral, y luego se tomaron radiografías para su evaluación. Por el método de incubación las muestras se sometieron a una temperatura ambiente de 37°C durante 4 días con la finalidad de envejecer el material, posteriormente fueron barnizadas con esmalte de uñas de diferente color para cada grupo y sumergidos en tinta china durante 72 horas. Cada pieza dental fue seccionada en cortes transversales con un disco de diamante de 0.03 mm de doble cara, y cada sección fue examinada por el microscopio operatorio para medir la extensión de penetración del tinte, y posteriormente por el microscopio electrónico de barrido para analizar el sellado y apical y el grado de expansión del material. Los resultados demostraron que la microfiltración de ambos no se pudo diferenciar significativamente
The objective of this study is to evaluate the apical sealing of two sealants: Topseal (based on epoxy resin) and RoekoSeal (based on Polydimethylsiloxane) in single-rooted teeth. In order to achieve this process, 25 dental pieces are classified in 4 groups consisting of: 10 teeth in Topseal, 10 teeth in Roekoseal, 2 teeth in the negative group of Topseal and 3 teeth in the negative group of Roekoseal. Subsequently, canals were sealed with the lateral condensation technique, and then x-rays were taken for evaluation. By the incubation method, the samples were subjected to an ambient temperature of 37°C for 4 days for aging and then varnished with nail polish of different color for each group by immersion in Chinese ink for 72 Hours. Each dental part was sectioned in cross-sections with a double-sided 0.03 mm diamond disc, and each section was examined by the operating microscope to measure the penetration extent of the dye. Finally, the electronic microscope analyzed the sealing and apical degree of the material. Findings suggest it was not possible to differentiate microfiltration of the aforementioned sealants
