COMPARACIÓN DE LA FUERZA DE ADHESIÓN DE DOS CEMENTOS ENDODÓNTICOS A BASE DE SILICATO DE CALCIO. ESTUDIO IN VITRO
Contenido principal del artículo
Resumen
Objetivo: El propósito de este estudio fue la comparación de la fuerza de adhesión de dos cementos a base de silicato de calcio Bio C Sealer y MTA Fillapex y de otro cemento de resina epóxica AH Plus. Metodología: se dividieron en tres grupos los cementos del estudio para realizar técnica de condensación vertical en la obturación de 30 raíces de premolares inferiores, de las cuales se seccionaron 5 discos de cada una, para ser sometidos a pruebas de expulsión por medio de la máquina de ensayos universal, para registrar la fuerza de adhesión de los cementos analizados en megapascales (MPa). El análisis estadístico se hizo por medio de la prueba de ANOVA de una vía y Bonferroni. Resultados: se demostró que el cemento Bio C Sealer (5,30 MPa) obtuvo la mayor fuerza de adhesión, seguido por AH Plus (3,40 MPa) y MTA Fillapex (1,39 MPa) que tuvo los resultados más bajos de adhesión, existiendo diferencias estadísticamente significativas entre los grupos. Conclusión: el cemento biocerámico Bio C Sealer tiene mayor fuerza de adhesión a las paredes de los conductos radiculares.
