Resumen
La obturación del conducto es un paso fundamental en endodoncia para lo cual de debe ser realizada con una correcta preparación biomecánica comprendiendo todo el espacio antes ocupado por el tejido pulpar hasta alcanzar el límite CDC, precedido de una adecuada limpieza y desinfección química del sistema de conductos para su posterior obturación tridimensional. Es trascendental el sellando hermético del conducto para así evitar la microfiltración de cualquier tipo de fluido que pueda ingresar al conducto. Se realizó este estudio de laboratorio, descriptivo y experimental para comparar la microfiltración del cemento a base de hidróxido de calcio, base de resina y base de mineral trióxido agregado. Materiales y métodos: Se seleccionaron 34 dientes que cumplieron con criterios de inclusión para proceder a realizar el tratamiento endodóntico y dividiéndolos en grupos. Grupo 1: dientes obturados con Sealapex, el grupo 2: dientes obturados con Fillapex, Grupo 3: dientes obturados con Ah Plus, Grupo 4: dientes obturado sin cemento como control. Las muestras se mantuvieron hidratadas y a una temperatura de 37°C, luego de completar el proceso de fraguado del cemento se seccionaron transversalmente las raíces a 3mm del ápice. Resultados: Mediante los análisis de MEB, ANOVA y TUKEY arrojo que el Ah Plus tiene un promedio de microfiltración de 4,5 μm en foramen y 1,5 μm a 3mm del ápice y el Sealapex un promedio de 9,5 μm en foramen y 2,5 μm a 3mm del ápice. Conclusión: el cemento que presenta en promedio menor microfiltración fue el Ah Plus.
Root canal filling is a fundamental step in endodontia. Root canal filling ought to be followed by a correct biomechanical preparation comprising all the space previously occupied by the pulp tissue until reaching the dentine -root canal sealant limit, preceded by an adequate cleaning and chemical disinfection of the root canal system for its subsequent three-dimensional shutter. The hermetic sealing of the root canal is transcendental in order to avoid microfiltration of any type of fluid that can enter in it or versa. This research is considered descriptive experimental laboratory since it compares the sealant behavior within the root canal by choosing a sealant based on calcium hydroxide, based on resin and based on Mineral trioxide aggregate. Materials comprised 34 teeth were selected that met inclusion criteria to proceed with endodontic treatment and divided into groups. Consequently, the endodontic treatment is divided into 4 groups. Group 1: teeth filled with Sealapex, group 2: teeth filled MTA Fillapex, Group 3: teeth filled with Ah Plus, Group 4: teeth filled without sealant as control. The samples were kept hydrated and at a temperature of 37°C degrees, after completing the sealant setting process where the roots were cross-sectioned by 3mm from the apex. Results: The samples were examined by MEB and by ANOVA and TUKEY analysis, it showed that the resinbased sealant offers more satisfactory results than the other sealant followed by the MTA-based sealant and the calcium hydroxide-based sealant. Conclusion: The sealant with the lowest microfiltration on average was the Ah Plus
