“…This treatment consists of exposing the involved apex, resecting the root end, preparing a class I cavity, and filling this cavity with a rootend filling material. Investigators have reported that insufficient 295 apical seal is a major cause of surgical endodontic failures (1,2); root-end cavities should be filled with biocompatible substances that prevent egress of potential contaminants into the periradicular tissues.…”

This study investigated the marginal adaptation of mineral trioxide aggregate (MTA) as a root-end filling material, compared with commonly used rootend filling materials by scanning electron microscopy (SEM). Eighty-eight single-rooted freshly extracted human teeth were cleaned, shaped, and obturated with gutta-percha and root canal sealer. Following root-end resection and cavity preparation, the root-end cavities were filled with amalgam, Super-EBA, Intermediate Restorative Material (IRM), or MTA. Using a slow-speed diamond saw, 40 roots were longitudinally sectioned into two halves. Resin replicas of resected root ends of the remaining nonsectioned roots were also prepared. After mounting longitudinal sections of roots and resin replicas of resected roots on aluminum stubs, the distance between the test rootend filling materials and surrounding dentin was measured at four points under SEM. Examination of the original samples showed numerous artifacts in the longitudinal sections of the specimens. In contrast, the resin replicas of resected and filled root ends had no artifacts. Statistical analysis of data comparing gap sizes between the root-end filling materials and their surrounding dentin shows that MTA had better adaptation compared with amalgam, Super-EBA, and IRM.

ResumenUno de los objetivos del material de obturación retrograda colocado en un tratamiento de apicectomía es proporcionar sellado apical que inhiba la migración coronaria de antígenos hacia los tejidos perirradiculares. Muchos materiales son utilizados para este fin, sin embargo, a la fecha no se ha encontrado ningún material que satisfaga todos los requerimientos de un material ideal de obturación retrograda. La presente investigación se hizo con el propósito de hacer un análisis comparativo de las propiedades de sellado apical de tres materiales de obturación retrograda: amalgama de plata, ionomero de vidrio y MTA (agregado de trioxido mineral), ante el proceso de filtracion de la bacteria Enterococus Faecalis y el tiempo empleado para filtrar vía coronaria hacia la zona perirradicular. La filtracion fue comprobada al virar el caldo de glucosa rojo de fenol, en el cual fueron sumergidos los apices de los dientes de estudio, a una temperatura de 37ºC. Los resultados demostraron que la frecuencia de especimenes que filtran en tiempos mayores a 70 días es significativamente más alta para los casos de cemento MTA, que para los otros dos materiales. AbstractOne of the aims of a root-end filling material placed in an apicectomy treatment is to provide apical seal that can inhibits the coronary migration of antigens to perirradicular tissues. Many materials are used for this end; however, to date there has not been any material that satisfies all the requirements of an ideal material. With the purpose of making a comparative analysis of the apical sealing abilities of three root-end filling materials: silver amalgam, glass ionomer and MTA (mineral trioxide aggregate), in the leakage process of Enterococcus Faecalis bacteria and the time used for it to leak via coronary toward the perirradicular area, the present investigation was made. Leakage was proven when veering the fenol red glucose, in which the apexes of the sample teeth were submerged, to a temperature of 37ºC. The results showed that specimens that leakage in longer than 70 days were significantly higher for the cases of cement MTA than for the other two materials. Odontología Sanmarquina
