Analysis of stability in time of marginal adaptation of endosequence root repair material on biological samples

Introduction: The introduction of mineral trioxide aggregate (MTA) and bioceramic sealers increased the success rate of endodontic surgery and perforation repair. The aim of this study was to evaluate the marginal adaptation at different times of endosequence root repair material (ERMM) in order to evaluate its dimensional stability using variable pressure-scanning electron microscope (VP-SEM). Material and Methods: Fourty-eight teeth were selected shaped up to a master apical size of 25. Then a 3mm cut perpendicular to the long axis and a retrograde cavity preparation were performed.
