The Mineral Trioxide Aggregate (MTA) was initially developed in order to seal dental fractures that may occur accidentally. The retrograde obturation to solve complications by unsuccessful endodontic treatment. Various materials have been proposed, aiming to promote the sealing of the root canal by retrograde via. The objective of this study was to review the literature on the mineral trioxide aggregate in Endodontics, regarding to the presentation, composition, physical, chemical and biological properties, clinical applications It has concluded that MTA can be used on surgical endodontic retreatment.
