Evolution of MTA cement - a literature review

Abstract

The mineral trioxide aggregate MTA is a revolutionary material in endodontics since 1990 several studies have shown its use and its clinical applications, with high performance and long-term success, its initial development for the repair of perforations was soon expanded for apicification, pulpotomies and obturation retrograde in paredodontic surgeries. It was initially described in 1993 by Mahmoud Torabinejad from an analysis of Portland cement, since then it is considered the gold standard as the material of choice for sealing perforations in view of its excellent physical-chemical properties, radiopacity and biocompatibility. This article aims to review the existing literature, seeking to assess the history, characteristics and composition of the mineral trioxide aggregate MTA.
