Released in 2015, MTAFlow™ cement (Ultradent Products Inc. Considering the importance of the ideal flowability that a repair material should have to reduce the difficulty of handling and delivering, a high-plasticity MTA cement was developed with the aim of improving these characteristics. A shorter setting time and better washout performance were desired, so the clinician could feel confident that the product had set before the procedure was finished and wouldn’t be flushed out by water or blood. The multipurpose use of MTA demanded the development of improved formulations. Despite such good characteristics, the first generation of MTA repair material presented some drawbacks, including difficult handling properties, a long setting time, and an unfriendly delivery method. MTA has been recognized as a bioactive material that is hard tissue conductive, hard tissue inductive, and biocompatible, so the applications of this material have been rapidly expanding in dentistry. The first formulation of MTA (1995) was composed of gray Portland cement with the addition of bismuth oxide powder as a radiopacifier. 1 Primarily composed of tricalcium silicates, MTA cements are radiopaque materials that form a self-setting calcium silicate hydrate mix when manipulated with water. Tricalcium silicate hydraulic cement materials such as the well-known mineral trioxide aggregate (MTA) are biocompatible materials with high-sealing ability and have been used for various reparative purposes in dentistry, including root-end filling, sealing perforations, treating open apices, and direct pulp-capping.
