Abstract

Mineral trioxide aggregate (MTA) has been widely used for different reparative procedures in endodontics. The extensive use of this cement for pulp capping, apexifications, apical surgeries, and revascularization is related to its ability to induce tissue repair and to stimulate mineralization. Several research studies have tested modifications in the composition of MTA-based cements in order to enhance their clinical performance. Novel formulations have been introduced in the market with the aim of increasing flowability. Important properties such as appropriate radiopacity and setting time, color stability, alkaline pH, release of calcium ions, and biocompatibility have to be considered in these new formulations. The latest research studies on the physical, chemical, and biological properties of tricalcium silicate-based cements are discussed in this critical review.

  • Several of the ideal properties of a restorative material were present in Mineral trioxide aggregate (MTA), but others are lacking.[28]

  • The alkalinization of the medium and release of calcium ions are related to the formation of portlandite by tricalcium silicate and dicalcium silicate during the setting time of MTA.[39]
