Calcium silicate materials in endodontics

Calcium silicate materials have been recently introduced to dentistry and have found wide applications in endodontics because of their favourable biological properties. This review discusses materials that have become available commercially as well as those that are currently experimental. The compositional aspects of Mineral Trioxide Aggregate (MTA) are discussed with modifications and the development of newer materials. Based upon this information, a definition and classification for calcium silicate materials has been proposed. Calcium silicate materials have properties that make them suitable for use in endodontics. Research with hybrid materials may lead to the development of a cement with more desirable characteristics.
