Bioceramic reparative cement.
MTA-Angelus Cement is an endodontic reparative cement, containing mineral trioxide aggregate (MTA). Calcium ions are released that promote the formation of a dentin bridge when used for pulp capping and promote biological healing and the formation of root cement in cases of root perforations. MTA-Angelus is designed to be used under moist conditions, as it absorbs water and forms a gel, and then solidifies. MTA-Angelus has an initial setting time of 10 minutes and a final setting time of 15 minutes.
