MTA-Angelus Reparative Cement is an endodontic reparative cement, containing mineral trioxide aggregate (MTA). It is indicated for the treatment of lateral and furcation perforations, apexification, internal resorption, pulpotomy, pulp capping, and apexogenesis. 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. The powder is packaged in a re-sealable vial with liquid (distilled water) in a dropper bottle. Unused powder may be kept for future use. Each kit contains five, 1 g vials of powder with a measuring scoop and a 3 mL bottle of liquid. MTA-Angelus was evaluated by 26 consultants in 201 uses. This reparative cement received a 91% clinical rating.
Consultants used MTA-Angelus Reparative Cement for a variety of applications and reported it was easy to mix and handle. The texture is less gritty than other reparative cements. Working time is appropriate for all indications, and placement requires no special carriers. Manipulation and clean-up of the cement were reported to be better than similar products. Consultants would have preferred a quicker setting time. The white color was universally accepted for use under esthetic restorations, and radiopacity was rated excellent.
Viscosity of the cement can be adjusted by varying the powder-to-liquid ratio.
