MTA (Mineral trioxide aggregate) Angelus Dental material.
o Treatment of perforations ( root canal and fur-cation).
o Sealing of internal resorption and communicating internal resorption.
o Reverse filling in periapical surgery.
o Direct pulp capping and pulpotomy ( permanent and deciduous teeth).
o Apexification and apexigenesis.
o Intracoronal sealing prior to internal bleaching of root canal treated teeth.
o Apical plug prior to root canal filling in case of wide apex.
o Release of calcium ions: Enhances formation of mineralized tissues; provides biological sealing of perforations and total repair of damaged periradicular tissues.
o Biological action: Capable of inducing neoformation of periradicular cement.
o Hydrophilic: Dental material inductor of neoformation of periradicular cementum.
o High alkalinity: Antibacterial properties.
o Low solubility: Does not allow leakage.
o Calcium oxide: Promotes tissue biocompatibility.
o Aggregated oxides: Great compressive strength.
o High radiopacity: Higher radiopacity than that of dentin, allowing excellent radiographic visualization.
o Setting time of 15 minutes: Shorter setting time tahn similar cements.
