Angelus MTA - A super treatment for accidents and endodontic complications

Properties of MTA

Chemical

• Release of calcium ions: allows formation of mineralized tissues.
• Highly alcaline: prevents bacterial growth.

Physical

• Low solubility: may be used directly on pulp and periapical tissues.
• Compressive strength: 44.2 MPa – may be used as base for restorations.
• Expansion after hydration: seals cavities completely.
• Setting time (15 minutes): may be used in single appointment.
• Radiopaque: allows radiographic control.

Biological

• Biocompatibility: may be used directly on living tissues.
• New formation of cement: only dental material with this capacity.
• Remineralization of dentin: allows formation of biologic barrier.
• Biologic sealing of perforations: complete healing of periapical tissues.

Ions Calcium Release

Enhances formation of mineralized tissues and provides biological seal of perforations and total repair of damaged periradicular tissues

Hydrophilic

Can be used in humid areas without losing properties

High alkalinity 

Antibacterial properties

Low solubility

Does not allow leakage

Calcium oxide

Promotes tissue biocompatibility

Aggregated oxides

Great compressive strength

High radiopacity

Higher radiopacity than that of dentin, allowing excellent radiographic visualization

Setting time of 15 minutes

Shorter setting time than similar cements
