MTA Applications

MTA is a biocompatible filling material frequently used in endodontics (root canal treatment). Developed in the 1990s, this material is preferred especially in root-end treatments, perforation (drilling) repairs, and pulp capping. MTA accelerates tissue healing. It is long-lasting and durable. It has a high chance of saving the tooth. Its hardening time may be long (3-4 hours). Its cost is higher than other filling materials.

Application

The area is numbed with local anesthesia. Infected tissues are cleaned and the area is disinfected. MTA is made into a paste consistency and placed in the application area. It is allowed to harden in a humid environment and closed with a temporary filling.

Properties

• Biocompatible: It is compatible with body tissues and is not toxic.
• Antibacterial Effect: It reduces the risk of infection by preventing bacterial growth.
• High Sealing: Provides excellent insulation in closing the canals.
• Secretes Calcium Ions: Promotes tissue healing and supports hard tissue formation.
• Moisture Resistant: It can harden even in a humid environment.

In Which Cases Is MTA Used?

• Apexification (Root End Closure): It allows the root end to be closed in teeth with incomplete root development.
• Perforation Repair: It is used in the repair of perforations in the root or root end that occur during root canal treatment.
• Pulp Capping (Direct/Indirect): It is applied in procedures aimed at protecting the pulp (nerve tissue).
• Retrograde Filling (Surgical Endodontics): It is used to close the end part of the canal after root end resection (cutting).
• Apical Barrier: It creates a barrier at the root end in the treatment of underdeveloped roots.
