Which biodental material is the most suitable for repairing a furcation perforation?

The most suitable material for repairing a furcation perforation is mineral trioxide aggregate (MTA). MTA is specifically designed for endodontic applications, particularly in cases involving perforations. Its exceptional biocompatibility, ability to promote healing, and sealability makes it an outstanding choice in such scenarios.

MTA also exhibits a favorable tissue response, aiding in the regeneration of periapical tissues and preventing bacterial leakage, which is crucial when addressing perforations in the furcal area of a tooth. The inherent properties of MTA allow for effective sealing of the perforation while promoting the healing process, making it the gold standard for such repairs.

In contrast, while other materials like amalgam, zinc oxide-eugenol cements, and glass ionomer cements have their own advantages in certain dental applications, they lack the specific biocompatibility and sealing properties required for optimal outcomes in furcation perforations. For instance, amalgam may not bond effectively to tooth structure and can be less compatible with surrounding tissues compared to MTA. Zinc oxide-eugenol cements have limitations in their long-term sealing ability, and glass ionomer cements, though useful in some situations, do not provide the same level of tissue response and repair capability
