Unfortunately, the ideal material for this purpose is yet to be found. Amalgam is the most frequently used material in apicoectomy procedure and can lead to satisfying results in many cases. IRM, super EBA and MTA (Mineral Trioxide Aggregate) are more suitable materials, and give better results in apicoectomy procedures than Amalgam. IRM and super EBA are both ZOE cements. Super EBA is less cytotoxic than IRM, suggesting that the decreased eugenol in Super EBA allows it to be less irritating. MTA gives better results when tested for leakage and biocompatibility than IRM and Super EBA, and has the ability of induction of hard tissue. A possible disadvantage that prevents MTA from being acceptable as "the ideal root-end filling material" is a long setting time that may lead to dislodgment or deformation from root end preparation. Yet, in most cases MTA serves as the best choice for a root end filling material.
