Clinical Evaluation of Mineral Trioxide Aggregate in Endodontic Surgery

Objectives: to evaluate clinical results involving the use of mineral trioxide aggregate (MTA) in endodontic surgery treatment of maxillary lateral incisor with palato-gingival groove.
Methods: A 28-year-old male was referred for the treatment of left maxillary lateral incisor. Clinically, the tooth was hypersensitive to horizontal and vertical percussion, also had a negative response to sensitivity tests. Radiographic examination revealed that the incisor had a palato-gingival groove with a large radiolucent lesion periapical lesion.

The tooth was anesthetized and isolated; after the endodontic access was prepared, and then were located two canals (M-19mm, D-18mm). The canals were cleaned and shaped using hybrid instrumentation.

During surgical phase, the patient was anesthetized, a full-thickness mucoperiosteal flap was reflected, and the inflammatory lesion was thoroughly removed by curettage. The apex of the tooth was resected. A deep and wide root-end cavity was prepared and filled with mineral trioxide aggregate (MTA). The flap was repositioned and sutured. The sutures were removed after 5 days.
Results: The patient had clinical and radiographic examinations 2 and 6 months after the treatment with favorable clinical and radiographic outcomes. MTA was used as a retrofilling material mainly because of its superior sealing ability compared to other retrofilling materials as well as its higher biocompability and stimulation effect in the regeneration of periapical tissues.
Conclusions: Due to its sealing properties, biocompatibility, and hydrophilic nature, MTA is considered the best choice for a retrofilling material. Its handling characteristics are considered excellent material
