This clinical case report shows the repair of intraosseous coronary perforation in a maxillary canine, treated with Mineral Trioxide Aggregate (MTA), through clinical evaluation and cone beam computed tomography (CBCT) after 6 and 12 months of follow-up. Case report: The perforation occurred in the second session of endodontic treatment during the preparation of the access cavity and was located in the cervical region of the vestibular wall of the pulp chamber, communicating it with the bone tissue, at the subcristal level. Immediately after the accident, the area was cleaned with 2% chlorhexidine digluconate, the perforation was sealed with MTA Angelus and the vestibular wall of the pulp chamber was sealed with composite resin. Discussion: Intraosseous coronary perforation is an accident that occurs during the coronal opening stage, characterized by communication between the pulp cavity and the periradicular tissues, including the periodontal ligament, alveolar bone and/or gingival tissue. Sealing intraosseous perforations with bioactive materials such as MTA increases the success rate of treating these perforations. However, the long-term prognosis is not yet well established in the literature and few studies have evaluated the success of treating perforations with MTA using CBCT. Conclusion: Clinical and tomographic evaluation after 6 and 12 months showed bone healing and periodontal tissue health, demonstrating success in the treatment of intraosseous coronary perforation.
