Endodontic retreatment and apexification of a tooth previously treated with a regenerative endodontic procedure: A case report

In this case report, the treatment procedure and follow-up of a left maxillary central incisor that previously underwent a regenerative endodontic procedure is presented. After a thorough anamnesis, clinical and radiographical examination, a non-surgical endodontic retreatment was applied. Apexification treatment included intensive irrigation, Ca(OH)2 administration and finally, creating an apical plug with MTA. Follow-up radiographic and clinical examination showed healing of the periapical area and reduction of initial symptoms, keeping the tooth in function. As regenerative endodontic procedures can be recognized as the best option for permanent teeth with immature apices, there are always alternatives that can be implemented following failure.
