Root perforations severely affect the prognosis of the teeth. This case report presents the successful management of a complex perforation with mineral trioxide aggregate (MTA) and fiber post. MTA was used to seal the perforation site since it is regarded as one of the ideal materials for perforation repair. Following retreatment and perforation repair, the root canal was rehabilitated using fiber post and composite resin. The elimination of the clinical signs and symptoms is the primary goal of successful treatment. One-year follow-up showed healthy periodontium with no clinical signs and symptoms.
