title: Surgical resolution of an aggressive iatrogenic root perforation in a maxillary central incisor: a case report with a 4-year follow-up.
abstract: The prognosis of teeth with root perforations depends on several factors, including size, location, and time since occurrence. Root perforations are clinical situations that can be solved by either nonsurgical or surgical approaches. The purpose of this article is to present a case of an aggressive iatrogenic root perforation in a maxillary right central incisor solved surgically using mineral trioxide aggregate (MTA). Even in an unfavorable situation, MTA was able to induce new bone formation and reestablish gingival and periodontal health, as confirmed in follow-up examinations at 2 and 4 years.
