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.
牙根穿孔牙齿的预后取决于几个因素，包括穿孔的大小、位置以及穿孔发生后的时间。牙根穿孔是一种临床情况，可通过非手术或手术方法解决。本文的目的是介绍一例上颌右中切牙医源性侵袭性牙根穿孔的病例，该病例通过使用三氧化矿物凝聚体（MTA）进行手术治疗。即使在不利的情况下，MTA仍能够诱导新骨形成并重建牙龈和牙周健康，这在2年和4年的随访检查中得到了证实。
