Fiber post retrieval and furcal perforation repair in maxillary molar: A case report with one year follow-up

Abstract

INTRODUCTION. Furcal perforation is a complex endodontic complication that can jeopardize treatment outcomes. Accurate diagnosis and appropriate management are essential to prevent periodontal breakdown and tooth loss.AIM. This case report aims to present the non-surgical management of a furcal perforation in a maxillary first molar caused by fiber post-placement, emphasizing the role of CBCT, biomaterials, and magnification.MATERIALS AND METHODS. A 33-year-old female presented with mild pain and swelling in the upper left maxillary region. Clinical examination revealed a sinus tract near the cervical area. Cone Beam Computed Tomography (CBCT) confirmed a furcal perforation with extrusion of a fiber post. The fiber post was carefully removed under magnification using ultrasonic tips. Hemostasis was achieved, and a calcium hydroxide dressing was applied to the perforation site to promote healing. After 10 days, the site was sealed with mineral trioxide aggregate (MTA). The tooth was then permanently restored following core buildup.RESULTS. At the one-year follow-up, the tooth was asymptomatic. CBCT showed bone healing at the perforation site, and the sinus tract had resolved. Clinical and radiographic evaluation confirmed successful tissue repair and preservation of periodontal health.CONCLUSIONS. This case highlights the importance of early detection and precise management of furcal perforations. The use of CBCT, magnification, and MTA enables predictable, non-surgical repair. Even in delayed cases, MTA provides effective sealing and promotes long-term clinical success.
