title: Repair of a large furcation perforation: a four-year follow-up.
abstract: This case report describes the management of a large furcation perforation in a maxillary first molar. Although the majority of the pulpal floor was destroyed and the mesiobuccal root was damaged, an attempt was made to repair the defect and restore the tooth. An absorbable gelatin sponge matrix was placed, and the defect was repaired with gray ProRoot mineral trioxide aggregate. Subsequently the endodontic treatment was completed; the tooth was restored and was later used as a fixed partial denture abutment. A 55-month recall showed no evidence of periodontal breakdown, no symptoms, and complete healing of all periradicular lesions.
