Abstract：
INTRODUCTION:Fusion is a rare occurrence, and its definitive diagnosis is of prime importance for successful root canal treatment. This case report discusses the endodontic management of a supernumerary tooth fused with a right maxillary first molar by using cone-beam computed tomography (CBCT). METHODS:Nonsurgical endodontic retreatment was performed on the supernumerary tooth. A communication between the maxillary first molar and the supernumerary tooth was repaired by using flowable resin. RESULTS:After 1 year of follow-up, there were no clinical symptoms, and the maxillary first molar remained vital. Recall radiographs and CBCT showed satisfactory healing of the periapical pathosis. CONCLUSIONS:Proper diagnosis and treatment planning for endodontic management of fused teeth by using CBCT can ensure predictable and successful results.
