Endodontic Management of Supernumerary Tooth Fused with Maxillary First Molar by Using Cone-Beam Computed Tomography

IntroductionFusion 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).MethodsNonsurgical 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.ResultsAfter 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.ConclusionsProper diagnosis and treatment planning for endodontic management of fused teeth by using CBCT can ensure predictable and successful results.
