Endodontic management of supernumerary tooth fused with maxillary first molar by using cone-beam computed tomography.
BACKGROUND
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.
