• Abstract: Literature reports that fusion is a developmental anomaly characterized by the union of two adjacent teeth. Coronal union is observed, however, the roots of the dental elements are independent. Endodontic treatment in fused teeth is challenging, and the dentist must be attentive in conducting the therapy. The objective of this study is to evaluate, through a case report, the endodontic treatment of a dental element affected by fusion . A patient was treated, diagnosed with pulp necrosis and fusion between two adjacent dental elements (27 and 28). In the first session, anesthesia, access surgery, absolute isolation, irrigation with 2.5% sodium hypochlorite, odontometry, instrumentation with Prodesign S 2 rotary files at working length, drying, and insertion of intracanal medication (calcium hydroxide) were performed. In the second session (after 15 days), the intracanal medication was removed and the root canals were obturated . This case study concludes that the pathological process was resolved, and the function and aesthetics of the fused teeth were preserved, thus avoiding the need for tooth extraction.
