Variations in canal morphology in fused teeth presents a clinical challenge when endodontic treatment is planned. Presence of pulpal remnants at the region of isthmus between the two root canals in fused teeth can compromise the success of endodontic treatment .To achieve a technically satisfactory treatment outcome, the clinician must have adequate knowledge of the internal canal anatomy and its variations to completely debride and obturate the root canal system. The aim of this case report is to present the endodontic management of left maxillary central incisor fused to a supernumerary tooth with the help of EndoVac. In the present case, we have used Endovac for establishing the presence of communication between the two root canals and for disinfecting the same.
