Introduction: Dental fusion is characterized by the union of two dental germs during the development stage, in consequence of the germ layer aberration in the ectoderm and mesoderm. Objective: The purpose of this study was to describe the endodontic treatment of lower incisor with supernumerary tooth. Methods: Patient sought for attention with spontaneous and severe pain in tooth #41. The dental element presented atypical crown, with aspect of fusion. By the radiographic image was observed the presence of single root and two root canals. It was determined the necessity for endodontic treatment, performed by nickel-titanium instruments. Each instrument exchange was carried out irrigation with 2.5% sodium hypochlorite solution and 17% EDTA. The filling was performed by active lateral condensation technique of gutta-percha associated to cement and complemented by thermofilling. The cone beam tomography was realized for the filling quality verification and inner anatomy architecture. The patient returned to clinical and radiographic control of 1 year with the tooth showing signs of normality. Conclusion: The dentist should develop competence and ability for the adequate diagnosis of dental anomalies, providing good conditions for the promotion of patients’ oral health.
