In the management of large radicular cysts, especially on an aesthetic region, it is essential to obtain information by means of three-dimensional images. They provide proper definition of the extension and of the relationship with important anatomical structures. This case report aims to describe the role of the Cone Beam Computed Tomography (CBCT) on diagnosis, endodontic approach, surgical treatment, as well as follow-up of a large radicular cyst. The patient came to the Dental Clinic of the State University of Maringá, showing asymptomatic enlargement in the anterior maxilla. Tooth 11 was non-vital. CBCT presented a cystic lesion, measuring about 20.69×17.18×16.75 mm, in the periapical region of 11, with involvement of the left nasal fossa floor and incisive canal. Based on clinic and tomographic examinations, the provisional diagnosis was radicular cyst. The treatment plan consisted of endodontic treatment of 11 and enucleation of the lesion, under local anaesthesia. Histopathological examination confirmed the diagnosis. The patient was followed-up clinically and radiographically for two years. We concluded that CBCT contributed a lot to the success of this case, as an important tool for proper diagnosis, surgery, endodontic treatment, as well as follow-up.
