Internal root resorption (IRR) is described as a resorptive defect of the internal aspect of the root caused by odontoclastic activity associated chiefly with chronic pulp inflammation and trauma. An important variation to consider is the presence of a root perforation, although it is rare. This paper defines the use of CBCT in the diagnosis and combined nonsurgical and surgical multidisciplinary management and follow-up of a maxillary central incisor with perforating IRR in a 9-year-old female patient. At 3-year follow-up, clinical and radiographic findings of the case were satisfactory.
