case_images: The 29-year-old male patient, H.V.M. sought the graduate Dental Clinic of the Federal University of Amazonas complaining of the esthetics of the upper lateral incisors (Figure 1). On clinical examination, the presence of a fistula was observed in the vestibular region of tooth #12 (Figure 1A). The axial, sagittal, and coronal sections of the cone-beam tomography (CBCT) confirmed the presence of dens invaginatus in the upper right lateral incisor (Figures 1C-1E).

case_images: The working lengths for the mesio-buccal, mesio-lingual, disto-lingual and disto-buccal root canals were 18 mm, 18.5 mm, 17 mm, and 18 mm, respectively, confirmed by periapical radiograph using a T2 digital sensor (Microimagem, Santa Catarina, Brazil) (Figure 2B). A new periapical radiograph was performed to confirm the quality of the filling (Figure 2C).
