case_images: An initial periapical radiography and CBCT showed the presence of DI type 2 (Oehler) in tooth #10, associated with a periapical radiolucency and internal root resorption (Figure 2). Tulsa, OK, USA) and the remaining canal spaces and the internal resorption area was obturated by warm vertical technique (Obtura II, Spartan/Obtura, Fenton, Missouri, USA). The patient was recalled after one year. The tooth had no symptoms and apical lucency was repaired and its size decreased (Figure 2C).
case_images: CBCT was used for optimal diagnosis that revealed two separate canals. The invaginated canal was almost at the center of the root but the other canal was located mesiolingually
