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).
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
