The initial periapical radiograph showed that there was an extra canal (Figure 1A). At the three-month follow-up, the treated tooth was functional and asymptomatic; radiographic evaluations demonstrated normal periradicular tissues (Figure 1C).

Moreover, the axial section of CBCT indicated three roots and three canals, implying that the tooth has three roots as the mesiobuccal, distobuccal, and lingual of the tooth (Figures 2 and 3).

Moreover, the axial section of CBCT indicated three roots and three canals, implying that the tooth has three roots as the mesiobuccal, distobuccal, and lingual of the tooth (Figures 2 and 3). One root canal orifice was located at the coronal root level, and CBCT showed that the canals were separated at a length of about 11 mm from the reference (Figure 3B).
