case_images: 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).

case_images: 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).

case_images: 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).
