Figure 1: (a and b) Clinical photograph and intraoral periapical radiograph. (c) Cone-beam computed tomography scan axial slices, i – At the level of the pulpal floor showing five distinct canal orifices, ii – At the cementoenamel junction showing Y-shaped canal anatomy, iii – 1.2 mm apical to the cementoenamel junction showing J-shaped canal anatomy, iv – 4 mm apical to the cementoenamel junction showing three separate canals, v – 6.5 mm apical to the cementoenamel junction showing four separate canals, vi – Apical portion of the root showing three portals of exit. (d-i-vi) Diagrammatic representation of the complex root canal anatomy at different axial levels corresponding to the cone-beam computed tomography scan slices
