Access bur and an Endo Z bur (Dentsply Tulsa, Tulsa, OK) under rubber dam. A C-shaped configuration extending from buccal end to palatal end of the pulp chamber was observed and its continuity could also be detected by DG 16 explorer (Figure 1).
Shows typical C-shaped configuration at the coronal level. 2b. C-shaped configuration at the middle third. 2c. Canal continuing as single canal at the apical third. 2d. & 2e. Canal terminating at the single foramen at the apical end
