Maillefer, Ballaigues). Master cone radiograph (Figure 1(c)) was taken followed by obturation by lateral condensation technique using Gutta percha (Dentsply, Maillefer, Ballaigues) and AH plus sealer (Dentsply, DeTrey, Germany). CBCT and preoperative radiograph. Core buildup was done with composite (Para-core, Coltene, Whaledent Inc, USA) and the patient was advised a full coverage crown (Figure 1(d)).

Complete morphology of the root canal system was obtained in coronal, axial, and sagittal sections of 0.2 mm thickness. CBCT (Figure 2) revealed 4 canal orifices which merged into two canals apically in the distal root and two separate canals in the mesial roots.
