case_images: The preoperative radiograph revealed radiopacity in the pulpal chamber and at the apical third of one of the roots (Figure 1). While the former was indicative of a restorative material, the latter on the other hand disclosed a fractured/separated instrument from the previously initiated therapy (Figure 1).

case_images: Once the fractured file was bypassed completely (Figure 2), sequentially larger files (size 20 K-files) were introduced seamlessly till the size 25 SS K-files working their way to the apex, as described earlier.

case_images: Drying of the canals was made certain with absorbent paper points (Dentsply Sirona), following which the master cone fit was checked and confirmed on a radiograph (Figure 3).

case_images: Obturation of the prepared canals was attained by the single cone gutta-percha (Dentsply Maillefer) technique with AH Plus resin-based sealer (Dentsply DeTrey, Konstanz, Germany) as the sealant (Figure 4).
