case_images: Periapical tissues appeared normal (Figure 1A). A control radiograph was taken (Figure 1B).  Then, the tooth was temporized and returned to the referring dentist for permanent restoration (Figure 1C).The patient was asymptomatic at the two-year follow-up, with a radiograph examination showing a normal periapical appearance (Figure 1D).

case_images: Since the canals were enlarged up to the level of the first curvature using SX to S2, the coronal part of the master GP cone, which has a 4% taper, cannot fit well to the coronal canal wall (Figure 2A).  The coronal space was backfilled using melted GP (Fast-fill, Eighteeth) and packed 1 mm below the level of orifices. (Figure 2B) schematically depicts the procedure of the CVC technique.

case_images: Radiographically, the tooth presented with a mesial root periapical lesion that extended from a partially resorbed mesial apex coronally along the distal surface of the mesial root into the furcation (Figure 3A). Optibond universal (Kerr Endodontics) and Multicore Flow core material (Ivoclar, Schaan, Liechtenstein) were placed as the permanent coronal restoration for the subsequent crown preparation (Figure 3B).  Evidence of the periapical lesions on both roots remained visible but were significantly smaller (Figure 3C).
