Radiographic evaluation of the referrer's preoperative radiograph, which was provided by the patient revealed a periapical lesion and bone loss mostly around the distal root and in the furcation area, and also slight periodontal ligament widening around the mesial root as well as a likely strip-perforation [Figure 1].

A size 20 finger plugger (Mani, Japan) was used to compact the cold ceramic; enough space for postplacement in the distal canal was allowed [Figure 2]. The postoperative radiograph showed a satisfactory root canal filling and complete perforation obturation with cold ceramic, although a small amount of material was extruded through the perforation site [Figure 2].
