Figure 1: (a) Preoperative periapical radiograph of case1; a 24-year-old male with history of impact trauma to the anterior upper jaw which was referred for retreatment of tooth #9. Clinically, buccal and palatal swellings were present, and tooth 9 was sensitive to palpation and percussion. Radiographically, a large periapical radiolucent lesion was present on tooth #9, teeth #9 and 8 were immature, and both were inadequately obturated. (b) Postoperative radiograph after retreatment of teeth #9 and 8, and placement of CEM cement apical plug in tooth #9 and MTA apical plug in tooth #8, warm vertical obturation of remained canal spaces in both teeth with gutta-percha and sealer, and permanent coronal restoration of access cavities with bonded composite resin. (c) Follow-up radiograph at 18 months after treatment. Both teeth were functional and asymptomatic. The periapical lesion of tooth #9 completely healed
