case_images: The radiographic examination revealed a radiolucent lesion with ill-defined borders in the periapical region of tooth #25 (Fig. 3A-C). The extraoral sinus tract had healed (Fig. 3 D). Thus, the root canal was filled with gutta-percha and AH-26 sealer with the cold lateral compaction technique (Fig. 3 E).

case_images: At the 2-month follow-up session (Fig. 4 A, B), the patient had no complaint of pus discharge from the extraoral sinus tract, and the opening had been completely healed. At the 5-month recall session (Fig. 4 C, D), the extraoral sinus tract opening had completely healed, and the periapical lesion had shrunk on the radiographic examination. At the 1-year follow-up (Fig. 4 E, F), the respective tooth was asymptomatic, and the periapical lesion had completely healed.

case_images: She had undergone a computed tomography scan (Fig. 5A). The extraoral examination revealed a dense mass in the check area (Fig. 5B). On the intraoral examination, her maxillary right first premolar had an incomplete previous RCT with an open access cavity without any temporary restoration (Fig. 5C). The radiographic examination revealed that tooth #5 had a small periapical radiolucency and PDL widening (Fig. 5D). In the second treatment session, the significant healing of the sinus tract opening on the cheek was noticed (Fig. 5E). The patient had no clinical or radiographic signs/symptoms at the 3-month follow-up (Fig. 5F, G).

case_images: Periapical radiography of the left mandibular quadrant was requested, which revealed that tooth #17 had an incomplete RCT and a radiolucent periapical lesion (Fig. 6A, B). RCT was accomplished, and the root canals were filled using gutta-percha and AH-26 sealer with the cold lateral compaction technique (Fig. 6C, D).
