Surgical Endodontics on Teeth 2.4 and 2.5 with Symptomatic Apical Periodontitis Following Failed Previous Surgery

Clinical and radiographic examination revealed symptomatic apical periodontitis affecting teeth 2.4 and 2.5. Tooth 2.4 was associated with a sinus tract, indicative of chronic infection with acute exacerbation. Both teeth had previously undergone surgical endodontic treatment, which had failed, resulting in persistence of the periapical pathology. Given the persistence of the lesion and the previous surgical failure, a decision was made to perform a secondary surgical endodontic procedure aimed at eliminating the infected tissue and achieving a proper apical seal. After local anesthesia with lidocaine containing epinephrine 1:50,000 to ensure optimal intraoperative hemostasis, a full-thickness mucoperiosteal flap was elevated to expose the surgical…
