Case Report: A 21-year-old female patient with no known chronic systemic disease was referred to the endodontics clinic for evaluation of a possible odontogenic source of infection after being hospitalized for septic shock. Based on a detailed medical and dental history, clinical examination, pulp sensibility tests, periapical and panoramic radiographs, and cone-beam computed tomography findings, the pulpal diagnosis for tooth #47 was established as pulp necrosis, while the apical diagnosis was chronic apical abscess, accompanied by intraoral and extraoral sinus tract formation. Following chemomechanical preparation and intracanal medication with calcium hydroxide–chlorhexidine, root canal treatment was completed using gutta-percha and a resin-based root canal sealer. Clinical and radiographic follow-up examinations revealed marked healing of the intraoral and extraoral sinus tracts, a reduction in the size of the periapical lesion, and osseous healing. Conclusion: This case highlights the importance of considering a possible odontogenic source in the differential diagnosis of persistent cutaneous sinus tracts in the head and neck region and documents a favorable clinical and radiographic outcome following nonsurgical endodontic treatment. </p>}, number={2}, organization={Bu çalışma için herhangi bir kurum veya kuruluştan mali destek alınmamıştır.}
