Abstract: Introduction: Extraoral sinus tracts of endodontic origin may often be misdiagnosed as lesions of non-odontogenic origin and may result in healing failure or unnecessary treatments. Case Report: An 18-year-old male patient presented with the chief complaint of facial lesion on the chin since 2 weeks and gave history of trauma 7 years back. On examination, a cutaneous lesion was seen in the submental region and complicated crown fracture was seen with tooth 41. Tooth 31 did not respond to cold test and the electric pulp test. Radiographic examination revealed a definitive periapical radiolucency associated with 41 and 31. Gutta percha tracing of the sinus tract was done. Nonsurgical endodontic treatment was initiated on tooth 41 and 31 and calcium hydroxide intracanal medicament was placed in the first visit and changed in subsequent visits over the course of 3 months. When adequate periapical healing was observed, obturation was done and follow up visit at 6 months showed complete healing of extra oral sinus tract. Conclusion: A possible dental origin should be suspected while diagnosing cases of infected facial lesions and in most cases, a non-surgical approach to treatment is sufficient.
