Inter disciplinary approach of chronic periapical lesion with extraoral sinus tract opening on to the nasal floor: A case report

Dental pulp and periodontium are closely related and the pathway of communication between these structures helps in determining the progress and prognosis of the disease. Though periapical lesions can be managed non-surgically, surgical intervention is needed in cases of recalcitrant chronic periapical lesions that do not respond to conventional endodontic therapy. This case report highlights the surgical management of chronic periapical lesion of endodontic origin with an unusual location of the extra-oral sinus on the nasal floor.
