Endodontic Management of Cutaneously Draining Odontogenic Sinus using Shoe Lace Technique.

Odontogenic cutaneous sinus tract is a rare but well-documented condition. It is usually misdiagnosed as a local skin lesion and maltreated by systemic antibiotics and/or surgical intervention. This is because the primary etiology is incorrectly determined. We came across a 30-year-old patient who presented with a cutaneous lesion of dental etiology in the submental region with frequent purulent discharge which was not responding to systemic antibiotics. The case history, diagnosis and management of this condition using surgical endodontics are presented here.
