Nonsurgical endodontic management of cutaneously draining odontogenic sinus.

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 excision with eventual recurrence. This is because the primary etiology is incorrectly determined. We came across a 38 year old patient who presented with a cutaneous lesion on her left cheek with frequent purulent discharge and was not responding to systemic antibiotics. The case history, diagnosis and management of this condition is presented here.
