Non-surgical management of an extraoral cutaneous sinus tract of odontogenic origin using Nd:YAG laser: An endodontic challenge

Abstract

The extraoral cutaneous sinus tract of dental origin is an uncommon, but well-documented condition. However, several non-odontogenic disorders may also cause an extraoral sinus tract. The diagnosis is not always easy unless the treating clinician considers the odontogenic origin. The present case report discusses diagnosis and treatment of an extraoral cutaneous sinus tract of odontogenic origin in relation to a mandibular left cannine (diagnosed as asymptomatic suppurative periradicular abscess with an extraoral cutaneous sinus tract opening in the mandibular mental region). Non-surgical endodontic therapy was performed using Nd:YAG laser. To present a case report describing the diagnosis and treatment of an extraoral cutaneous sinus tract of odontogenic origin in relation to a mandibular left cannine. The patient responded well, and the cutaneous lesions healed uneventfully.
