Abstract

Cutaneous sinus tracts of dental origin are often initially misdiagnosed and inappropriately treated because of their uncommon occurrence and the absence of symptoms in approximately half the individuals affected. This paper reports a case describing the diagnosis and treatment of an extra-oral cutaneous sinus tract of odontogenic origin in relation to a mandibular left first molar. Non-surgical endodontic treatment was performed, and it resulted in resolution of the sinus tract and promoted peri-apical healing of the tooth involved.

Key words: Apical periodontitis, cutaneous sinus tract, necrosis pulp, non-surgical endodontic treatment.
