Odontogenic sinus tract to the chin: a diagnostic dilemma.
Sinus tracts of odontogenic origin most commonly open into the oral cavity but occasionally may drain extraorally. The diagnosis is more difficult when necrosis of the tooth occurs in the absence of dental caries. We report a 23-year-old man with a long-standing chronic wound on the inferior aspect of the chin that was refractory to treatment. This case demonstrates the use of a simple technique to identify a necrotic mandibular incisor tooth as the source of infection.
