Acutaneous dental sinus tract is a channel which leads from a dental focus of infection to drain onto the face or neck.1 These tracts tend to occur more frequently from infected mandibular teeth (80%) than maxillary teeth (20%).2 Hence, they are more common in the submandibular or submental regions of the face.3 Sinus tracts may result from localised infections, such as an infected tooth, periodontal disease, actinomycosis or osteomyelitis.4 There are numerous reports of cutaneous dental sinus tracts in the dental literature,1,4-10 but comparatively few reports in the medical literature.2,3 Patients with these lesions often present first to general practitioners rather than to dentists,1-7 possibly because they do not associate lesions of the face with teeth and often have no associated dental pain.
