Cutaneous sinus tract from an impacted tooth: A case report with one step surgical treatment

Cutaneous sinuses of dental origin are well recognized pathological conditions whose pathogenesis is related to periapical or pericoronal acute inflammatory processes; nevertheless they have to be differentiated from several skin lesions of the face and neck. The case of an edentulous patient with a skin sinus in the left submandibular region from an impacted lower first molar is presented. Clinical and radiographic features of this case are reported, pathogenesis and differential diagnosis are analysed and one-step surgical treatment is described and discussed. Correlation with teeth has always to be made, also in edentulous patients, in which impacted teeth can be occasionally found. If these patients wear total dentures, a one-step surgical intervention can be performed to allow at the same time the best aesthetical results and the immediate functional rehabilitation.
