Abstract
|
|
|
|
A cutaneous sinus tract or cutaneous fistula of dental origin occurs when purulent products of dental pulp necrosis spread along the path of least resistance from the root apex to the skin on the face. As many patients present with only skin problems and without toothache, it is frequently misdiagnosed as a cyst, abscess, pyogenic granuloma, actinomycosis, squamous cell carcinomas, and so on. Incorrect diagnoses lead to invasive procedures and long-term antibiotic therapy. We present 2 cases of recurrent suppurative facial dimpled nodules. Both of the cases were referred to the maxillofacial department, where the non-restorable teeth were extracted, and root canal therapy was performed. Lesions may persist for long periods before the correct diagnosis is made and the odontogenic source is treated appropriately. With early correct diagnosis, patients can be protected from unnecessary and ineffective antibiotic therapy or surgical treatment. Herein, we report 2 cases of a cutaneous sinus tract of dental origin.
