Dermatological Aspects of Infections Caused By Endotoxins In Teeth With Necrotic Pulps and Apical Periodontitis
Aim: To report an uncommon case of an extraoral sinus tract of the facial region caused by a tooth with an acute apical abscess in the mandible. Case report: Established on oral examination and radiographic examination, an Acute Apical Abscess (cellulitis/phlegmon) of tooth 47 was diagnosed, which had resulted in a cutaneous sinus tract. The continuous purulent discharge of the sinus tract in the facial right region ceased after drainage and extraction of tooth 47. Conclusion: It is challenging to diagnose and identify a cutaneous draining sinus tract of dental origin. Thus, treatment of skin lesions of the face (impetigo), and neck odontogenic infections should always be considered. Clinical and radiographic dental examinations can identify the tooth involved.
