Rehabilitation of facial dermatologic lesion of dental origin in a pediatric patient

Odontogenic cutaneous sinus tract (OCST) of the facial region is rarely found and mostly misdiagnosed because of its variable cutaneous manifestations with the absence of obvious dental symptoms. Usually, patients consider such lesions of dermatologic origin instead of dental origin, and hence, seek its treatment from medical specialists which results in recurrence due to inappropriate treatments without considering the dental etiology, dental history, intra-oral examination, and dental radiographs. The current article presents a case report about chronic OCST at mental region (chin) of the face in a 10-year-old male patient. The source of infection was completely eliminated by endodontic therapy using calcium hydroxide Ca(OH)2 and by conservative surgical debridement of periapical necrotic granulation tissue without excising the extra-oral sinus-tract orifice. The appropriate dental treatment resulted in the resolution of symptoms and rehabilitation of facial esthetics without any recurrence in follow-ups. Thus, the patient's quality of life was improved after successful dental treatment as evaluated by Child's Perception Questionnaire 8–10.
