Herpes zoster in an immunocompetent adolescent - A case of rare occurrence.

Herpes zoster is an acute viral infection caused by the reactivation of the varicella zoster virus. It occurs commonly in immunocompromised adults. Odontalgia may be an early prodromal symptom when herpes zoster involves the oral and maxillofacial region, which lays significant emphasis on the role of a dentist in early diagnosis and treatment of the infection. Herpes zoster infection commonly affects adult and elderly patients and is very rare in children. This article shows cases of herpes zoster infection in a 14-year-old immunocompetent boy who presented with dental pain as a prodromal sign. Herpes zoster may occur in children and thus should be considered in the differential diagnosis of acute multiple ulcers occurring in that population.
