A Case of Oral Health Management for a Patient with Extensive Ulceration of the Oral Mucosa Due to Herpes Zoster.

Oral ulcers caused by herpes zoster virus infection are commonly encountered in daily clinical practice. However, in rare cases, sepsis or viremia can occur with serious outcomes; hence, these must be managed effectively. Here, we report a case of a patient with extensive ulceration caused by varicella zoster virus infection. Antiviral treatment was started early, and oral health management was started simultaneously, with oral hygiene instructions for pain control. As a result, the patient was able to resume oral food intake and was discharged from the hospital within a week. This case suggested that oral health management comprising supportive care, with the assistance of dentists and dental hygienists, as well as antiviral therapy, are important in the treatment of oral ulcers associated with herpes zoster virus infection.
