Abstract
Herpes zoster is a viral infection caused by the reactivation of the varicella zoster virus (VZV) which lies dormant in sensory ganglia of a patient. The chest has many ganglia: therefore, there are many cases of VZV there. It frequently occurs especially in the trigeminal nerve of each ganglion in the sequence of the first, second, third. It is often reported that herpes zoster infection of the second and third trigeminal nerve is sometimes followed by spontaneous tooth exfoliation and sequestration. This article reports a case of a 68-year-old male who had the osteonecrosis following the extraction of canine teeth, first premolar, and first molar, after herpes zoster infection of the third left trigeminal nerve.
