Herpes zoster is a common viral infection, the oral soft tissue manifestations of which are widely known and recognized. Reports of spontaneous tooth exfoliation and jaw osteonecrosis following herpes zoster infection in the distribution of the trigeminal nerve are extremely infrequent and sporadic, with only 39 cases being reported in the literature. We report an additional case of mandibular osteomyelitis and spontaneous tooth exfoliation following herpes zoster infection, which occurred in the left mandible of a 70-year-old diabetic man; however, our case also showed CMV co-infection. The role of CMV in the pathogenesis of the osteonecrosis remains uncertain. Awareness of the possibility of CMV co-infection in various oral diseases including oral ulcers, Kaposi's sarcoma, and herpes zoster infections especially in immunocompromised patients is important, since spread of the CMV can easily occur to other sites with potentially fatal consequences. Early diagnosis can lead to effective treatment and prevention of complications.
