Background
Reports of osteonecrosis and spontaneous tooth loss following herpes zoster infection of the fifth cranial are extremely rare. Only 39 previously recorded cases of post-zoster osteonecrosis have been found in the literature. The unusual feature of the case of interest to the dental surgeon is a rare complication of tooth exfoliation and maxillary osteonecrosis.
Case report
This article reports a case of 52-year-old man with herpes zoster infection of the trigeminal nerve and related alveolar bone necrosis and teeth loss. The etiology and management of herpes zoster infection associated with destructive sequelae are discussed.
Discussion
Very few cases of osteonecrosis and spontaneous teeth exfoliation secondary to herpes zoster are found in the literature. The exact mechanism by which herpes zoster induces these destructive changes in the alveolar bone and teeth cannot be proposed. As Varicella zoster virus is an aneurotropic virus, the possible provoking factors may be the infection of the nerves innervating the periosteum or the chronic inflammatory changes in the form of adverse periodontal disease and delayed healing of the extraction sockets associated with compromised host resistance.
