A rare case report and appraisal of the literature on spontaneous tooth exfoliation associated with trigeminal herpes zoster

Background

Reports of post herpetic maxillofacial complications have been very rarely documented in the literature that includes periapical lesions, calcified and devitalized pulps, resorption of roots, osteonecrosis, and spontaneous exfoliation of teeth. The atypical feature of the case of concern to the dental surgeon is the rare complication of spontaneous tooth exfoliation following herpes zoster.

Case report

This case reports a male patient of age 47 years who reported to the Department of Periodontology with the chief complaint of mobility in the left upper central incisor. Patient history revealed herpes zoster infection that began 11 days earlier along with underlying diabetes mellitus condition. We hereby report a known diabetic patient with history of herpes zoster infection who presented with rare complication of spontaneous tooth exfoliation involving the maxillary division of the trigeminal nerve.

Discussion

Limited number of cases has been reported in the literature regarding spontaneous teeth exfoliation secondary to herpes zoster. The exact pathogenesis regarding the spontaneous exfoliation of teeth in herpes zoster patient is still controversial. Thus, an oral health care provider should be aware of this rare complication while managing a case of tooth mobility with the previous history of herpes zoster of trigeminal nerve.
