title: Varicella Zoster Virus and Internal Root Resorption: A Case Report.
abstract: Herpes zoster is a viral infection caused by the reactivation of the varicella zoster virus. One of the less well-recognized maxillofacial complications is tooth root resorption. To our knowledge, this is the first case report about internal resorption associated with varicella zoster virus involving different dental quadrants. A 38-year-old woman presented with internal resorption of maxillary canine and first premolar tooth roots on the right quadrant and generalized internal resorption of second molars of both mandibular quadrants. The patient's medical history showed mild oral lichen planus and infection with varicella zoster virus (chickenpox) with severe clinical manifestations 5 years previously. The patient developed diabetes mellitus type I and hypothyroidism a short time after varicella zoster virus infection, and by the time of infection with this virus, oral lichen planus had progressed from the reticular pattern to the generalized severe erosive form. Viral etiology could also be considered in these diseases. The root canals of the affected teeth were debrided, irrigated, and dried, and calcium hydroxide paste was placed in the root canals for a week during the first treatment session. The root canals were obturated during the second session. Six-month follow-up showed improvement of oral lichen planus and resolution of widening of periodontal ligament of the affected teeth, with follow-up radiographs revealing no periapical problems. It appears some cases of internal root resorption classified as idiopathic might have viral etiology. Therefore, it is recommended that patients be questioned about a history of chickenpox and herpes zoster.
