title: Hypothesis: the gingival tissue as a reservoir for herpes simplex virus.
abstract: The reservoir site of Herpes simplex virus (HSV), from the primary infection until reactivation and in between recurrences was found to be in the dorsal roots of the trigeminal ganglion or in the sensory root ganglion. However, the triggering of viral genome in the ganglion does not exclusively explain the recurrences and appearance of skin lesions. Other sites cannot, therefore, be excluded, and virus may well be occult also in extraneural tissues. Herpes virus antigens were found by us in the sulcular epithelium of approximately 60% of patients with clinically healthy gingivae; we therefore hypothesised that the epithelial cells might act as the preferential site for latent HSV. In order to prove this assumption, viral genome should be traced in cells of oral tissues, and efforts should be made to rescue virus.
