Oral cavity herpes simplex virus--a risk factor to dental personnel and patients. An overview.

Herpes virus antigens were found in the sulcular epithelium of approximately 60% of patients with clinically healthy gingiva. In addition, specific antigens for herpes simplex virus (HSV) were found in the sulcular epithelial cells of patients undergoing periodontal treatment. Specific antibodies were also detected in 70-80% of the gingival fluids collected. On the basis of these data we hypothesized that the oral cavity may act as a preferential site for latent HSV. Thus, stressful events such as traumatic dental treatment and tissue damage may elicit herpetic episodes, risking dental personnel. Measures of precaution are indicated for routine dental treatment.
