Oral Mucosal Human Papillomavirus and Epstein-Bar Virus Rates in Patients with Dry Mouth and/or Sjögren's Syndrome in a Hungarian Cohort.

Orofacial mucosal HPV and/or EBV DNA rates did not differ statistically significantly in patients with xerostomia or hyposalivation or SS compared to healthy controls, therefore, it cannot prove the provocative role of these viruses in dry mouth and/or SS. Neither dry mouth nor SS were accompanied by statistically significantly more salivary gland alterations in HPV- and/or EBV-positive subjects; these alterations are frequent in the virus-negative cases too.
