Abstract BACKGROUND: Human papillomavirus type 16 (HPV16) is a common infection in the anogenital tract. HPV16 DNA detected in oral specimens has recently been identified as a risk factor for some oropharyngeal cancers. The reported prevalence of oral HPV infection from individual studies is highly variable. METHODS: We systematically reviewed and abstracted data from published studies (n = 18) that detected oral HPV DNA in 4581 cancer-free subjects to determine the pooled prevalence (and 95\% confidence intervals [CI]) of HPV16, carcinogenic HPV, and any HPV. RESULTS: 1.3\% (95\% CI: 1.0-1.7\%) of 3977 healthy subjects had oral HPV16, 3.5\% (95\% CI: 3.0-4.1) of 4441 subjects had carcinogenic HPV, and 4.5\% (95\% CI: 3.9-5.1) of 4070 subjects were positive for any HPV. Oral HPV16 accounted for 28\% of all HPV detected in the oral region. Men (47 of 1017) and women (117 of 3690) had nearly exactly the same prevalence of any oral HPV detected (4.6\% vs. 4.4\%, respectively). CONCLUSIONS: HPV-16, a common anogenital infection, was rarely detected in oral specimens. However, a small but noteworthy proportion of healthy individuals have oral HPV infections with types known to cause cancer in the oral region.
