Relationship of human papillomavirus with diseases of the oral cavity.

Over the last few decades, the human papillomavirus (HPV) infection has emerged as a new epidemic and become a health issue due to its involvement in several cancers affecting the cervix, the anogenital region and the oropharynx. In this review, we aim to understand and explain the distinctive features of HPV-related oropharyngeal squamous cell carcinoma based on its epidemiological data, risk factors, specific topography, HPV subtypes most frequently involved, HPV-status diagnosis, clinical behaviour, prognosis, treatment, and preventive measures. In addition, the relationship of HPV with the development of other head and neck carcinomas and benign lesions of the oral cavity will also be discussed.
