Background: Oral health care professionals are well positioned to contribute to the prevention of human papillomavirus (HPV)-related oropharyngeal and other HPV-related cancers through engaging patients in conversations about HPV vaccination. This scoping review evaluates evidence regarding oral health care provider knowledge of, and discussion related to, HPV prevention, transmission, and associated risks, including oropharyngeal cancer. This review outlines relevant barriers to, and facilitators of, this knowledge and discussion. In addition, to determine the potential population that could be reached by an oral health care provider for a conversation about HPV vaccination, this review evaluates the prevalence of HPV vaccination as well as dental visits in a US population.

Types of studies reviewed: Four databases were systematically searched (MEDLINE [PubMed], EMBASE, APA PsycInfo, Cumulative Index to Nursing and Allied Health Literature). Studies written in English and conducted in the United States were eligible. Eligibility criteria were not restricted to publication year or oral health care provider type. Behavioral Risk Factor Surveillance System 2018 data were analyzed to evaluate the prevalence of HPV vaccination and dental visits among patients aged 18 through 49 years.

Results: After duplicate record removal and second-stage screening, 32 full-text articles were retrieved, and data were independently extracted by 2 reviewers. Twenty-four studies were included in this review. Knowledge regarding HPV prevalence, transmission, disease processes, and risks varied. In general, discussions related to HPV in dental settings were infrequent. Facilitators to improve knowledge and discussion included guidance from professional dental organizations, education, and communication skills. Behavioral Risk Factor Surveillance System data showed that most people who are not vaccinated have visited their oral health care providers in the past year, highlighting the potential role of oral health care providers regarding discussion of HPV and promoting awareness and acceptance of vaccination.

Conclusions and practical implications: This review indicates that discussions related to HPV were infrequent in the oral health care setting, which may be related to lack of knowledge and communication skills among oral health care professionals; however, evidence exists supporting the interest of oral health care professionals in improving vaccine uptake to prevent oropharyngeal cancer.
