Information needs and preferences of dental providers for an educational package on HPV prevention: a narrative systematic review

Abstract Background Human papillomavirus (HPV) is a common virus transmitted through skin-to-skin and sexual contact, which can increase the risk of various cancers, including oropharyngeal cancer (OPC). The HPV vaccine protects against high-risk types of HPV and may reduce the rate of oral HPV infections and help prevent cancer. Given their role in screening for head and neck cancer, dental providers are well placed to promote the HPV vaccine to their patients. We aimed to systematically summarise the global evidence in relation to dental providers' knowledge of HPV and the HPV vaccination programme, willingness to engage in HPV promotion activities, and preferences for dental staff educational packages. Methods A comprehensive search of six databases were undertaken to identify relevant studies published from database inception to October 2024. Studies were eligible if they reported evidence in relation to dental providers knowledge of HPV and the HPV vaccination programme, willingness or practices related to HPV promotion activities, or preferences for dental providers educational programmes. No restriction by language was applied. Data from eligible primary studies were uploaded to QSR Nivo14 software to support data organisation and reporting, with an initial coding framework developed and then refined. Results Forty-four eligible studies were identified. Significant global variation in HPV knowledge was observed, with more limited knowledge evident in Asia based studies. Despite good knowledge among dental providers that the HPV vaccine may reduce the risk of HPV-driven cancer, many misconceptions were identified, including a lack of understanding regarding eligibility for the HPV vaccination programme and about how the virus is transmitted. There was general support among dental providers for education packages, despite some discomfort in discussing topics related to sexual transmission of HPV with patients and parents. Preferences for these packages were generally interactive with resources to aid HPV education patients. Conclusions Information needs among dental providers and a reluctance to engage in discussions around the sexual transmission of HPV appears to impede effective HPV promotion efforts in dental settings. Development of educational packages to address this could improve HPV awareness and support efforts to improve HPV vaccination uptake globally.
