HPV is linked to an estimated 70% of oropharyngeal cancers (OPCs) in the US and outnumber cases of HPV-related cervical cancers. Not all OPCs can be detected through routine screening, making HPV vaccination a more effective primary prevention strategy. However, bridging primary and oral healthcare faces challenges due to a lack of referral networks between practices.

Researchers identified nine key study themes: three specific to the dental clinics' HPV conversations with patients, two related to community clinics' vaccine provision, and four involving the relationship between the dental and co-located community clinics. Dental clinic staff do not currently discuss HPV with patients. They are open to discussing HPV with patients but anticipate barriers that require preparation to overcome them. Community clinics have demonstrated previous success with HPV vaccination, but patients over the age of 18 face financial barriers to vaccination.
