Abstract

Background/Aims
Periodontitis is a chronic inflammatory disease affecting almost half of adults in the UK and is a leading cause of tooth loss. Current evidence suggests that periodontitis could be a causal risk factor for rheumatoid arthritis (RA) onset and progression, and periodontal treatment may improve disease activity in patients with established RA. Earlier periodontal intervention in individuals at-risk of RA could provide a unique opportunity to delay progression or prevent it entirely. This study aimed to explore the perceptions of oral health among individuals at-risk of developing RA and the perceived acceptability of preventive periodontal treatment.

Methods
This was a qualitative interview study employing a phenomenological approach. Anti-CCP positive at-risk individuals with musculoskeletal symptoms but no synovitis were recruited from the Leeds CCP cohort. Periodontal assessments and treatment were delivered by a dentist and/or oral hygiene therapist. Individual semi-structured interviews were conducted via video or telephone between March-June 2022. Interviews were audio-recorded and transcribed verbatim. Data were analysed using reflexive thematic analysis.

Results
Nineteen participants (ten women; age range 35-70) were interviewed. All had been offered periodontal assessment and treatment; four declined and nine had periodontal treatment. Three themes were identified: i) understanding risk; ii) oral health perceptions and experiences; iii) oral health treatment and maintenance. The majority of participants lacked awareness of the association between oral health and the risk of developing RA, and perceived lack of knowledge of this link among dentists. Preference for information provision relating to oral health as a risk factor varied extensively between participants. Negative perceptions towards dental appointments were common. Many participants identified the cost of dental treatment as an issue and expressed difficulty in accessing NHS dentists. Participants discussed oral health issues such as bleeding and sore gums, chipped and weak teeth, infections, and missing teeth. However, oral health was less of a priority when compared to comorbidities that had a bigger impact on daily life. Participation in a clinical trial involving preventive periodontal treatment was perceived to be acceptable for most participants. Facilitators included the personal benefits of being able to reduce risk, access a dentist, and not having to pay for treatment. Participants with dental phobia highlighted that seeing the same dentist at every visit was important. Perceived barriers included the location and time of appointments.

Conclusion
The impact of poor oral health may not be well understood by individuals at-risk of RA. Information relating to this risk factor should be tailored to the individual. Whilst periodontal disease is common in individuals at-risk of RA, seeking dental treatment can be hindered by dental phobia, treatment cost, or shortage of NHS dentists. A clinical trial involving preventive periodontal treatment is potentially acceptable for individuals at-risk of RA.
