What are the public health benefits of community-based education in dentistry? A scoping review

Aim: To examine what is known about the public health benefits of community-based education in dentistry.

Method: A scoping review was conducted using a modified Arksey and O'Malley framework. Database searches were undertaken on PubMed, Medline via Ovid, CINAHL via EBSCO and ERIC, and a grey literature search was undertaken on OpenGrey, Medlar, BASE and the British Library. Reference lists of included studies were also searched. Although no formal quality assessment was undertaken, observations on methodological rigour were recorded.

Results: In total, 31 studies from nine countries met the inclusion criteria. Most were from high-income countries. Methodologies of included studies varied: quantitative (n = 17); qualitative (n = 5); mixed methods (n = 6); and reviews (n = 3). Several potential public health benefits were reported: increased access to dental services (including improvements in their availability, affordability, acceptability, accessibility, and accommodation); improved awareness/health literacy of students and communities; and improved clinical outcomes. The overall quality of the evidence was low and had little community engagement.

Conclusion: Notwithstanding the methodological limitations of the included studies, several potential public health benefits have been associated with community-based education in dentistry. Rigorously designed, methodologically appropriate research is needed, which should include engagement with communities.
