A scoping review of interventions to improve oral health in prison settings

Objective: To describe the characteristics of oral health interventions implemented in prison settings and explore the barriers and facilitators towards implementation. Methods: Following Joanna Briggs Institute scoping review methodology, six databases were searched including Medline (R), Emcare, Embase, AMED, Cochrane and PsycINFO. A total of 978 studies were returned and screened. The inclusion criteria were those studies conducted in a prison population, with an intervention to address oral health and published since 2000. Results: Ten studies published between 2008 and 2021 were included. All were conducted in high-income countries. Three intervention types were identified: health education (n = 5), teledentistry (n = 3) and screening or triaging (n = 2). The barriers and facilitators to successful implementation were grouped into a framework of four overarching concepts. These included prison environment, population makeup, compliance and staffing. Clinical Significance: Evidence suggests that oral health interventions in prisons are focused on improving access to services and oral health messages. A range of drivers including the prison environment, staffing levels, recruitment and intervention compliance influence implementation and the success of interventions.
