This paper aimed to evaluate the impact of an oral health programme targeting prisoners in eastern Saudi Arabia. The reach, effectiveness, adoption, implementation and maintenance (RE-AIM) strategy was used as the evaluation framework to assess both process and outcome. This annual programme included four stations: an interview, an educational session, dental examination and treatment. Programme indicators included the number of prisoners reached, percent improvement in oral health practices, teeth present in the mouth and percent reduction in dental treatment needs. A non-experimental pre- and post-programme evaluation design was implemented. Prisons in eastern Saudi Arabia were visited once a year from 2016 to 2019. The evaluation used primary data collected during the visits in the form of clinical examination and surveys. The number of beneficiaries increased from 270 to 634, and three cities within the Eastern province were covered. The percent of inmates who smoke and consume sugary drinks decreased by 24 and 30%, respectively; however, there was a 25% reduction in regular toothbrushing using a fluoridated toothpaste. The long-term outcomes showed an improvement in the overall oral health condition and treatment needs: periodontal treatment needs and surgical procedures were reduced by 91 and 79%, respectively. The programme was successful based on the RE-AIM framework. This is the first sustainable oral health programme targeting prison inmates in the Middle East. The findings indicate that the oral health programme had positive effects on prisoners' oral health and achieved its objectives. Such programmes can help address health disparities among populations.
