A health promotion intervention to improve oral health of prisoners: results from a pilot study

PURPOSE: Prisoners have poorer oral health than the general population. Good oral health is essential for both social and physical well-being. For prisoners, poor oral health is also related to drug use after release, whereas good oral health is related to successful reintegration into society. The purpose of this study was twofold: to examine the effect of an intervention based on motivational interviewing (MI) on prisoners’ oral health-related behavior and to assess if the intervention is a good fit for this population. DESIGN/METHODOLOGY/APPROACH: In total, 16 prisoners in a Norwegian prison were offered a brief MI-based intervention focusing on changing their oral health-related behavior. An oral examination was also performed and the prisoners received a small package containing oral hygiene aids. Two weeks later, a second oral examination and a semi-structured interview were conducted to explore the effect of the intervention and examine the prisoners’ responses to the intervention. Qualitative data analyzes were guided by thematic analysis. FINDINGS: The findings indicate that the intervention had positive effects on both the prisoners’ motivation to use oral health-related behavior and their performance of oral health-related behavior. The findings also indicate that the intervention was well adapted to the target population. ORIGINALITY/VALUE: This is one of the first studies that explore the effect of an intervention in improving prisoners’ oral health and bridges a knowledge gap in the literature. The findings may increase the understanding of how dental services should be organized and offered to provide dental health care to this vulnerable group.
