Oral Cancer Risk Perceptions in Dental Attending Smokers

Previous work has shown the benefit of written information for those at high risk of oral cancer, especially for tobacco smokers. Objectives: This study investigated two hypotheses: that a patient information leaflet (PIL) would enhance risk perceptions, and second that these improvements would be associated with smoking behaviour. Methods: Patients (N=995) attending 20 general dental practices in Northern Ireland were invited to participate, 28 refused (response rate= 97%). Patients were randomised into two groups. The experimental group received a PIL and then completed a self-report questionnaire, whereas the control group followed same procedure without the PIL. Measures included two items to assess risk perception and questions to obtain a self-reported smoking history. Results: Usable data were available from 944 patients; mean (SD) age= 42 (15), 65% female. Risk perceptions of oral cancer were minimally effected by the PIL (p=.023). This effect was demonstrable in smokers. Smokers were sixteen (95%CI: 8 to 30) times more likely to believe that they were at greater risk of oral cancer than non-smokers. Conclusions: The risk perceptions of smokers can be raised with written information and this may improve willingness to have a check for oral cancer in primary health care services.
