Objectives This study aimed to assess (i) awareness of the signs and symptoms of oral cancer and its risk factors and (ii) awareness and attitudes towards oral cancer screening, in an Irish cohort. Methods A cross-sectional self-administered survey was used in a convenience sample of patients > 18 years with no cancer history attending the Dublin Dental University Hospital. The data were analysed using descriptive statistics, Pearson’s Chi-squared and Fisher’s exact tests. Results 124 responses were received. 83.7% reported knowing little/nothing about oral cancer risk factors. 12.8% did not identify smoking, 35.3% alcohol consumption, 90.5% betel nut, 35.3% age and 80.2% male gender, as risk factors. 46% were unaware that a dentist is trained to check for oral cancer. Participants were more likely to seek advice regarding a persistent oral white or red patch from their doctor than their dentist but were more likely to attend their dentist in relation to a persistent ulcer, swelling or pain. The study did not find any statistically significant relationship between gender, age, educational level and either awareness of the signs and symptoms of oral cancer and its risk factors, or with experiences and attitudes towards oral cancer screening. Conclusions The study demonstrated a lack of knowledge of the risk factors, signs and symptoms of oral cancer, and of awareness of the role of dentists in screening for oral cancer. It should be repeated in a larger cohort in non-dental settings to inform the development of oral cancer awareness programmes that address those areas where awareness is lacking.
