Bangladeshi dental students' knowledge, attitudes and behaviour regarding tobacco control and oral cancer.

Bangladesh's oral cancer incidence is high. Dentists can participate in tobacco control. The aim of this study is to explore tobacco use, tobacco control attitudes and oral cancer knowledge among Bangladeshi dental undergraduates. This cross-sectional study used the Global Health Professional Students Survey and the Humphris Oral Cancer Knowledge Scale. One hundred eighty six questionnaires were analysed, a 79% response rate. Tobacco use, oral cancer knowledge, attitudes towards tobacco control and the dentist's role in tobacco cessation varied significantly between colleges and by gender. Oral cancer knowledge and positive tobacco control attitudes did not influence tobacco use. There is a global problem in preparing dental students for a holistic, integrated approach to oral cancer prevention.
