Dental Students' Knowledge and Attitudes About Electronic Cigarettes: A Cross-Sectional Study at One Saudi University.

There is limited information about what dental students know about the risks and effects of e-cigarettes, and there is even less information regarding their attitudes about e-cigarettes. The aim of this study was to assess dental students' knowledge, education, and attitudes regarding e-cigarettes and their confidence in discussing e-cigarettes with patients. All fourth- to sixth-year students registered at the King Abdulaziz University Faculty of Dentistry were invited to participate in this cross-sectional study conducted during a three-week period in December 2018. The focus was a comparison of never versus ever e-smokers ("ever" meaning current or former e-smokers). The response rate was 38.7% (193/498). Among the responding students, 43.2% (n=83) had ever used an e-cigarette, and 11 (5.7%) reported being current users. Almost 95% (n=183) of the total participants said they did not feel confident about their e-cigarette education in dental school. Students who had ever used an e-cigarette said they were more confident discussing e-cigarettes with patients than did students who had never used them and also demonstrated greater belief that e-cigarettes lower the risk of cancer for patients who use them as an alternative to smoking traditional cigarettes (p<0.001). This study provides evidence of a gap in dental students' attitudes and knowledge regarding e-cigarettes, making it necessary to integrate e-cigarette education into future curricula.
