What Do Dental Students Know About E-Cigarettes? A Cross-Sectional Survey from One Palestinian Dental School.

Owing to the vital role played by dentists in patient education and due to the growing popularity of e-cigarette use among the younger population, this cross-sectional study aimed to assess the use, knowledge, beliefs, and attitudes toward e-cigarettes among dental students. A cross-sectional questionnaire was given between March and June of 2024 to undergraduate dental students in the Faculty of Dentistry at the Arab American University in Palestine. A 32-item questionnaire with five sections, namely demographics, smoking habits, knowledge, beliefs and attitude, and education about e-cigarettes was sent to all appropriate participants (N = 1050). The response rate was 31% (N = 325). About 11.7% of the respondents were current e-cigarette smokers. The two most commonly cited reasons for initial use of e-cigarettes were curiosity (52.8%) and a desire to quit conventional smoking (27.8%). The average knowledge score was 6.63 (3.08) out of 12, demonstrating a generally inadequate level of knowledge about e-cigarettes. Conventional cigarette smokers were more knowledgeable about e-cigarettes than non-smokers (OR = 1.928; 95% CI: 1.061-3.505;
