Impact of educational intervention regarding COVID-19 on knowledge, attitude, and practice of students before dental school re-opening

BACKGROUND AND AIM: Lack of knowledge on COVID-19 among people and healthcare staff significantly impacts late management and its rapid transmission. Dental students must be aware of the exact preventive instructions due to their close contact with patients and clinical work in the dental setting during the pandemic. This interventional study aimed to investigate the effectiveness of designed educational content regarding COVID-19 on Iranian dental students’ knowledge, attitudes, and practices at Alborz University of medical sciences. MATERIALS AND METHODS: A total of 88 dental students were investigated in this study. Educational content was designed based on the clinical guidelines regarding COVID-19 in dentistry. The content was presented to dental students as a three-hour webinar. In addition, the online, validated questionnaire was obtained from the students as pre, post, and follow-up surveys. RESULTS: A statistically significant difference between students’ knowledge, attitudes, and practices were obtained before and after the intervention and the follow-up survey. 48.58% improvement in knowledge score, 6.37% in attitudes, and 17% in practice scores were observed. CONCLUSION: Although this educational intervention significantly improved the knowledge, attitude, and practice of dental students, additional education and clinical training are mandatory for effective and safe dental practice management in future crises.
