Knowledge of Iranian Dentists, Dental Specialists, and Dental Students Towards COVID-19: A Preliminary Survey of 778 Subjects

摘要

Background: COVID-19 is a serious pandemic. However, no studies worldwide have assessed the knowledge of any healthcare workers, including dentists, towards COVID-19. Objectives: Given the importance of Iran as an epicenter of this disease, this preliminary study assessed the knowledge of dentists, dental students, and dental specialists towards COVID-19. Methods: In this cross-sectional study, a questionnaire with 23 questions (three regarding sources of information and 20 regarding knowledge) was developed through a pilot study. It was distributed electronically to dental professions/students, 778 of whom completed it. Factors associated with knowledge were assessed using the chi-square test in SPSS (α = 0.05). Results: Above 70% of the responders answered correctly to all questions, except for six more technical questions, including handwashing-related questions. Age, specialization, and attendance at lectures and meetings did not play a role in grasping accurate information (all P values 0.1). Men had poorer information (P = 0.014), and the sources of information were mostly official websites and social networks (P = 0.000). Conclusions: Knowledge of dentists, dental students, and specialists towards SARS-CoV-2 is generally good, except in the case of more technical questions that need more education (especially regarding handwashing).
