Oral health practitioners' knowledge, attitude, and awareness about coronavirus: A systematic review and meta-analysis

BACKGROUND: Oral health practitioners are at the frontline of infection, particularly with respiratory viruses such as the novel coronavirus. Knowledge, awareness, and attitude of these workers are considered important in preventing and controlling the outbreak. This study aims to review the literature to provide a better understanding of the status of dentists and other oral health practitioners' knowledge, attitude, and awareness about COVID-19. METHODS: A systematic review was conducted through Web of Science, PubMed, Scopus, and ProQuest up to May 6, 2020. All the knowledge, attitude, and practice studies on oral health workers about respiratory contagious outbreak the same as severe acute respiratory syndrome, Middle East respiratory syndrome, and COVID-19 were included in the meta-analysis. RESULTS: A total of eleven studies were included in the meta-analysis. 85.5% of the dentists and oral health practitioners had a high level of awareness about virus transmission modes (95% confidence interval [CI]: 78.6%-92.4%; P < 0.001). 80.7% of the oral health practitioners gave right answers to the questions related to virus transmission modes (95% CI: 69.9%-91.4%; P < 0.001), and 79.9% of the dentists had a positive attitude about virus transmission modes (95% CI: 66.4%-93.4%; P < 0.001). CONCLUSION: This meta-analysis shows that the level of dentists and oral health practitioners' knowledge, awareness, and attitude was relatively high about the respiratory contagious diseases as well as COVID-19. The present results can shed further light for policymakers to support the best evidence medical education for all health-care workers the same as oral health practitioners. Preventing the dissemination of misinformation along with preparing comprehensive guidelines can be considered by the oral health policymakers, particularly in the more infected regions.
