The Impact of the COVID-۱۹ Pandemic on Infection Control Protocols in Dentistry: A Questionnaire-based Survey in Iran

Aim: The COVID-۱۹ pandemic has presented significant challenges for healthcare professionals, particularly in the field of dentistry. This study aimed to evaluate the changes in infection control measures in dentistry before and during the pandemic among Iranian dentists.Methods: An analytical cross-sectional study was conducted from June to December ۲۰۲۰, and included dental healthcare professionals (DHCPs) practicing dentistry in Iran. Participants completed a web-based survey that included demographic profiles, practice-related details, and information on implemented infection control measures. Data were subjected to statistical analysis using the software SPSS v. ۲۶, and a P-value<۰.۰۵ was considered statistically significant. Results: A total of ۳۰۳ dentists, ۲۰۰ (۶۶%) of whom practiced specialized dentistry and ۱۰۳ (۳۴%) were general dentists, responded to the questionnaire. The majority of participating dentists (۸۵.۵%) were aware of the importance of patient screening for COVID-۱۹ symptoms. There was a statistically significant rise in adherence to hand hygiene practices. The utilization of personal protective equipment (PPE), such as gloves, masks, and face shields also exhibited significant increases amid the pandemic. Dentists shifted from using surgical masks to N۹۵ respirators (p=۰.۰۵) and white coats to disposable gowns (p<۰.۰۰۱). We noted a significantly greater tendency towards adopting air ventilation systems, surface disinfection and prescribing preprocedural mouth rinses among DHCPs.Conclusion: The study findings indicate increased compliance with infection control protocols during the COVID-۱۹ pandemic among Iranian DHCPs and highlight the modifications made to infection control measures in dentistry.
