Aerosols in Dentistry: A Review

This review examines the risk of infection transmission in dental settings through aerosols, particularly in light of the COVID-19 pandemic. Dental procedures, particularly those involving high-speed instruments, produce aerosols containing saliva, blood, and microbes. These aerosols pose a significant risk of transmission, especially in close contact situations. Measures such as high-volume evacuation, barrier protection (masks, gloves, eye protection), and preprocedural rinses with antiseptic mouthwash can help reduce aerosol contamination. However, the effectiveness of these measures varies, and more research is needed to fully understand and mitigate the risk. The review also discusses the legal and regulatory considerations surrounding aerosol contamination in dental practices. Ultimately, adherence to recommended protocols from organizations like the CDC and ADA is crucial for minimizing aerosol-related infection transmission in dental settings, particularly in the context of the ongoing COVID-19 pandemic.
