## 4 Discussion  
Healthcare workers are 10 times more likely to contract infectious diseases than other workers. Infectious diseases such as HCV, HAV, HBV, and HIV pose a great risk for healthcare professionals [1]. During the COVID-19 pandemic, healthcare workers constituted 21% of all cases and 9.6% of all fatalities [21]. Since infections are usually transmitted through droplets, dentists use all protective barrier equipment, including protective goggles, masks, gloves, bonnets, face shields, protective outerwear [22]. Particularly during periods like the COVID-19 pandemic, additional protective measures are considered essential. Rubber dams, combined with powerful suction, minimize the likelihood of aerosol or spatter contamination from saliva and blood. Studies indicate that employing a rubber dam can \begin{table}

Upon reviewing the literature, it was observed that bracketing using rubber dam isolation has not been practiced. Aerosols ranging in size from 1 to 5 \(\upmu\)m can remain suspended in the air and spread up to 1-3 m, potentially contaminating surfaces and individuals outside the immediate work area [23; 24]. Previous studies have demonstrated that bacterial and viral particles can be detected in air samples taken 30 min post-procedure, with levels returning to baseline after 2 h [25; 26].
