| Summary: | Abstract Introduction In light of the COVID-19 pandemic, biosafety protocols in dentistry have been intensified due to the high risk of aerosol contamination. This study aims to evaluate the spatial distribution of aerosols and the effectiveness of Prime Protector (protective dome) in simulated dental procedures, aiming to enhance protective measures in dental offices. Objective This study evaluated the spatial distribution of aerosols and the effectiveness of Prime Protector (protective dome) during aerosol-generating dental procedures. Material and method A simulation unit equipped with a dental simulator and working position was used. Cotton cellulose filter paper discs (12.5 cm in diameter) and adhesive tape were placed at distances of 0.5, 1, 1.5 and 2 meters in two different directions corresponding to the 12 and 2 o'clock positions on the clock. The procedures included scaling and dental prophylaxis in the upper incision, performed with or without a dome. Result At the end of the procedure, the filter papers were collected and the deposited droplets were counted. Significant differences were identified in the procedures applied (p=0.000), in the distances (p=0.000) and in the time of collection (p=0.000). Greater distance, shorter time after the procedure and the use of the dome reduced the aerosol droplets. Conclusion Prime Protector neutralizes the spatial propagation of aerosols during simulated dental procedures and increases biosafety, providing greater protection to dental office staff. |
