“…Our results are concordant with those of previous reports in that the combination of IOS and EOS reduces aerosols more than that of IOS alone [37,38]. IOS spreads aerosols faster during high-speed handpiece preparation and powder jet cleaning than in saliva drainage tubes [39].…”

Some infectious diseases, including COVID-19, are primarily transmitted via droplets and aerosols. Droplets are larger in particle size and settle to the ground faster due to gravity (3-6 feet) [3]. Aerosols are smaller in particle size and remain airborne for relatively long durations. The aerosol particle size has not been conclusively defined and reportedly ranges from less than 5 µm to 50 µm [4]. Larger particles can carry a higher quantity of viral load and are more likely to be deposited in the upper airways. In contrast, particles smaller than 10

“…No consensus has been attained regarding the optimal EOS location. In previous reports, the EOS suction hood was set primarily 10-40 cm from the patient's mouth [37][38][39][40][41][42][43]. In this study, the EOS was set 10 cm above the patient's mouth, which might have resulted in a significant effect.…”

“…Nevertheless, the application and efficacy of EOS in the dental environment is still debated in the literature and questions still remain open about their appropriate use. Therefore, further research in this area is essential to work towards a safer dental practice [ 23 – 25 ].…”

Background The SARS-CoV-2 pandemic has raised awareness of the importance of air quality. This pilot study arose from the need to reduce the concentration of particulate matter in the dental office during orthodontic procedures. To evaluate the efficacy of using an air purifier during orthodontic care in the dental office to reduce the concentration of ambient particulate matter. Results Significant reductions in particle numbers were obtained for all particle sizes except the largest particles counted (10 μm) through use of the air filter. A marked association between higher humidity levels and higher particle counts was also observed. Conclusions Using an air purifier during dental care achieves a significant reduction in the concentration of ambient particles in the dental office. There is a correlation between higher relative humidity and higher particle concentration. The probability of obtaining a maximum particulate concentration level of 0.3 and 0.5 μm is 1000 times lower when using an air purifier.

“…It can help reduce the risk of COVID-19 spread during dental procedures, especially near the patient's | VOL 13, NO.2, Juni 2024; 189-199 head, where most aerosols are generated [9]. Apart from that, extra oral suction is used simultaneously with HVS, and a saliva ejector operated by an assistant [10]. The specific composition of extra oral suction units may vary depending on the manufacturer and model.…”

The spread of COVID-19 through aerosols and droplets occurs during dental treatment. Dentists use high-volume suction (HVS) and saliva ejectors to suction saliva, blood, and water from the oral cavity. Since the pandemic, prototyping, production, and use of extraoral suction (EOS) have increased. EOS comprises HEPA (High-Efficiency Particulate Air), plasma ions, and ultraviolet (UV) filters. This study was used to see the effectiveness of the use of EOS through a comparison of physical and acceptability tests on the use of EOS at UGM Prof. Sodeomo Dental Hospital using three EOS brands, Coxo™, Eighteeth™ Vacstation, and Eostra™. Physical Test is used to assess the ability of a tool when used—Acceptability Test to assess user acceptance of EOS based on usage experience. The study was conducted at the UGM Prof. Soedomo Hospital (Professional Education Clinic, Resident Education Clinic, General Service Unit, and Specialistic Service Unit) in 2021 with 90 respondents who were EOS users. The EOS with the most incredible suction power, noise figure, and electrical power was Eostra™, while based on user experience, the EOS that was more accepted and more comfortable for users to use was Coxo™. EOS reduces aerosol exposure during dental treatment, and based on this study, EOS that had good capacity was not necessarily comfortable to use by users; this was because each brand had advantages and disadvantages, so the selection of EOS was adjusted to the capacity of the operator and the practice site.
