“…In the present study, the limited supply of antigen test kits during the fourth wave of the COVID-19 pandemic in Thailand led our team to take an efficacious strategy and practical approach to using such limited kits in this study. Those patients who are set up to receive aerosol-generating dental treatment have a higher chance of spreading viral particles in the dental treatment environment ( 21 , 22 ). Thus, the screening for SARS-CoV-2 infection was focused on these groups, despite the fact that all patients possess the risk of infection.…”

Potential aerosols containing severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) viral particles can be generated during dental treatment. Hence, patient triage is essential to prevent the spread of SARS-CoV-2 in dental clinical settings. The present study described the use of rapid antigen tests for SARS-CoV-2 screening prior to dental treatment in an academic dental clinical setting in Thailand during the pandemic. The opinions of dental personnel toward the use of rapid antigen test screening prior to dental treatment were also assessed. From August 25 to October 3, 2021, dental patients who were expected to receive aerosols generating dental procedures were requested to screen for SARS-CoV-2 using a rapid antigen test before their treatment. A total of 7,618 cases completed the screening process. The average was 212 cases per day. Only five patients (0.07%) were positive for SARS-CoV-2 in the rapid antigen screening tests. All positive cases exhibited mild symptoms. For the questionnaire study, experienced dental personnel frequently and consistently agreed with the use of the rapid antigen test for SARS-CoV-2 screening, which made them feel safer during their patient treatment. However, implementing rapid antigen tests for SARS-CoV-2 may increase the total time spent on a dental appointment. In conclusion, a rapid antigen test could detect the infected individual prior to dental treatment. However, the specificity of rapid antigen tests for SARS-CoV-2 must be taken into account for consideration as a screening process before dental treatment. The enhanced infection control protocols in dental treatment must be consistently implemented.

“…In this study, the bioaerosol was regarded as a sphere with a density of 1000 kg/m 3 [ 44 ]. An initial velocity of 0.68 m/s was selected [ 45 , 46 ]. The direction of the bioaerosol release was perpendicular to the back of the treatment chair.…”

“…3 During this time, several investigations were performed to evaluate the pattern of aerosol transmission and the impact of mitigation devices. 4 As oral health educators complied with these guidelines, they also began to strategize, create, investigate, and transform clinical aspects of oral health education. 5 The combination of local executive orders and agency guidelines resulted in institutions modifying clinical space and clinical flow to ensure the safety of practitioners and students/residents.…”

“…Ou et al., evaluated the spatter from ultrasonic scaling and revealed the use of high‐volume evacuation and extraoral local extractors considerably reduced aerosols. 4 There is a continuous need for educators and researchers to investigate how patient care can be safely performed in large open bay clinics. What is the optimum air exchange for our clinics?…”
