SUMMARY:

“The investigation of the real risk of contagion by the SARS-CoV-2 virus in dental professionals deserves attention because of specificities during patient care due to direct and indirect contact with droplets, upper airway secretions, and blood. The objective of this cross-sectional study was to determine the prevalence of antibodies against the SARS-CoV-2 virus in dental professionals, such as Dentists (DDS), Dental hygienists (DH), and Dental assistants (DA), and their associated factors. A stratified draw was carried out for the DDS registered at the Regional Council of Dentistry of the Federal District, according to the 33 administrative regions of the Federal District (Brazil); and for DH/DA, a convenience sample was used. The presence of antibodies against the SARS-CoV-2 virus was verified by the Onsite COVID-19 IgG/IgM rapid test, by collecting a drop of blood through a finger puncture. Participants answered a questionnaire about sociodemographic aspects, exposure factors to COVID-19, and professional practice. A total of 324 DDS and 103 DH/DA were evaluated. The seroprevalence of SARS-CoV-2 infection among DDS was 19.1% (n=62), and among DH/DA it was 23.3% (n=45). There was a statistically significant association between seropositivity and confirmed prior diagnosis of COVID-19 (p<0.0005), diagnosis of COVID-19 at home (p<0.0005) in DDS and DH/DA; loss of taste or smell (p=0.01), having treated patients with fever (p=0.03) in DDS. DDS and DH/DA with a confirmed previous diagnosis of COVID-19 had a chance of 29.52 (95% CI 12.74 - 68.40 p <0.0005) and 26.25 (95% CI 10.81 - 70.42, p < 0.0001) times higher to show positive serological results, respectively. DDS and DH/DA with households with a confirmed diagnosis of COVID-19 had a chance of 2.46 (95% CI 1.13 - 5.34, p = 0.02) and 3.43 (95% CI 1.65 - 7.12, p= 0.001) times higher to present positive serological results, respectively. DDS who presented loss of taste or smell in the previous 15 days were 5.24 times more likely (95% CI 1.14 - 24.09, p = 0.03) to present positive serology. DDS who treated patients with fever were 2.99 times more likely (95% CI 1.03 - 8.70, p = 0.04) to have negative serology. The study's findings apply to the epidemiological scenario in 2020, before vaccine development and the emergence of the SARS-CoV-2 Delta variant.”
