Abstract:	The investigation of the real risk of contagion by the SARS-CoV-2 virus in dental professionals deserves attention due to the direct and indirect contact with droplets, secretions from the upper airways and blood during patient care. The objective of this cross-sectional study was to determine the prevalence of antibodies against the SARSCoV-2 virus in dental professionals, such as Dental Surgeons (CDs), Oral Health Technicians (TSBs) and Oral Health Assistants (ASBs) and their factors associated, as well as the biosecurity measures and conditions and the opinion on the impact of the pandemic on the work process of professionals. A stratified draw was carried out for the CDs registered at the Regional Council of Dentistry of the Federal District, according to the 33 administrative regions of the Federal District (Brazil); and for ASBs/TSBs, 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 DCs and 193 ASBs/TSBs were evaluated. The chi-square test evaluated the difference between the prevalence of infection according to the exposure variables. For continuous variables, the Mann Whitney and Wilcoxon tests were used. Odds ratios (OR) and 95% confidence intervals (95% CI) were calculated using a logistic regression model. The seroprevalence of infection among DCs was 19.1% (n=62), and among ASBs/TSBs it was 23.3% (n=45). There was a significant association between seropositivity and confirmed prior diagnosis of COVID19 (p <0.0005), diagnosis of COVID-19 at home (p <0.0005) in DCs and ASBs/TSBs; loss of taste or smell (p=0.01), having treated patients with fever (p=0.03) in DCs. DCs and ASBs/TSBs with a confirmed prior 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. DCs with households with a confirmed diagnosis of COVID-19 were 2.46 times more likely (95% CI 1.13 - 5.34, p = 0.02) to have positive serological results. DCs 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 show positive serology. DCs who treated patients with fever were 2.99 times more likely (95% CI 1.03 - 8.70, p = 0.04) to have negative serology. Most professionals reported a reduction in hours worked. The main routine changes in clinical practice were asking the patient, before the appointment, about symptoms of COVID-19 and adjustments in the organization of the waiting room. The use of Personal Protective Equipment was highly prevalent, particularly respiratory masks. The study's findings apply to the 2020 epidemiological scenario, prior to the development of vaccines and the emergence of the SARS-CoV-2 Delta variant.
