Objective:

To evaluate the knowledge of Brazilian dental students about biosafety measures that should be adopted in the clinical setting during the coronavirus disease-2019 (COVID-19) pandemic.

Methods:

A cross-sectional study with 1,050 dental students was conducted. A semi-structured questionnaire was shared with students. Mean knowledge score on biosafety guidelines during the COVID-19 pandemic was the outcome, with a maximum of 8 scores. Explanatory variables included sociodemographic and educational characteristics, aspects related to biosafety education, actions adopted by the dental schools during the pandemic, and sources of biosafety information. Multivariate linear regression analyses were performed.

Results:

Mean knowledge score was 5.19 (1.28). Female students (β=0.346; 95%CI:0.154–0.539), those enrolled in the intermediate (β=0.525; 95%CI:0.167–0.883) or final (β=0.569; 95%CI:0.200–0.937) stage of course, and those who had already received theoretical-practical training in biosafety (β=0.464; 95%CI:0.063–0.866) presented higher mean knowledge scores. Students who did not receive guidance on aerosol control measures before the pandemic (β=-0.324; 95%CI:-0.519–-0.130) had the lowest score.

Conclusion:

Students presented a medium level of knowledge about dental biosafety measures in the COVID-19 pandemic. Sociodemographic characteristics and those related to the institutional profile of the participants, and access to orientation and training in biosafety may influence their knowledge.
