Hand washing before and after a dental appointment with a patient (97.7%) followed by use of barriers to protect mucosa (97.2%) were the more frequently recognized measures to prevent COVID-19 spread in the dental office. As for the perception of COVID-19, 73.2% of the dental students perceive the disease as severe, while only 11.1% of them think that COVID-19 is severe only for people presenting risk factors.

In summary, the dental students demonstrated an acceptable general knowledge about COVID-19, but dental schools will need to address gaps in knowledge and control measures and perceptions to ensure a safer return to practical activities.
