Infection control practices in dental healthcare settings for the corona virus disease 2019 (COVID-19) pandemic

The constant presence of bioaerosols in dental procedures represents a challenge for dental healthcare services during the Coronavirus Disease 2019 pandemic (COVID-19). The main transmission pathway of its etiological agent-severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2)-occurs through droplets. Thus, when considering that saliva is a reservoir for this virus, dentistry is one of the activities with greater exposure to risk, with the need to establish strict safety protocols. This study is based on relevant guidelines and research andreviewed the scientific literature in order to present infection control practices to prevent SARS-CoV-2 contamination in dental healthcare settings.
