Minimal intervention dentistry and reduction of aerosol generation of Covid-19: evidence-based recommendations

Transmission of the COVID-19 pandemic was spread by severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2). The oral cavity appears to be a site for SARS-CoV-2 infection and its direct role in viral transmission between dental staff and patients. The aim of this study was evidence-based management for dental caries by Minimal Intervention Dentistry (MID) principles to reduce the generation of aerosols. The MID approaches were divided into 4 levels: non-invasive treatments, micro-invasive treatment, invasive treatment and mixed treatment. The management of caries disease and carious lesions focuses on the control and /or inactivation of the process, such as fluoride-based intervention, pit and fissure sealants, resin infiltration technique, atraumatic restorative treatment and hall technique. Minimal intervention practice protocols for managing carious lesions remove or reduce aerosol generation and are still effective post-COVID-19 care.
