This protocol, with small variations, has been accepted by the main professional dental associations worldwide, such as the American Dental Association (ADA, 2020). Based on this argument, it has been suggested that the measures for controlling cross-infection during dental practice should include a preprocedural mouth rinse containing oxidative agents such as 1% hydrogen peroxide and 0.2% povidone iodine (PVP-I) (Peng et al., 2020). As a result, the dental clinic is considered an environment of risk for dental healthcare personnel and their patients, particularly due to the potential transmission of the virus through droplets and aerosols (Peng et al., 2020).
The detection of SARS-CoV-2 in the saliva of patients with coronavirus disease (COVID-19) has made this biological fluid relevant in terms of the diagnosis and transmission of the infection (Azzi, Carcano, Gianfagna, et al., 2020 To, Tsang, Yip, et al., 2020).
