The severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) pandemic effects daily dental work. Therefore, infection control measures are necessary to prevent infection of dental personnel during dental treatments. The use of a preprocedural mouth rinse with chlorhexidine (CHX), cetylpyridinium chloride (CPC), or hydrogen peroxide (H(2)O(2)) solution for 30-60 s may reduce the viral load and may protect the personnel in a dental practice. In the present study the virucidal effect of the mouth rinsing solutions ViruProX((R)) with 0.05% CPC and 1.5% H(2)O(2) and BacterX((R)) pro containing 0.1% CHX, 0.05% CPC, and 0.005% sodium fluoride (F(-)) was investigated in vitro. The mouth rinsing solutions successfully inactivated infectious SARS-CoV-2 particles, the causative agent of coronavirus disease 2019 (COVID-19), within 30 s. To determine the effective components, CHX, CPC, H(2)O(2), and a combination of CHX and CPC, were tested against SARS-CoV-2 in addition. While a combination of CPC and CHX as well as CPC alone led to a significant reduction of infectious viral particles, H(2)O(2) and CHX alone had no virucidal effect against SARS-CoV-2. It can be assumed that preprocedural rinsing of the mouth with ViruProX((R)) or BacterX((R)) pro will reduce the viral load in the oral cavity and could thus lower the transmission of SARS-CoV-2 in dental practice.
