Estimating Salivary Carriage of Severe Acute Respiratory Syndrome Coronavirus 2 in Nonsymptomatic People and Efficacy of Mouthrinse in Reducing Viral Load. Authors of this article undertook two studies to understand levels of SARS-CoV-2 in the saliva of potential dental patients and to test how well mouthrinses worked to lower the virus levels. These studies revealed two key findings:

1. Saliva caries a high rate of virus in nonsymptomatic patients, although low enough that the likelihood of transmission is also low.

2. A mouthrinse of 1% hydrogen peroxide, 0.12% chlorhexidine, or 0.5% povidone-iodine for 60 seconds works well to reduce virus levels in saliva for up to 45 minutes.
