Clinical Efficacy of Single-Use of Peroxyl Mouthwash for Reducing Bacteria in Saliva and Bioaerosol Contamination

Qualified subjects will be enrolled and randomized to either one of the two study groups, balanced on the basis of their initial gingival index scores. Saliva samples will be collected from participants prior to rinsing with their assigned mouthwash (1.5% hydrogen peroxide or 0.0% hydrogen peroxide) for one minute and then expectorate. Saliva samples will again be collected immediately after, at 30 min, and 60 min after rinsing. All collected saliva samples will be placed in sterile vials, labeled with subject information and transferred to the microbiology laboratory for analysis.
