Healthy Clinical Trial
Official title:
Clinical Efficacy of Single-Use of Peroxyl Mouthwash for Reducing Bacteria in Saliva and Bioaerosol Contamination Phase 2
To evaluate the antibacterial efficacy of a commercial mouthwash containing 1.5% hydrogen peroxide in reducing the levels of bacteria in bioaerosols generated by dental prophylaxis.
Following a washout period, subjects will return to the clinical site. A baseline microbial sample will be collected from the operatory's atmosphere for 30 min. prior to the study subject appointment by placing blood agar plates on a support board attached to the bracket chair tray. Upon completion of a half-mouth (e.g. right side) dental prophylaxis, each study subject will be instructed to rinse for one minute with 10 ml of one of the two mouthwash solutions (1.5% hydrogen peroxide or 0.0% hydrogen peroxide) and to expectorate all remaining liquid. Next, the dental prophylaxis will be completed on the other side of the mouth. Bioaerosol samples will be collected prior to and following rinsing on blood agar plates placed on a support board at a 50-degree angle to the participant's chest, on the participant's chest, and on the examiner's forehead. Plates will be closed and labeled. The plates will be transferred to the microbiology laboratory for analysis. All subjects will be followed for adverse events throughout the study. ;
