About this study
Official title: Clinical Efficacy of Single-Use of Peroxyl Mouthwash for Reducing Bacteria in Saliva and Bioaerosol Contamination Phase I
To evaluate the anti-bacterial, pre-procedural, clinical efficacy of Peroxyl mouthwash (1.5% hydrogen peroxide) in saliva and the reduction of bioaerosol contamination as compared to a matching placebo mouthwash (0.0% hydrogen peroxide)
Read the detailed description
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.

What is being measured
The primary outcome is the main question the study is designed to answer.

Questions about this trial
What is this clinical trial studying?
A Phase 2 study testing Peroxyl Mouthwash in people with Healthy, run by Colgate Palmolive at 1 site in United States.
The full registered description is in the About this study section and the official record.
Who may be eligible to take part?
The sponsor lists 7 inclusion and 14 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.
Is this clinical trial currently recruiting?
The record says: finished, as of the sponsor's last update on 20 Jan 2021. Status can change between updates, so confirm with the study contact before making plans.
Where is the study taking place?
The record lists 1 site in United States. Whether a site is taking part right now should be confirmed with that site. See every site.
What are the possible benefits and risks?
They depend on the study and the treatment, and no study can promise a benefit. Some participants in this study may receive a placebo. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.
What does this phase mean?
Phase 2 studies give the treatment to a larger group to see whether it has the intended effect and to keep checking safety.
Not every study follows the same path, and some studies (observational studies, device studies) have no phase.
Are results available for this study?
The study is completed, but results are not available in the source record. That does not mean the treatment did or did not work.
How can a doctor refer a patient or contact the research team?
The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.
What does the primary outcome measure?
Change in the Colony Forming Unit of total bacteria in saliva and in bioaerosol (time frame: baseline, 30 minutes & 60 minutes). It is what the study was designed to measure, not a finding.
Where can I read the original study information?
Does a listing mean the treatment is approved or proven to work?
No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.
How often is this information updated?
AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 20 Jan 2021; AzTrials last refreshed its copy on 8 Nov 2026.
