About this study
Official title: Antiplaque Effect of Essential Oils and 0.2% Chlorhexidine on an in Situ Model of Oral Biofilm Growth. A Randomized Clinical Trial
The accumulation and maturation of oral biofilm in the gingival margin is widely recognised to be the primary aetiological factor in the development of chronic gingivitis. Based on this association, the current treatment of gingivitis is focused on biofilm disruption, which will normally include mechanical processes, both professionally and at home. However, for patients, it is not easy to achieve a proper level of plaque control. The efficient plaque control techniques are very time consuming and require a special motivation and skills for their optimum use. It was at this point where mouthwashes become important, due to the fact that they include diverse types of antimicrobial agents to complement the results of mechanical oral hygiene measures.
The essential oils have been presented as a realiable alternative to the "gold Standard" (Chlorhexidine). However, it use has been limited clinically due to their alcohol contain. Some years ago, a new alternative without alcohol has been launched to the market. This formulation has not been already deeply tested specific antiplaque studies in which the structure of the biofilm remained intact.
The aim of this study was to evaluate the in situ antiplaque effect of 2 antimicrobial agents (based on an essential oils formulation with and without alcohol) in the short term with a posterior analysis on "non-destructured" biofilm with Confocal Laser Scanning Microscope combined with fluorescence staining.

Questions about this trial
What is this clinical trial studying?
A Phase 4 study testing Essential oils, Essential oils without alcohol and Sterile water in people with Biofilms and Oils, Essential, run by University of Santiago de Compostela.
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 5 inclusion and 5 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: status not confirmed, as of the sponsor's last update on 27 Oct 2016. Status can change between updates, so confirm with the study contact before making plans.
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 4 studies take place after a treatment is approved, to learn more about its long-term benefits and risks in everyday use.
Not every study follows the same path, and some studies (observational studies, device studies) have no phase.
Are results available for this study?
Results are not available in the source record.
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?
Percentage of bacterial viability (time frame: 96 hours after the volunteer has worn the splints with the disks). It is what the study was designed to measure, not a finding.
Where can I read the original study information?
On the ClinicalTrials.gov record for NCT02946801, which also lists 1 linked publication.
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 27 Oct 2016; AzTrials last refreshed its copy on 7 Nov 2026.
