About this study
The present study is a double-blinded randomized clinical trial with a duration of 28 days.
Read the detailed description
The present study is a double-blinded randomized clinical trial with a duration of 28 days.
80 orally and systemically healthy participant will be allocated in the test (probiotic) and the control (placebo) group at baseline.
The intervention is sugar stress, which will be applied at baseline and continue through day 14, followed by 14 days without sugar stress.
Clinical measurements and sampling will be performed at baseline, day 14 and day 28
Primary endpoint: Changes in microbial composition.
Secondary endpoints: Changes in clinical and immunological parameters
- Conditions
- Dental Caries, Probiotics, Gingivitis
- Being tested
- Sugar stress
- Medical subject headings
- Dental Caries, Gingivitis
What participants receive
What participants receive. In a randomised study each person is assigned to one group by chance.
Sugar stressBehavioural
Sucrose rinsing for 14 days (8-10 times a day) followed by 14 days without sucrose rinsing
| Study group | Role | What they receive |
|---|---|---|
| Probiotic | Experimental | In this group participants will receive probiotic supplements twice a day (morning and evening) for at period of 28 days (14 days with sugar stress followed by 14 days without sugar stress). Receives: Behavioral: Sugar stress |
| Placebo | Placebo comparator | In this group participants will receive placebo twice a day (morning and evening) for at period of 28 days (14 days with sugar stress followed by 14 days without sugar stress). Receives: Behavioral: Sugar stress |
What is being measured
The primary outcome is the main question the study is designed to answer.
Changes in microbial composition in dental plaque
Changes in alpha and beta diversity of microbial composition
Measured: Baseline vs. Day 14 and Day 28
Secondary outcomes (2)
Changes in clinical parameters
Changes in levels of dental plaque and gingival inflammation
Measured: Baseline vs. Day 14 and Day 28
Changes in salivary levels of inflammatory cytokines
Changes in mean salivary levels of selected inflammatory cytokines
Measured: Baseline vs. Day 14 and Day 28

Questions about this trial
What is this clinical trial studying?
A study testing Sugar stress in people with Dental Caries and Probiotics, run by University of Copenhagen at 1 site in Denmark.
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 1 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: finished, as of the sponsor's last update on 23 Aug 2022. 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 Denmark. 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.
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?
Changes in microbial composition in dental plaque (time frame: Baseline vs. Day 14 and Day 28). 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 23 Aug 2022; AzTrials last refreshed its copy on 7 Nov 2026.
