About this study

Official title: Efficacy of Oral Probiotic and Antibiotic Administration in Clinical, Immunological and Microbiological Parameters of Patients With Chronic Periodontitis Treated With Non Surgical Periodontal Treatment

The aim of this randomized placebo- controlled clinical trial is to evaluate the effects of Lactobacillus rhamnosus SP1- containing probiotic tablets and azithromycin tablets as an adjunct to scaling and root planning (SRP).

Material and methods: Fifty-four chronic periodontitis patients will be recruited and monitored clinically, immunologically and microbiologically at baseline, 3, 6, 9 and 12 months after therapy. All patients will receive scaling and root planning and randomly will be assigned over an probiotic experimental (SRP + probiotic, n=18), antibiotic experimental (SRP + Azithromycin, n=18) or control (SRP + placebo, n=18) group. Probiotic will be used once per day during 3 months. Antibiotic will be used once per day during 5 days.

Secondary outcomes (5)
  1. Differences between groups for probing depth changes

    Measured: baseline, 3, 6, 9 and 12 month

  2. Differences between groups for bleeding on probing changes

    Measured: baseline, 3, 6, 9 and 12 month

  3. Differences between groups for plaque index changes

    Measured: baseline, 3, 6, 9 and 12 month

  4. Differences between groups for levels of Interleukin (IL)-17, IL-8, beta-defensing 3 changes in gingival crevicular fluid

    Measured: baseline, 3, 6, 9 and 12 month

  5. Differences between groups for levels of periodontal pathogens changes

    Measured: baseline, 3, 6, 9 and 12 month

Questions about this trial

What is this clinical trial studying?

A Phase 2 study testing Lactobacillus rhamnosus SP1, Azithromycin and Talc powder in people with Chronic Periodontitis, run by University of Chile at 1 site in Chile.

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 4 inclusion and 3 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 Sep 2016. 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 Chile. 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?

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?

Differences of at least 1mm between groups for clinical attachment level changes (time frame: baseline, 3, 6, 9 and 12 month). 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 NCT02839408, 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 Sep 2016.
