About this study
Official title: Clinical Effect of Lactobacillus Reuteri in Treatment of Gingivitis. Randomized Clinical Trials
The aim of this randomized placebo- controlled clinical trials is to evaluate the effects of Lactobacillus reuteri containing probiotic lozenges as an adjunct to scaling and root planning (SRP). Material and methods: Thirty six gingivitis patients will be recruited and monitored clinically at baseline, 3 and 6 month after therapy. All patients will receive scaling and periodontal treatment and randomly will be assigned over an experimental (SRP + probiotic, N=18) or control (SRP+ placebo, n=18) group. The lozenges will be used once per day during 3 month.
Read the detailed description
Gingivitis is the most prevalent worldwide periodontal disease, is characterized by inflammation of the tissues surrounding the tooth without causing periodontal attachment loss. Preventive and / or therapeutic measures to facilitate or improve their control are therefore very important, much more if you consider that gingivitis and periodontitis are considered part of an ongoing inflammatory process. Treatment of gingivitis, like that of all periodontal diseases has been based on the implementation of control measures personal and professional plaque. Notwithstanding the foregoing, it has been reported that although mechanical therapy achieved significantly decrease the periodontopathogens, this may be only temporary since bacteria can recolonize the treated niches in the oral cavity. In this context, it has emerged as a new treatment strategy complementary use of probiotics such as Lactobacillus reuteri, which possess anti-bacterial and anti-inflammatory properties. Generally speaking, probiotics would promote health by competitive exclusion of some or positive pathogenic bacteria. Objective: To evaluate the effect of the administration of Lactobacillus reuteri as an adjunct to conventional periodontal therapy in adolescent and young adult patients with gingivitis. Methodology: A randomized double-blind clinical trial to evaluate the effect of probiotic lozenges Lactobacillus rhamnosus as an adjunct to conventional periodontal treatment of patients with gingivitis will be performed. Expected Results: Statistically significant decrease in bleeding and gingival index in the experimental group compared with the control.

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 6 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 21 Jun 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?
Contact Joel E Bravo Bown, Proffesor (+5694540294, jbravo@odontologia.uchile.cl), or a site near the patient. AzTrials does not enrol participants or take referrals.
What does the primary outcome measure?
Differences between groups for bleeding on probing changes (time frame: baseline, 1, 3 month). 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 21 Jun 2016.
