About this study

Official title: Clinical Effect of Probiotic Use Bifidobacterium Animalis Subsp. Lactis as Adjunctive Therapy in Non-surgical Treatment of Periimplant Mucositis: a Randomized Controlled Trial

Peri-implant disease is an inflammatory process of bacterial etiology that can affect the tissues around the implants and can be classified as peri-implant mucositis or peri-implantitis. The confirmation of the action of probiotics against microorganisms that cause peri-implant diseases can represent a great advance in the treatment of these diseases that affect a large part of the population, and may even reduce or prevent the use of antibiotics, reducing the risk of implant loss and, consequently, greater damage to the oral and systemic health of individuals. The purpose of this study was to evaluate the action of probiotics on the peri-implant health of total edentulous patients using Branemark protocol prosthetic rehabilitations. For this, 38 patients were selected, without systemic alterations and non-smokers. Clinical monitoring was performed at baseline (pre-intervention period) as well as at 12 and 24 weeks after study initiation. The following parameters were evaluated: modified gingival index (MGI), modified plaque index (MPI), probing depth (PD) and probing bleeding (PB). Data were subjected to statistical analysis at a significance level of 5%. There was an increase in sites with IGM 0 in the test group at 12 and 24 weeks. The test group presented more sites with IGM 0 than the control. IPM 0 sites increased in the control group at 12 and 24 weeks in the control group. PD decreases in a test and control group. Finally, the test group had lower PB rates. Thus, the probiotic used demonstrated ability to contribute to the improvement of peri-implant health of the patients analyzed.

Read the detailed description

Clinical monitoring. MGI (0: no bleeding when a periodontal tube is passed along the mucosal margin adjacent to the implant; 1: visible isolated bleeding points; 2: blood forms a confluent red line at the mucosal margin and 3: profuse bleeding) and the MPI (0: no plaque; 1: plaque recognized only by probing through the smooth marginal surface of the implant; 2: plaque can be seen with the naked eye; 3: abundance of alba matter). PD was determined using a soft plastic periodontal probe for torque-controlled implants at 0.15 N / cm. Three buccal and three lingual reference points for each implant were used to calculate the mean probing depth in millimeters for each implant. PB was dichotomously evaluated: the presence of bleeding was considered positive when it occurred within 20 seconds after insertion of the probe to measure PD. The height of the keratinized mucosa present around each implant was also measured.

All clinical parameters described above were recorded at baseline (pre-intervention period) as well as at 12 and 24 weeks after study initiation.

Treatment of peri-implant mucositis and maintenance care. Prior to the beginning of the intervention, all patients received oral hygiene instruction. Mechanical debridements were performed with titanium curves and polishing using a rubber bowl and polishing paste. In the Test Group the treatment session was completed by a professional topical application around the carboxymethylcellulose gel implants containing 109 colony (CFU) forming units of B. lactis HN019. The gel was applied sub and supragingivally. The patients then received commercial capsules containing the same bacteria and were instructed to dissolve the capsule contents in 20 mL of water and rinse for 30 to 60 seconds, followed by swallowing twice a day for 12 weeks. The control group received the same oral hygiene instructions, mechanical debridement and was treated with gel and placebo tablets. At 3 months postoperatively, the same local mechanical and chemical treatment was repeated for the Test and Control groups.

Questions about this trial

What is this clinical trial studying?

A Phase 3 study testing Mechanical debridements and Bifidobacterium animalis subsp. lactis in people with Mucositis Oral, run by University of Sao Paulo at 1 site in Brazil.

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 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 5 Dec 2019. 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 Brazil. 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 3 studies compare the treatment with the current standard treatment or a placebo in a large group, to confirm how well it works and watch for side effects.

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?

Bleeding the probing. (time frame: Baseline.). The study lists 3 primary outcomes in all. 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 NCT04187222, which also lists 4 linked publications.

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 5 Dec 2019.
