Use of Probiotics in Oral Health of Patients With Dental Implants

October 27, 2013 updated by: Antonio Juan Flichy Fernández, University of Valencia

THE EFFECT OF ORALLY ADMINISTERED PROBIOTIC LACTOBACILLUS REUTERI-CONTAINING TABLETS IN PERI-IMPLANT MUCOSITIS: A RANDOMIZED CLINICAL TRIAL

The aim of this study was evaluate the effects of the oral probiotic Lactobacillus reuteri Prodentis upon the peri-implant health of edentulous patients with dental implants and peri-implant mucositis, establishing comparisons versus implants without peri-implant disease. The hypothesis of the study is that using these probiotics are going to improve the periimplant health.

Conditions

Conditions

The disease, disorder, syndrome, illness, or injury that is being studied. On ClinicalTrials.gov, conditions may also include other health-related issues, such as lifespan, quality of life, and health risks.

Intervention / Treatment

Intervention / Treatment

A process or action that is the focus of a clinical study. Interventions include drugs, medical devices, procedures, vaccines, and other products that are either investigational or already available. Interventions can also include noninvasive approaches, such as education or modifying diet and exercise.

Detailed Description

A double-blind, placebo-controlled, prospective cross-over study was made. All the patients were edentulous and were divided into two groups: A) with no peri-implant disease; B) with peri-implant mucositis affecting one or more implants. Patients with peri-implantitis were excluded. All patients in both groups initially received the oral probiotic Lactobacillus reuteri Prodentis, followed by placebo. Only the supervisor of the study knew this information; clinical examiner and patients were blind. Were studied: crevicular fluid volume, modified plaque index, probing depth, modified gingival index, and concentrations of interleukin 1β, interleukin 6 and interleukin 8, and Bacterial load.

Phase

Phase

The stage of a clinical trial studying a drug or biological product, based on definitions developed by the U.S. Food and Drug Administration (FDA). The phase is based on the study's objective, the number of participants, and other characteristics. There are five phases: Early Phase 1 (formerly listed as Phase 0), Phase 1, Phase 2, Phase 3, and Phase 4. Not Applicable is used to describe trials without FDA-defined phases, including trials of devices or behavioral interventions.

Participation Criteria

Researchers look for people who fit a certain description, called eligibility criteria. Some examples of these criteria are a person's general health condition or prior treatments.

Eligibility Criteria

Eligibility Criteria

The key requirements that people who want to participate in a clinical study must meet or the characteristics they must have. Eligibility criteria consist of both inclusion criteria (which are required for a person to participate in the study) and exclusion criteria (which prevent a person from participating). Types of eligibility criteria include whether a study accepts healthy volunteers, has age or age group requirements, or is limited by sex.

Ages Eligible for Study

50 years to 80 years (Adult, Older Adult)

Accepts Healthy Volunteers

Yes

Genders Eligible for Study

All

Description

Inclusion Criteria:

  • Totally edentulous patients subjected to dental implant rehabilitation in one or both arches
  • Prosthetic restoration in function for at least 24 months
  • Healthy individuals without known disease

Exclusion Criteria:

  • Patients receiving any kind of local or systemic decontamination treatment of the oral cavity (e.g., antibiotics or rinses) in the last 3 months, or periodontal treatment in the last 6 months
  • Uncontrolled periodontal disease
  • Patients with immune deficiencies, diabetes, rheumatoid disease, head and neck radiotherapy, bisphosphonate treatment, chemotherapy or anticoagulation
  • Patients with dental implants presenting intraoral exposure of the rough portion of any implant
  • Smokers

  • Failure to provide informed consent to participation the study
  • Patients presenting at least one implant with peri-implantitis

Arms and Interventions

Participant Group / Arm

Participant Group / Arm

A group or subgroup of participants in a clinical trial that receives a specific intervention/treatment, or no intervention, according to the trial's protocol.
Intervention / Treatment

Intervention / Treatment

A process or action that is the focus of a clinical study. Interventions include drugs, medical devices, procedures, vaccines, and other products that are either investigational or already available. Interventions can also include noninvasive approaches, such as education or modifying diet and exercise.
Experimental: Probiotic Lactobacillus reuteri Vs Placebo
patients with full arch with dental implant received a tablet of Lactobacillus reuteri every day during 28 days, and after a wash-up, the same patients receive a tablet of placebo every day during 28 days
Dietary supplement: Placebo tablets
Other Names:
  • Placebo tablets with same visually aspect, flavour and texture than the probiotic but without probiotic strains
Dietary supplement: Probiotic tablets of Lactobacillus reuteri
Other Names:
  • strains of Lactobacillus reuteri ATCC PTA 5289 - 100 million

What is the study measuring?

Primary Outcome Measures

Primary Outcome Measures

In a clinical study's protocol, the planned outcome measure that is the most important for evaluating the effect of an intervention/treatment. Most clinical studies have one primary outcome measure, but some have more than one.
Outcome Measure
Measure Description
Time Frame
Evidence in reduction of plaque index
Time Frame: 28 days using one probiotic tablet/day
The Mombelli clasification was used to evaluate the reduction of bacterial plaque. 0: No bacterial plaque; 1: presence of bacterial plaque but not visually; 2: 1/3 part of the implant with bacterial plaque; 3: 2/3 parts or more of the implant with bacterial plaque
28 days using one probiotic tablet/day

Secondary Outcome Measures

Secondary Outcome Measures

In a clinical study's protocol, a planned outcome measure that is not as important as the primary outcome measure for evaluating the effect of an intervention but is still of interest. Most clinical studies have more than one secondary outcome measure.
Outcome Measure
Measure Description
Time Frame
Evidence in reduction of bleeding around implants
Time Frame: 28 days using probiotic tablet/day
The Mombelli classification was used to evaluate the reduction of bleeding around implants: 0: no bleeding; 1: a point of bleeding; 2)a line of bleeding; 3: much bleeding
28 days using probiotic tablet/day
Evidence in reduction of probing depth
Time Frame: 28 days using one probiotic tablet/day
Was measured in reduction of millimeters of the depth of the implant with a millimeter probe.
28 days using one probiotic tablet/day
Evidence in reduction Interleukin 1β concentration

Evidence in reduction Interleukin 8 concentration
Time Frame: 28 days using one probiotic tablet/day
concentration measured in picograms/milliliter (pg/ml)
28 days using one probiotic tablet/day

Other Outcome Measures

Other Outcome Measures

For clinical trials, a planned measurement described in the protocol that is used to determine the effect of an intervention/treatment on participants. For observational studies, a measurement or observation that is used to describe patterns of diseases or traits, or associations with exposures, risk factors, or treatment. Types of outcome measures include primary outcome measure and secondary outcome measure.
