Impact of Non-surgical Periodontal Therapy on Oral and Gut Microbiome

May 25, 2021 updated by: Renato Casarin, University of Campinas, Brazil

Impact of Non-surgical Periodontal Therapy With or Without Antibiotics on Oral and Gut Microbiome in Patients With Stage III/IV and Grade C Periodontitis

Periodontitis is an inflammatory disease characterized by a dysbiotic microbiome which can lead to bone destruction and tooth loss. Several studies had been reported the association to periodontal disease with systemic conditions and this relation suggests and axis that links oral and gut microbiome. In order to clarify the impact of periodontal condition on gut microbiome, we aim to evaluate the clinical, immunological parameters and the microbiological condition by sequencing of subgingival biofilm and stool samples both before and after non-surgical periodontal treatment with and without antibiotics as adjunct.

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.

Study Type

Study Type

Describes the nature of a clinical study. Study types include interventional studies (also called clinical trials), observational studies (including patient registries), and expanded access.
Interventional

Enrollment (Anticipated)

Enrollment

The number of participants in a clinical study. The "anticipated" enrollment is the target number of participants that the researchers need for the study.

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

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
Change in the oral-gut axis microbiome at 3 months
Time Frame: Baseline and 90 days
Concentration of bacteria in the subgingival biofilm and stool samples
Baseline and 90 days

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
Change of biofilm gene expression on oral microbiome at 3 months
Time Frame: Baseline and 90 days
RNA-seq of 3 samples FMUD+AM group and validation by quantitative polymerase chain reaction
Baseline and 90 days
Change of the baseline inflammatory markers levels in gingival crevicular fluid (pg/uL) and stool samples
Time Frame: Baseline and 90 days
Concentration of cytokines and biomarkers in gingival crevicular fluid and in stool samples
Baseline and 90 days
Change of the baseline relative clinical attachment level at 3 months
Time Frame: Baseline, 30 days and 90 days
Distance from the bottom of the pocket to the stent margin.
Baseline, 30 days and 90 days
