About this study

Official title: Short and Long Term Alterations of Subgingival and Salivary Microbiota in Relation to Periodontal Treatment

The purpose of the present investigation is to record and compare bacterial compositions in subgingival plaque samples and saliva samples in subjects receiving periodontal treatment. The hypothesis is that the composition of the salivary microbiota might reflect local bacterial alterations in relation to periodontal treatment.

Read the detailed description

In this study we plan to enroll 35 subjects with manifest periodontitis, which will be treated according to national and international guidelines. Clinical registration and collection of subgingival plaque samples and saliva samples will be performed at baseline and 2, 6 and 12 weeks after treatment.

Study groups in NCT02913248
Study groupRoleWhat they receive
Conventional periodontal treatmentExperimental35 subjects diagnosed with manifest periodontitis, which will all receive standardized treatment according to protocol. In brief, this treatment includes professional tooth cleaning and thorough instruction in self-performed oral hygiene procedures. Clinical registrations and collection of microbiological samples (subgingival and saliva) will performed at baseline and 2, 6 and 12 weeks after treatment.
Receives: Procedure: Conventional periodontal treatment

What is being measured

The primary outcome is the main question the study is designed to answer.

  1. Changes in α-diversity in saliva samples collected .

    Comparison of α-diversity in saliva samples collected before periodontal treatment and 12 weeks after treatment

    Measured: Baseline and 12 weeks

Secondary outcomes (1)
  1. Specis specific changes in saliva samples collected

    Comparison of relative abundance of bacterial species in saliva samples collected before periodontal treatment to samples collected 12 weeks after treatment

    Measured: Baseline and 12 weeks

Questions about this trial

What is this clinical trial studying?

A study testing Conventional periodontal treatment in people with Periodontitis, run by University of Copenhagen at 1 site in Denmark.

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 1 inclusion and 4 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 3 Feb 2017. 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 Denmark. 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. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.

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?

Changes in α-diversity in saliva samples collected . (time frame: Baseline and 12 weeks). 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 NCT02913248, which also lists 2 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 3 Feb 2017.
