About this study

The goal of this clinical study was to evaluate whether non-surgical treatment for severe periodontitis (gum disease) could improve body-wide inflammation and blood fat levels in young adults with severe periodontitis. The main questions it aimed to answer were:

Did non-surgical periodontal treatment improve gum health in young adults with severe periodontitis?

Did non-surgical periodontal treatment change body-wide inflammation and blood fat levels after treatment?

Researchers compared participants with severe periodontitis to healthy participants without periodontitis.

Participants with severe periodontitis:

  • Received oral hygiene instructions, deep cleaning below the gumline, root surface cleaning, and removal of teeth that could not be saved
  • Had full-mouth gum examinations
  • Provided blood samples at the start of the study and again at 2 and 6 months after treatment

Healthy participants:

  • Had gum examinations
  • Provided blood samples for comparison at the start of the study

What participants receive

What participants receive. In a randomised study each person is assigned to one group by chance.

  • Non-surgical periodontal treatmentProcedure or surgery

    Non-surgical periodontal treatment consisted of oral hygiene instruction, subgingival scaling, root planing, and extraction of unsalvageable teeth under local anesthesia. Treatment was completed within 1 week. Clinical periodontal measurements and blood samples were obtained at baseline and repeated at 2 and 6 months after completion of treatment.

Study groups in NCT07526883
Study groupRoleWhat they receive
Healthy GroupNo interventionThe healthy control arm included systemically and periodontally healthy young adults with no periodontal or systemic disease who met the same exclusion criteria as the periodontitis group. Participants did not receive periodontal treatment. They underwent baseline full-mouth periodontal examination and blood sampling to provide healthy reference values.
Periodontitis GroupActive comparatorThe periodontitis arm included systemically healthy young adults with severe periodontitis. Participants underwent baseline full-mouth periodontal examination and blood sampling, received non-surgical periodontal treatment, and were re-evaluated at 2 and 6 months after treatment.
Receives: Procedure: Non-surgical periodontal treatment

Questions about this trial

What is this clinical trial studying?

A study testing Non-surgical periodontal treatment in people with Periodontitis, Aggressive, run by Istanbul University at 1 site in Turkey (Türkiye).

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 7 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 13 Apr 2026. 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 Turkey (Türkiye). 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?

The change in serum high-sensitivity C-reactive protein (hs-CRP) concentration after periodontal treatment (time frame: 6 months). The study lists 15 primary outcomes in all. 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 13 Apr 2026.
