About this study
Official title: Effects of Minimally Non-surgical Periodontal Treatment Versus Quadrantwise Subgingival Instrumentations on Targeted Metabolomics in Gingival Crevicular Fluid
A double-blind randomized-controlled clinical trial is conducted in order to evaluate the impact of non-surgical periodontal treatment by means of minimally invasive approach MINST or Q-SI (quadrantwise) approach in subjects with periodontitis on targeted metabolomics in gingival crevicular fluid
Read the detailed description
A double-blind randomized-controlled clinical trial is conducted in order to evaluate the impact of non-surgical periodontal treatment in subjects with periodontitis.
All the 60 patients with periodontitis are assessed for clinical, periodontal, and gingival crevicular fluid following of minimally invasive approach MINST or Q-SI (quadrantwise).
Measurements are taken before and after initial periodontal treatment in the periodontal subjects.
- Conditions
- Periodontitis

Questions about this trial
What is this clinical trial studying?
A study testing Probing depth reduction in people with Periodontitis, run by University of Catania at 1 site in Italy.
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 3 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: looking for participants now, as of the sponsor's last update on 31 Jul 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 Italy. 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?
This study is still under way. Results are not available in the source record yet.
How can a doctor refer a patient or contact the research team?
Contact Gaetano Isola (0953785652, gaetano.isola@unict.it), or a site near the patient. AzTrials does not enrol participants or take referrals.
What does the primary outcome measure?
Probing pocket depth (time frame: 6 months). 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 31 Jul 2026.
