Official title: Effects of Minimally Non-surgical Periodontal Treatment Versus Quadrantwise Subgingival Instrumentations on Targeted Metabolomics in Gingival Crevicular Fluid
Run by University of Catania · NCT07740447 · Data updated 2026-11-12

Is this trial a fit for you?
✓Likely a good fit
Adults diagnosed with periodontitis who have not received periodontal treatment or antibiotics/NSAIDs/immunosuppressants in the last 6 months and are not pregnant.
✕Probably not a fit
Patients previously treated for periodontitis within the last 6 months or those taking conflicting medications may see limited benefit.

What this trial studies
Sixty adults with periodontitis are randomly assigned in a double-blind design to receive minimally invasive non-surgical periodontal treatment via MINST or quadrant-wise Q-SI. Measurements of clinical and periodontal outcomes, plus gingival crevicular fluid metabolites, are taken before and after initial treatment. The trial focuses on how these treatments affect targeted metabolomics in the gum fluid while monitoring standard periodontal health indicators. Probing depth reduction is the primary intervention outcome. The study is conducted at AOU Policlinico G. Rodolico in Catania, Italy, with University of Catania as lead sponsor.
Why it matters
Potential benefit: If successful, patients could experience improved periodontal health and clearer metabolomic markers indicating treatment response.
How similar studies have gone: Previous research has explored minimally invasive periodontal approaches, with some showing favorable clinical outcomes; metabolomic analyses in this area are ongoing and not yet definitive.
