Diode laser added to deep cleaning for gum disease.

Official title: Evaluation of the Effect of Adjunctive Diode Laser Therapy in Mechanical Scaling and Root Surface Debridement in Non-Surgical Periodontal Therapy

Run by Tel Aviv University · NCT07446127 · Data updated 2026-11-12

This test will see if adding a 940-nm diode laser to deep cleaning helps adults with periodontal pockets and attachment loss more than deep cleaning alone.

Is this trial a fit for you?

Likely a good fit

Adults who are systemically healthy, have at least 20 teeth with significant periodontal pockets (≥30% of sites and ≥2 teeth per quadrant with probing depths ≥5 mm) and radiographic bone loss are ideal candidates.

Probably not a fit

Smokers, people with systemic diseases affecting the periodontium, those on medications that affect periodontal status, pregnant or lactating women, and patients who had periodontal treatment within the past 12 months are excluded and unlikely to benefit from this protocol.

What this trial studies

This randomized split-mouth trial compares standard non-surgical root surface debridement (scaling and root planing) alone to the same treatment with adjunctive 940-nm diode laser therapy, with quadrants in each patient randomly assigned to one of the two approaches. Eligible, systemically healthy adults must have at least 20 teeth, at least five teeth per quadrant, ≥30% of sites involved, and at least two teeth per quadrant with probing depths ≥5 mm and radiographic bone loss. Clinical periodontal outcomes such as probing depth reduction and changes in clinical attachment level will be measured to compare effectiveness between treatments. The trial is conducted at a single center affiliated with Tel Aviv University in Afula, Israel.

Why it matters

Potential benefit: If successful, adding diode laser therapy could produce greater pocket depth reduction and better attachment level preservation than cleaning alone.

How similar studies have gone: Previous studies of adjunctive diode lasers with scaling and root planing have shown mixed results, with some reporting modest additional pocket depth reduction while overall evidence remains inconclusive.
