Diode laser–assisted gum treatment for people with kidney transplants

Periodontal Status in Kidney Transplant Patients and the Effectiveness of Adjunctive Diode Laser Therapy

Not applicable Interventional Military Hospital 103 · NCT07532694

This project will test whether adding a diode laser to standard deep dental cleaning (scaling and root planing) helps people with periodontitis who have had a kidney transplant.

What this trial studies

This randomized, parallel-group trial will enroll 80 stable adult kidney transplant recipients with periodontitis and randomize them 1:1 to scaling and root planing (SRP) with adjunctive diode laser therapy or SRP alone. Clinical periodontal measures (CAL, PPD, BOP, GI, plaque indices) and radiographic alveolar bone changes will be collected at baseline, 1, 3, and 6 months. Systemic laboratory markers (platelet count, urea, creatinine, CRP) and subgingival microbiome profiles by 16S rRNA sequencing will be measured to capture biological effects. The study will compare whether the laser adjunct produces greater local periodontal and systemic improvements than SRP alone.

Who should consider this trial

Good fit: Adults (18+) who are medically stable kidney transplant recipients diagnosed with periodontitis and able to undergo non-surgical periodontal treatment and attend follow-up visits.

Not a fit: People who recently received periodontal treatment or systemic antibiotics, have an acute oral infection, are pregnant or clinically unstable, or cannot comply with scheduled visits are unlikely to benefit from participation.

Why it matters

Potential benefit: If successful, adjunctive diode laser therapy could improve gum attachment, reduce pocket depths and local inflammation, and possibly lower systemic inflammation in kidney transplant recipients.

How similar studies have performed: Previous studies in general dental populations have shown mixed or modest benefits from diode-laser adjuncts to SRP, and using this approach specifically in kidney transplant recipients is relatively novel.
