What this trial studies

This clinical trial investigates the effectiveness of laser disinfection and ICG-mediated photodynamic therapy as adjuncts to root surface debridement in patients with periodontitis. Participants will receive full-mouth supragingival debridement and will be randomly assigned to either a control group or treatment groups that will receive additional therapies. The study aims to assess improvements in clinical parameters and reductions in periodontal pathogens after treatment. All patients will follow a standardized oral hygiene regimen throughout the trial.

Who should consider this trial

Good fit: Ideal candidates are adults over 18 years old, non-smokers, diagnosed with generalized periodontitis, and not currently undergoing other periodontal treatments.

Not a fit: Patients who smoke, have systemic diseases like diabetes, or have received recent periodontal treatment may not benefit from this study.

Why it matters

Potential benefit: If successful, this approach could lead to more effective treatments for periodontitis, improving oral health outcomes for patients.

How similar studies have performed: While similar approaches have been explored, this specific combination of therapies is novel and has not been extensively tested in prior studies.
