What this trial studies

This clinical trial investigates the effectiveness of Neodymium-Doped Yttrium Aluminum Garnet (Nd: YAG) Laser-assisted non-surgical periodontal treatment in patients with stage II/III periodontitis. Participants will receive laser treatment on one side of their mouth and standard scaling and root planing (SRP) on the other side, allowing for a direct comparison of outcomes. The study will assess changes in probing depth, gingival inflammation, and clinical attachment loss, as well as measure inflammatory markers and oxidative stress levels. Follow-up assessments will occur at baseline, 6 weeks, and 3 months post-treatment.

Who should consider this trial

Good fit: Ideal candidates are adults aged 18 to 65 diagnosed with stage II or III periodontitis.

Not a fit: Patients with fewer than 20 remaining teeth or those who have had recent periodontal treatment may not benefit from this study.

Why it matters

Potential benefit: If successful, this treatment could provide a more effective non-surgical option for managing moderate to severe periodontitis.

How similar studies have performed: Other studies have shown promising results with laser-assisted periodontal therapies, indicating potential for success in this approach.
