What this trial studies

This clinical trial aims to evaluate the effectiveness of adjunct antimicrobial photodynamic therapy (aPDT) in conjunction with scaling and root planing for treating periodontal disease in obese patients. Participants will be divided into two groups, one receiving standard treatment and the other receiving aPDT alongside the standard treatment. The study will assess improvements in periodontal health and analyze changes in the proteomic profile of gingival fluid over a period of 6 months. The goal is to determine if aPDT enhances treatment outcomes compared to traditional methods alone.

Why it matters

Potential benefit: If successful, this approach could lead to improved periodontal health outcomes for obese patients suffering from periodontitis.

How similar studies have gone: While the specific combination of aPDT and periodontal treatment in obese patients is novel, similar studies have shown promising results with aPDT in periodontal therapy.
