Comparing two treatments for intra-bony periodontal defects

Rh-PDGF Versus Emdogain for Treatment of Intra-bony Defects

Phase1; Phase2 Interventional Nova Southeastern University · NCT05442034

This study is testing whether a new treatment using growth factors works better than a standard treatment for helping adults with deep gum pockets heal and regain healthy gum tissue.

What this trial studies

This clinical trial aims to evaluate the effectiveness of recombinant human platelet-derived growth factor (GEM-21) versus enamel matrix derivatives (EMD) in treating intra-bony periodontal defects. Patients aged 18 and older who have persistent deep probing depths after scaling and root planing will be randomly assigned to receive one of the two treatments combined with an allogenic bone graft. The study will follow participants for six months to assess clinical attachment gain, pocket depth reduction, and radiographic bone height improvement. The trial seeks to enhance understanding of periodontal regeneration techniques and their outcomes.

Who should consider this trial

Good fit: Ideal candidates include adults over 18 with specific intra-bony defects and a history of periodontal disease.

Not a fit: Patients with uncontrolled diabetes, heavy smokers, or those on certain medications may not benefit from this study.

Why it matters

Potential benefit: If successful, this study could lead to improved treatment options for patients with intra-bony periodontal defects, enhancing their periodontal health.

How similar studies have performed: Previous studies have shown promising results with similar regenerative approaches, indicating potential for success in this trial.
