What this trial studies

This study investigates the effectiveness of a spermidine-based gel as an addition to minimally invasive non-surgical periodontal therapy (MINST) for treating periodontitis. The primary goal is to determine if the spermidine gel can significantly reduce pocket depth compared to MINST alone. Secondary outcomes include assessing other periodontal health indicators such as bleeding on probing and clinical attachment loss over a 12-month period. Participants will be monitored to evaluate the overall improvement in their periodontal health.

Who should consider this trial

Good fit: Ideal candidates are adults aged 18 and older with untreated periodontitis showing specific clinical attachment loss and probing depth.

Not a fit: Patients with systemic diseases, smokers, pregnant or breastfeeding women, or those with allergies to study products may not benefit from this study.

Why it matters

Potential benefit: If successful, this approach could enhance periodontal health outcomes for patients suffering from periodontitis.

How similar studies have performed: While the use of spermidine in periodontal therapy is relatively novel, similar adjunct therapies have shown promise in improving periodontal outcomes in other studies.
