What this trial studies

This investigation evaluates the clinical and radiographic outcomes of treating intrabony defects associated with chronic periodontitis using a minimally-invasive non-surgical therapy. The approach focuses on reducing bacterial load and promoting periodontal regeneration without the need for surgical intervention, which can be costly and unpredictable. Participants will undergo a treatment regimen that includes oral hygiene instructions and non-surgical periodontal therapy, specifically targeting deep intrabony defects. The study aims to provide a less invasive alternative to traditional surgical methods for managing periodontal disease.

Who should consider this trial

Good fit: Ideal candidates are adults aged 18-70 with a diagnosis of periodontitis and at least one intrabony defect.

Not a fit: Patients with a history of smoking, serious medical conditions, or those requiring prophylactic antibiotic coverage may not benefit from this study.

Why it matters

Potential benefit: If successful, this treatment could offer patients a safer and more effective way to manage chronic periodontitis and prevent tooth loss.

How similar studies have performed: Other studies have shown promise with minimally-invasive approaches for periodontal treatment, suggesting potential for success in this novel application.
