What this trial studies

This study evaluates the healing of periapical tissues following endodontic microsurgery with the application of Leukocyte and Platelet Rich Fibrin (L-PRF). Patients diagnosed with persistent periapical pathology and scheduled for surgery at the University of Pennsylvania will have the option to receive L-PRF to enhance bone formation at the surgical site. Healing will be monitored through clinical and radiographic assessments at intervals of six, twelve, eighteen, and twenty-four months post-surgery.

Who should consider this trial

Good fit: Ideal candidates are adults over 18 years old with persistent endodontic periapical pathology and in good general health.

Not a fit: Patients with suspected root fractures or those classified as ASA 3 or greater will not benefit from this study.

Why it matters

Potential benefit: If successful, this approach could improve healing outcomes for patients undergoing endodontic microsurgery.

How similar studies have performed: While the use of L-PRF in dental procedures is gaining interest, this specific application in endodontic microsurgery is relatively novel and has not been extensively tested.
