What this trial studies

This study evaluates the impact of leucocyte and platelet rich fibrin Block (L-PRF Block) on post-operative comfort and bone healing in patients undergoing endodontic microsurgery for large peri-apical lesions. It is designed as an open randomized controlled trial with two groups: one receiving the L-PRF Block during the procedure and the other receiving standard care without it. The aim is to determine whether the addition of L-PRF Block improves outcomes for patients with significant periapical lesions.

Who should consider this trial

Good fit: Ideal candidates are adults aged 18 and older who require endodontic microsurgery for large periapical lesions.

Not a fit: Patients who are not suitable for endodontic microsurgery or have significant systemic diseases may not benefit from this study.

Why it matters

Potential benefit: If successful, this approach could enhance patient comfort and promote better healing of bone tissue after endodontic procedures.

How similar studies have performed: While the use of L-PRF in various surgical contexts has shown promise, this specific application in endodontic microsurgery is relatively novel and has not been extensively tested.
