PRF Membrane and Recovery After Periapical Surgery: A 3D Imaging Study

Evaluation of PRF Membrane in Postoperative Recovery: A Preliminary Study Using 3D Imaging in Periapical Surgery

The goal of this clinical trial is to determine whether a PRF (platelet-rich fibrin) membrane helps improve recovery after periapical surgery in adults. The main questions it seeks to answer are:

Does the use of a PRF membrane reduce swelling and pain after surgery? Does the use of a PRF membrane improve healing as observed on 3D imaging? Researchers will compare the outcomes of participants who receive a PRF membrane during surgery with those who do not, to assess whether the PRF membrane improves recovery.

Participants will:

Undergo periapical surgery with or without the use of a PRF membrane. Have swelling and pain assessed at specific time points after surgery. Participate in 3D imaging scans to evaluate healing.

Participants will:

Undergo periapical surgery with or without the use of a PRF membrane. Have swelling and pain measured at specific time points after surgery. Take part in 3D imaging scans to evaluate healing.
