NCT06545084

Brief Summary

The purpose of the study is to evaluate peri-radicular healing after root-end surgery using Leukocyte and Platelet Rich Fibrin. The study population includes patients diagnosed with persistent periapical pathology and scheduled for Endodontic Microsurgery at the University of Pennsylvania School of Dental Medicine, Department of Endodontics. Patients undergoing routine endodontic microsurgery and who meet the inclusion criteria will be given the opportunity to opt in to receive L-PRF in the osteotomy site to promote bone formation. Healing will be assessed radiographically and clinically at six, twelve, eighteen, and twenty-four months.

Outcome Measures

Primary Outcomes (1)

  • Peri-radicular Healing

    Evaluate Peri-radicular healing after Endodontic Microsurgery with the use of autologous L-PRF plug.

    12 and 24 months

Interventions

Leukocyte Platelet Rich Fibrin (L-PRF) is a collection of growth factors rich in proinflammatory cells that promote healing after dental surgery. A L-PRF clot is obtained by collecting blood from the subject, similar to a phlebotomist drawing blood via venipuncture. The blood samples are spun in a centrifuge using the recommended settings by the manufacture(1). The resultant product has separated the red blood cells from the L-PRF clot which is placed back into the subject to promote healing of the surgical site.
