Clinical Trial Summary

Injectable platelet-rich fibrin (I-PRF) is a flowable blood concentrate that is entirely natural and allows ease of access and flow within the root canal. It was first developed in 2014 by modifying the centrifugation parameters. I-PRF has great potential in the field of endodontics. At present, it is still in its infancy and needs to be explored with regard to its regenerative efficacy.

To the best of our knowledge, this study is the first to clinically and comparatively investigate Platelet-rich plasma (PRP) and I-PRF.


Description:

An ideal treatment option for an immature necrotic tooth is the regeneration of pulp-like tissue that is capable of boosting the continuation of normal root development. The use of platelet concentrates for that purpose is a clinically relevant, minimally invasive approach which has a promising potential of reducing the healing period. Among which, the most commonly employed is the Platelet-Rich Plasma that is not entirely natural. It involves the use of non-autologous anticoagulants such as bovine thrombin to maintain the fluid consistency which prevents clot formation and thus impairs wound healing, affects the coagulation process and can also trigger an immune reaction, thereby, suppressing regeneration.

PRP offers a short-term release of most of the growth factors unlike the Platelet-Rich Fibrin which allows for a more sustained release. PRF does not require any biochemical handling of blood and is easy to procure but due to the gel-like consistency, its adaptability within the root canal requires excessive removal of root dentin.

In addition, the application of recombinant growth factors within the root canal is associated with high cost which hinders its applicability in the common clinical practice.

Therefore, a new regenerative technique is required that combines the advantages of both PRP and PRF while overcoming their drawbacks.

Intervention

Procedure:
Injectable platelet-rich fibrin
A blood sample will be drawn from the patient, centrifuged at 700 rpm for 3 minutes and the upper yellow fluid will be collected by a plastic syringe, avoiding the inclusion of the red blood cells underneath, and will be introduced within the root canal.
Platelet-rich plasma
A blood sample will be drawn from the patient, centrifuged at 3000 rpm for 10 minutes and the upper yellow fluid will be collected by a plastic syringe, avoiding the inclusion of the red blood cells underneath, and will be introduced within the root canal.
