Comparative histologic evaluation of titanium platelet-rich fibrin and platelet-rich fibrin in hypertensive and smoker participants: A cell cytology study

Introduction: In recent years, a growing interest has emerged with the use of platelet-rich products for the treatment of many clinical conditions in dentistry. Objective: The present study aimed to define the structural characteristics of titanium platelet-rich fibrin (TPRF) and PRF in hypertensive and smoker participants . Materials and Methods: Ten milliliters of blood samples was drawn using a syringe form ninety participants (healthy, hypertensive, and smokers). Five milliliters of blood was transferred to each of dry glass tube and titanium tube. The clot obtained after centrifugation from each tube was processed for light microscopy analysis. Results: The TPRF samples have demonstrated a highly organized and thicker fibrin network with continuous integrity as compared to PRF in healthy participants. The hypertensive and smokers showed less prominent fibrin border between the cellular structures in both the platelet concentrates, but sufficient fibrin mesh network was found in TPRF clot as compared to PRF clot in the test participants. Conclusion: This is the first human histologic study to define the fibrin meshwork in both TPRF and PRF clots in hypertensive and smokers. The platelet activation by titanium offered high characteristics to fibrin network.
