Platelet-rich plasma is an autologous product that is derived from whole blood through the process of gradient density centrifugation. The proposed value of this product in dental implantology and in bone augmentation procedures lies in the ability to incorporate high concentrations of the growth factors PDGF TGF-beta1, TGF-beta2, and IGF as well as fibrin, into the graft mixture. Research has ...

Amaç: Rejeneratif endodontide son çalışmalar tedavinin farklı kök gelişim tipleri gösterdiğini ortaya çıkarmıştır. Chen ve indeksinde rejeneratif endodontik tedavi sonrasında 5 tipi rapor edilmiştir. Bu çalışmanın amacı tedavide kullanılan trombositten zengin plazma (PRP) fibrin (PRF) iskelelerinin yanıt üzerine etkisini değerlendirmektir. Gereç Yöntemler: çalışmada görmüş 38 tane vaka retrospe...

In the recent years, the unique characteristics of mesenchymal stem cells (MSCs), consisting their angiogenesis and vascularization activity, as well as anti-inflammatory, anti-ulcer and immunosuppressive features plusdifferentiation capability into multilineage cell, have provided huge favorite among clinicians and researchers that theirs experiments has focused on treatment of different disea...

Focal chondral lesions of the glenohumeral joint, though less common than chondral defects in the knee or ankle, can be a significant source of pain in an active population. For patients in whom nonsurgical management fails, promising results have been reported after arthroscopic microfracture surgery to treat such lesions. However, microfracture leads to growth of fibrocartilage tissue and is ...

INTRODUCTION Leukocyte-platelet rich fibrin belongs to a second generation of platelet concentrates that does not need biochemical blood manipulation. It is used for tissue healing and regeneration in periodontal and oral-maxillofacial surgery. We report two cases of hyperplastic gingival lesions treated by exeresis and application of leukocyte-platelet rich fibrin membranes in order to improve...

Platelet-rich fibrin (PRF) clots have been used in regenerative dentistry most often, with the assumption that growth factor levels are concentrated in proportion to the platelet concentration. Platelet counts in PRF are generally determined indirectly by platelet counting in other liquid fractions. This study shows a method for direct estimation of platelet counts in PRF. To validate this meth...

Platelet-Rich Fibrin (PRF) was first described by Choukroun et al., (2001). It has been referred to as a second-generation platelet concentrate, which has been shown to have several advantages over traditionally prepared platelet-rich plasma. PRF has a physiologic architecture that is very favourable to the healing process, obtained due to the slow polymerization process. The development of pla...

Thrombin cleavage of blood coagulation Factor XIII (a2b2) and fibrinogen was studied during in vitro clotting to determine the physiologic sequence of these events. First, the time course of fibrin formation and cleavage of Factor XIII was measured in platelet-rich plasma. Cleavage of fibrinogen was measured by using a radioimmunoassay for fibrinopeptide A. Conversion of trace amounts of radioi...
