Fenestration and dehiscence are said to be anatomical variations of cortical bone and not true pathological entities. They represent window-like defects covered by periosteum and overlying gingiva with or without the intact marginal bone. The etiology of such defects is still unclear, though many hypotheses such as occlusal traumatism, trauma, and variation in root bone angulation have been put forward. Diagnosis of such defects is challenging clinically, and they cannot be appreciated in conventional radiographs...

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 method by determination of the recovery rate, whole-blood samples were obtained with an anticoagulant from healthy donors, and platelet-rich plasma (PRP) fractions were clotted with CaCl 2 by centrifugation and digested with tissue-plasminogen activator...

Immediate implants are a valuable treatment option to replace natural teeth in the aesthetic region. The hypothesis of this randomized controlled clinical trial was that immediate implants grafted with autologous platelet-rich fibrin (PRF) have better clinical and radiographic outcomes than non-grafted controls. Forty-one implants were placed in 31 subjects with one or more non-restorable single-rooted teeth. Autologous PRF was placed in the peri-implant region of the study group (n=21) and no augmentation was done in the control group (n=20)...

Although horizontal tears of the meniscus have historically been treated with partial meniscectomy due to poor vascularity within the tear, evidence suggests that repair of horizontal meniscal tears may be advantageous to partial meniscectomy. Furthermore, the addition of platelet-rich plasma has shown promise in improving meniscal healing. We present our technique of platelet-rich fibrin clot-augmented repair of horizontal cleavage meniscal tear.

Immediate implant placement often presents challenges in terms of predictably obtaining soft-tissue coverage over the implant site. While delayed implant placement offers the ability for soft tissues to grow and invade the extraction socket making their attachment around implants more predictable, immediate implant placement poses a significant risk of bacterial invasion towards the implant surface as a result of insignificant soft-tissue volume. Soft-tissue grafting techniques have often been proposed for use during immediate implant placement to augment soft-tissue deficiencies, including the use of either palatal connective tissue grafts (CTGs) or collagen-derived scaffolds...
