Effect of suturing in root coverage via coronally advanced flaps: A systematic review

Clinical Advances in Periodontics, EarlyView.
Abstract Background To analyze the evidence about the influence of the suturing technique and material in terms of the percentage of mean root coverage (%MRC) following root coverage therapy in teeth diagnosed with single/localized gingival recession defects (GRD) via a monolaminar coronally advanced flap. Methods The protocol of this systematic review

Multiscale Network Model for Fibrin Fibers and Fibrin Clot with Protofibril Binding Mechanics [PDF]

arXiv, 2018
The multiscale behavior of the individual fibrin fibers and fibrin clots is modeled by coupling atomistic simulation data and microscopic experimental data. We propose a protofibril element made up of nonlinear spring network, constructed based on the molecular simulation and atomic force microscopy results to simulate the force extension behavior of ...

Bulk fluid phase behaviour of colloidal platelet-sphere and platelet-polymer mixtures [PDF]

, 2012
Using a geometry-based fundamental measure density functional theory, we calculate bulk fluid phase diagrams of colloidal mixtures of vanishingly thin hard circular platelets and hard spheres. We find isotropic-nematic phase separation with strong broadening of the biphasic region upon increasing the pressure.

Platelet-rich Fibrin for Chronic Wounds Management [PDF]

, 2022
Background: A chronic wound can be defined as any wound that fails to heal within a reasonable period. Platelet-rich fibrin (PRF) is a second-generation platelet concentrate.

In vitro ultrastructure and biodegradation of activated plasma albumin gel derived from human samples: A prospective observational study

Clinical Advances in Periodontics, EarlyView.
Abstract Background In soft tissue regeneration, the clinical efficacy of fibrin membranes has been a pressing concern. The key to this efficacy lies in the stability of membrane and its controlled absorption. Human serum albumin, with its influence on the formation and stability of fibrin networks, could hold the key to developing a more stable ...

Different regenerative responses of two platelet concentrates in the treatment of human periodontal infrabony defects: A clinico-radiographic study

Contemporary Clinical Dentistry, 2020
Background: Platelet concentrates usage in the treatment of intrabony defects has been improved due to advancement of research. Many generation of platelet concentrates were used, but research regarding advanced platelet-rich fibrin (A-PRF) regarding ...

Non-canonical proteolytic activation of human prothrombin by subtilisin from Bacillus subtilis may shift the procoagulant\ue2\u80\u93anticoagulant equilibrium toward thrombosis [PDF]

, 2017
Blood coagulation is a finely regulated physiological process culminating with the factor Xa (FXa)-mediated conversion of the prothrombin (ProT) zymogen to active -thrombin (T).

Crestal approach for repair of oroantral bone defects and subsequent implant placement

Clinical Advances in Periodontics, EarlyView.
Abstract Background Oroantral communication (OAC) can occur after a dental extraction. Occasionally, bony defects may persist despite successful soft tissue closure of the OAC. The absence of bone in these areas poses challenges for dental implant placement.

Thermoresponsive stiffening with microgel particles in a semiflexible fibrin network [PDF]

, 2019
We report temperature-responsive soft composites of semiflexible biopolymer networks (fibrin) containing dispersed microgel colloidal particles of poly(N-isopropylacrylamide) (pNIPAM) that undergo a thermodynamically driven de-swelling transition above a Lower Critical Solution Temperature (LCST). Unlike standard polymer-particle composites, decreasing
