Characterization Of Leukocyte-Platelet Rich Fibrin, A Novel Biomaterial, Fadi K. Hasan Jan 2015

Characterization Of Leukocyte-Platelet Rich Fibrin, A Novel Biomaterial, Fadi K. Hasan

Theses and Dissertations

Autologous platelet concentrates represent promising innovative tools in the field of regenerative medicine and are successfully used in oral surgery. Several commercial systems exist that generate various forms of platelet concentrates including Platelet-rich plasma (PRP) and Platelet-rich fibrin (PRF). The alpha- granules of entrapped platelets release a variety of peptide growth factors that promotes healing. Usually PRP is a suspension that can be injected into the site of injury or used as a gel with the addition of thrombin (PRP-gel). In contrast Choukroun’s L-PRF is a dense fibrin based biomaterial enriched with platelets and growth factors. The physical state of …

Serum Anti-Phosphorylcholine And Anti-Cardiolipin Concentrations Following Periodontal Scaling And Root Planing, Reve W. Chaston

Theses and Dissertations

Atherosclerosis is an insidious disease with serious morbidity and mortality including ischemic heart disease, stroke, and myocardial infarction. This condition is progressive and can start early in life eventually leading to large plaques and arterial occlusion. Two key components of this process are the immune system and lipids; in particular, LDL which accumulates within the arterial walls and macrophages which recognize and engulf oxidized-LDL (oxLDL) to form foam cells. Knowing that certain antibodies directed against bacterial antigens such as phosphorylcholine (PC) and cardiolipin (CL) show opsonizing cross-reactivity with oxLDL it can be proposed that there is a link between immune …

C-Reactive Protein Levels In Generalized Aggressive Periodontitis Patients, Trang Nguyen Salzberg Jan 2004

C-Reactive Protein Levels In Generalized Aggressive Periodontitis Patients, Trang Nguyen Salzberg

Theses and Dissertations

Background: There is mounting evidence to indicate that periodontitis may be a risk factor for cardiovascular disease (CVD). Periodontitis may be linked to CVD as either an etiologic mechanism or a predisposing factor that can hasten disease progression. Proinflammatory cytokines, elevated fibrinogen, and platelet aggregation are all potential mechanisms. The purpose of this study is to compare and review the serological differences in subjects with severe periodontitis, some of which involve established risk factors for atherosclerosis, particularly heightened C-reactive protein levels. Methods: A total of 184 subjects, comprising of two periodontal subgroups, non-periodontal (NP = 91) and generalized aggressive periodontitis …
