nspt on vitronectin and fetuin-a levels in patients with periodontitis and coronary artery disease

Conditions: Chronic Periodontitis; Cardiovascular Diseases; Periodontal Inflammation

Summary: periodontitis is a chronic inflammatory disease mainly caused by the oral microbial biofilm. it involves the periodontal supporting tissues mainly features gum inflammation, alveolar bone resorption, periodontal pocket formation, and tooth loosening but also induces various systemic diseases, which seriously affect the physical and mental health of patients. the response to periodontal infection is mediated by various intracellular signalling pathways leading to the production of numerous bio-molecules. vitronectin is a multifunctional protein with a multiple binding domain that interacts with a variety of plasma and cell proteins. it belongs to the group of adhesive glycoproteins that is involved in various functions including complement activation, blood coagulation, binding to proteoglycans, and modification of the matrix. among the various cystatins expressed in serum and saliva, fetuin-a, an another protein is produced majorly by healthy hepatic and adipose tissues. fetuin-a has been recognized as a multifunctional molecule related to its role in metabolic processes, insulin resistance, regulation of adipogenesis and mineralization throughout the body. the study aims to determine the expression of vitronectin and fetuin-a as potential pro-inflammatory and anti-inflammatory biomarkers respectively. these protein molecules can further play a role as putative risk indicators in periodontitis subjects with and without coronary artery disease following non-surgical therapy.
