“…CP patients present increased production of systemic inflammatory cytokines (tumoral necrosis factor alpha [TNF-α], interleukin-1 beta , and interleukin-6 [IL-6]) (Górska et al 2003) which can induce the acute phase plasma protein synthesis, such as the C-reactive protein (CRP), (Craig et al 2003(Craig et al , loos 2005) and reduce the serum albumin level (hypoalbuminemia) (Kolte et al 2010, Amitha et al 2012, Saravanan et al 2012, Patil et al 2015. the acute phase response is the effort made by the organism to restore the homeostasis and eliminate the cause of imbalance, resulting in systemic effects (Loos 2005, Marcaccini et al 2009, Pradeep et al 2011 t h e p r i m a r y e t i o l o g i c a g e n t i s periodontopathogenic bacteria that can cause destruction of the periodontal tissues directly through the action of its components, particularly the lipopolysaccharide (lPS) present in the cell wall of gram-negative bacteria (e.g., Porphyromonas gingivalis, Tannerella forsythia, Prevotella intermedia), and indirectly, by stimulating the host cells to secrete inflammatory mediators that guide and regulate the destructive activity (Khattri et al 2017). thus, it is extremely important to stop and control the invasion of microorganisms in the subgingival environment as part of periodontal therapy, either with clinical subgingival scaling and root planning procedures or with systemic antibiotics (Van der Velden 2017, Drisko 2014).…”
