Effect of Different Centrifuge Values on Saliva High Sensitive C-Reactive Protein (Hs-CRP) Levels in Individuals With Different Smoking Amounts

The purpose of this study; In periodontally healthy individuals, high sensitive c-reactive protein (hs-CRP) levels of non-smokers, smokers of less than 10 cigarettes per day and smokers of more than 10 cigarettes per day were measured at 15 rpm-10 min, 10 centrifuge values, which are frequently used in saliva studies. To determine the levels in saliva samples as a result of rpm-10 min and 10 rpm 6 min centrifugations and to determine the values at which a cytokine of this molecular weight should be centrifuged and to examine the possible correlation between these values and the clinical parameters of the amount of smoking. Materials and Methods: saliva samples were collected from 90 systemically healthy individuals who were non-smokers (N, n=30), light smokers \<10 cigarettes per day (L, n=30) and heavy smokers \>10 cigarettes per day (H, n=20). samples were taken. Full-mouth clinical periodontal measurements, including probing depth (PD), clinical attachment level (CAL), bleeding on probing (BOP), gingival index (GI), and plaque index (PI), were also recorded. Enzyme-linked immunosorbent assay (ELISA) was used to determine hs-CRP levels in biological samples.
