Overview

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.

FAQs

Learn more about clinical trials

What is a clinical trial?

A clinical trial is a study designed to test specific interventions or treatments' effectiveness and safety, paving the way for new, innovative healthcare solutions.

Why should I take part in a clinical trial?

Participating in a clinical trial provides early access to potentially effective treatments and directly contributes to the healthcare advancements that benefit us all.

How long does a clinical trial take place?

The duration of clinical trials varies. Some trials last weeks, some years, depending on the phase and intention of the trial.

Do I get compensated for taking part in clinical trials?

Compensation varies per trial. Some offer payment or reimbursement for time and travel, while others may not.

How safe are clinical trials?

Clinical trials follow strict ethical guidelines and protocols to safeguard participants' health. They are closely monitored and safety reviewed regularly.
