Impact of Centrifuge Speed on Saliva Protein Levels in Smokers

Official title: Evaluating the Effect of Smoking Amount on Determining Salivary High Sensitive C-Reactive Protein(Hs-CRP) Values by Centrifuging the Saliva of the Same Individuals at Different Rpm and Time.

Run by Izmir Katip Celebi University · NCT06561971 · Data updated 2026-11-12

This study tests how different speeds of a machine that spins saliva samples can change the levels of a specific protein in the saliva of smokers and non-smokers to better understand the effects of smoking on oral health.

Is this trial a fit for you?

Likely a good fit

Ideal candidates include systemically healthy individuals who are either non-smokers, light smokers (less than 10 cigarettes per day), or heavy smokers (more than 10 cigarettes per day) with no recent periodontal treatment.

Probably not a fit

Patients with oral or systemic diseases, those on regular medication, or individuals who have received recent periodontal treatment will not benefit from this study.

What this trial studies

This study investigates how different centrifuge speeds affect the levels of high sensitive C-reactive protein (hs-CRP) in saliva among individuals with varying smoking habits. It involves collecting saliva samples from 90 healthy participants categorized as non-smokers, light smokers, and heavy smokers. The samples will be centrifuged at different speeds to determine the optimal conditions for measuring hs-CRP levels and to explore any correlations with clinical parameters related to smoking. The study aims to enhance understanding of the biochemical effects of smoking on oral health.

Why it matters

Potential benefit: If successful, this study could provide insights into the relationship between smoking and inflammation, potentially guiding better oral health management for smokers.

How similar studies have gone: While there may be studies examining hs-CRP levels in relation to smoking, the specific focus on centrifuge speeds and saliva analysis in this context appears to be a novel approach.
