Comparison of Salivary Neuropilin-1 (NRP-1), Cotinine and C-Reactive Protein (CRP) Levels With Periodontal Clinical Parameters in Smokers and Non-Smokers With Different Periodontal Diseases

Periodontal Diseases Clinical Trial

Official title:
Comparison of Salivary Neuropilin-1 (NRP-1), Cotinine and C-Reactive Protein (CRP) Levels With Periodontal Clinical Parameters in Smokers and Non-Smokers With Different Periodontal Diseases

Clinical Trial Summary

In order to determine the pathogenesis of chronic inflammatory diseases, the levels of various cytokines are analysed in tissues and fluids taken from the body. In various publications, the role of the glycoprotein sNRP-1 on inflammatory diseases and the relationship between smoking and periodontal diseases have been investigated. In this study, our aim was to evaluate the levels of this biomarker in the saliva of smokers with systemically healthy periodontitis and non-smokers with systemically healthy periodontitis, gingivitis and periodontal disease and to compare the concentration differences with CRP. Another aim is to show the effect of nicotine exposure rate on all these by measuring cotinine levels. In our study, all oral clinical parameters of 80 patients, including 20 systemically healthy, non-smoking and periodontally healthy patients, 20 patients with gingivitis, 20 patients with periodontitis; 20 systemically healthy, smoking patients with periodontitis, will be measured and saliva samples will be taken from the patients. The sNRP-1, cotinine and CRP levels in the samples will be determined by enzyme-linked immunoassay (ELISA). Then, statistical analyses will be performed and the difference in the levels of biomarkers between the groups will be interpreted. Possible significant differences between the levels of these biomarkers may reveal that sNRP-1 can be used as a diagnostic tool in periodontal diseases or as a guide for treatments to be performed and may reveal a new perspective on the relationship between periodontitis and smoking.
