Summary

Periodontitis is a chronic inflammatory disease with multifactorial etiology. Although periodontal disease is initiated by pathogens within the biofilm layer, disease development and tissue destruction occur as a result of the interaction of periodontal pathogens and the host immune response. It has been determined in the literature that smoking has a significant negative effect on periodontal tissues and increases the risk of periodontitis by 2-5 times. It has been shown that there is a relationship between smoking and the incidence and progression of periodontitis. However, the mechanisms by which this occurs have not been explained. In this study, the effect of smoking on the levels of sclerostin (SOST), tumor necrosis factor-like weak inducer of apoptosis (TWEAK), receptor activator of nuclear factor-kB ligand (RANKL), and osteoprotegerin (OPG), which are effective in bone metabolism, in gingival crevicular fluid (GCF) and saliva will be evaluated. Participants in the study were in accordance with the 2017 World Workshop on Classification of Periodontal and Peri-implant Diseases and Conditions criteria as a result of clinical evaluations systemically healthy, non-smokers diagnosed with stage 2, 3 and/or 4 periodontitis (Group 1) (n=26); systemically healthy, diagnosed with stage 2, 3 and/or 4 periodontitis and smokers (Group 2) (n=26); systemically and periodontally healthy, non-smokers (Group 3-Control Group) (n=26). Clinical periodontal indixes will be obtained from participants meeting the inclusion criteria; GCF and saliva samples will be collected. The samples will be examined by ELISA test at Gazi University Faculty of Medicine, Department of Immunology.
