Evaluation of Neutrophil Extracellular Trap Formation on Smokers and Non-Smokers with Periodontitis

Objevtive: In this study, we aimed to evaluate neutrophil extracellular trap (NET) in smoker and non-smoker periodontitis patients. Materials and Methods: 21 subjects [non-smokers and periodontally healthy (S-P-) 7 people, non-smokers with periodontitis (S-P+) 7 people, smokers with periodontitis (S+P+) 7 people] were included in this study. Plaque index (PI), gingival index (GI), probing depth (PD) and clinical attachment level (CAL) parameters were recorded. The peripheral neutrophils isolated from the subjects were activated by phorbol 12-myristate 13-acetate (PMA) to induce NET formation. NET formed after the activation was measured with the fluorometer. Results: In the S-P- group PI, GI, PD and CAL values were found statistically significantly low (P=0,001; P=
