GCF IL-17 Levels and Oxidative Status of Smoking and Non-smoking Individuals With Periodontitis

Study Overview
=================
Brief Summary
-----------------
This study was performed to evaluate the effects of both periodontal treatment and smoking on the gingival crevicular fluid(GCF) levels of interleukin (IL)-17A, IL-17E, Total oxidative stress(TOS) and total antioxidant capasity(TAOC) in smoking and non-smoking patients with severe chronic periodontitis. Systemically healthy 15 smoker,15 non-smoker with chronic periodontitis were attended for the study. Periodontal status were determined by recording periodontal clinical measurements. GCF samples were collected at the baseline, at the end of initial periodontal treatment and 4 weeks after periodontal flap surgery. The data were tested statistically by the Student t and paired sample t tests.

What is the study measuring?
-----------------
Primary Outcome Measures

| Outcome Measure | Measure Description | Time Frame |
| --- | --- | --- |
| GCF IL-17A VOLUME | IL-17A is a cytokine present in gingival crevicular fluid. Its volume calculated as microliter and changes due to inflammation caused by periodontal disease. | GCF sampling was performed prior to periodontal treatment , 4 weeks after completion of initial periodontal treatment, and 4 weeks after periodontal flap surgery . | 
| GCF IL-17E VOLUME | IL-17E is a cytokine present in gingival crevicular fluid. Its volume calculated as microliter and changes due to inflammation caused by periodontal disease. | GCF sampling was performed prior to periodontal treatment , 4 weeks after completion of initial periodontal treatment, and 4 weeks after periodontal flap surgery . | 
| GCF TOTAL OXIDATIVE STRESS (TOS) LEVEL | TOS is the measurement of oxidative stress amount and given as mmol/L unit. Its amount changes due to inflammation caused by periodontal disease. | GCF sampling was performed prior to periodontal treatment , 4 weeks after completion of initial periodontal treatment, and 4 weeks after periodontal flap surgery . | 
| GCF TOTAL ANTIOXIDANT CAPASITY (TAOC) | TAOC is the antioxidant amount measured and given as μmol H2O2 Eq/L unit. Its amount changes due to inflammation caused by periodontal disease. | GCF sampling was performed prior to periodontal treatment , 4 weeks after completion of initial periodontal treatment, and 4 weeks after periodontal flap surgery . |
