Subjects and methods: The present study was conducted on 25 individuals Ten of the individuals were healthy and representing the control group, group (A) and 15 were suffering from chronic periodontitis representing group (B). Gingival crevicular fluid samples were collected from both study groups to detect IL-21 levels. Regarding the assessment of IL-21, ELISA technique was used. Group (B) was subjected to scaling and root planing and then were recalled after 4 months from treatment to resample the gingival crevicular fluid and evaluate the changes in clinical parameters after the nonsurgical periodontal treatment. Then all the detected data was subjected to statistical analysis UR - http://172.23.153.220/th.pdf ER -
