Methodology:~Group I (Periodontitis Group): 19 patients suffering from generalized periodontitis with T2DM age range, 35-50 years.~Group II (Periodontitis Group): 19 patients suffering from generalized periodontitis & systemically healthy, age range: 35-50 years.~Group III (Control group): 19 Periodontally and systemically healthy volunteers who served as control subjects age range: 30-45 years.~Periodontitis participants will be collected from the outpatient clinic of oral medicine and periodontology departments in Fayoum, Beni-Swief and Ahram-Candian universities. The periodontitis included subjects will be diagnosed according to the 2017 World Workshop on the Classification of Periodontal and Peri-Implant Diseases and Conditions (Tonetti, MS, Greenwell, H, Kornman, KS. Staging and grading of periodontitis: framework and proposal of a new classification and case definition. J Periodontol.; 89( Suppl 1): S159- S172, 2018.)~Diabetic patients will be enrolled in this study according to the criteria of American Diabetes Association. (American Diabetes Association. (2) Classification and diagnosis of diabetes. Diabetes Care 38: S8-S16, 2015.)~The control group will be selected from healthy subjects who attended the restorative dental clinic and has apparently clinically healthy gingiva.~Micropipettes will be used for collection of GCF samples for control group and periodontitis patients before & after periodontal treatment.~A complete mouth non-surgical periodontal therapy will be carried out for both periodontitis groups~The levels of IL-35 in the GCF samples were assessed using an ELISA kit following the guidelines by the manufacturer.
The sudy was aiming to assess and compare GCF levels of IL-39 & IL-35 in gingival crevicular fluid and to correlate the relationship between different patient groups before and after non-surgical therapy.
