Non Surgical Periodontal Treatment Effect on Il-17 and Il-18 in Aggressive Periodontitis

Aggressive Periodontitis

gingival crevicular fluid

clinical parameters and IL-17 and Il-18 GCF levels were measured in 25 aggressive periodontitis patients compared to 25 periodontally healthy individuals. It was observed that that Clinical parameters and Il-17 and Il-18 levels are higher before treatment but decreased after treatment which suggests role of these interleukins in pathogenesis of aggressive periodontitis .

Aggressive periodontitis is a type of rapidly progressing periodontal diseases .The three classic primary characteristics of this disease are ; occurring in young healthy patients with rapid attachment loss and familial aggregation .Bacteria-host interactions, insufficiencies in host defenses and possibly a genetic predisposition represent the etiologic factors . Beside the young age of onset, important factors as involvement of host factors and non-plaque-related etiologic factors have also been proposed . Aim of the study: Objectives were to compare and correlate the clinical parameters and biochemical parameters (Il-17 and Il-18 levels in GCF) of aggressive periodontitis patients (At baseline and after three months of nonsurgical treatment) versus periodontally healthy subjects at baseline. Subjects and methods: Populations included in the study: A total of fifty individuals were enrolled and categorized as; group A that included twenty five aggressive periodontitis patients and group B which included twenty five periodontally healthy controls. Clinical parameters: Plaque index (PI) ,gingival index (GI), Probing pocket depth (PPD) and clinical attachment level (CAL) were measured at baseline for both groups and after three months of non surgical periodontal treatment completion for group A. GCF sampling: In group A ,the site with deepest probing depth was selected for GCF sampling while for group B , any site was sampled using PerioPaper strips . Phase I periodontal treatment After baseline GCF sample collection and clinical measurement recordings, group A patients received phase I periodontal treatment. Analysis of Il-17 and Il-18 levels in GCF: GCF samples were examined by enzyme-linked immunosorbent assay (ELISA).Procedures were performed according to the directions in the kits.
