Bactericidal Permeability Protein Inhibitor and Interleukin-1beta Levels After Non-surgical Periodontal Treatment

Gingival Crevicular Fluid (GCF) Bactericidal/Permeability-increasing Protein (BPI) and Interleukin (IL)-1beta in Periodontitis Patients: Non-surgical Periodontal Treatment Effects

The aim of this study was to examine the relationship between healing response after non-surgical periodontal treatment and baseline gingival crevicular fluid (GCF) levels of bactericidal/permeability-increasing protein (BPI) and interleukin-1beta (IL-1ß).

Bactericidal/permeability-increasing proteins (BPI) specific and powerful effect against Gram negative bacteria and their LPSs is completely observable in biological fluids such as plasma, serum, and whole blood.

Objective: It is the evaluation of periodontal disease effect of BPI and interleukin-1 beta (IL-1 β) levels in gingival fluid before and after non-surgical periodontal treatment (NSPT)in patients with periodontal disease.

Method: Thirty systemically healthy and non-smoking individuals with periodontitis were included in the study. Before NSPT, the clinical parameters of plaque index (PI), gingival index (GI), probing depth (PD), clinical attachment level (CAS), bleeding on probing (BOP) were measured. The gingival fluid samples were taken using the paper strip method. The same procedures were repeated at 6 weeks and 6 months after non-surgical periodontal treatment. ELISA method was used for the analysis of the samples
