Summary

Regulatory effects of some neuropeptides substance-P (SP), neurokinin-A (NKA), calcitonin gene-linked peptide (CGRP) and neuropeptide-Y (NPY) )on inflammatory responses in periodontal disease has been described; however, the impact of neuropeptide levels are not clearly defined in healthy and diseased peri-implant tissues.ın order to evaluate the situation, thirty-nine implants that have been loaded over the past 12 months and their symmetrically matching teeth were evaluated using a split-mouth study design. Clinical periodontal examinations included the Silness-Löe plaque index, Löe-Silness gingival index, bleeding on probing, probing pocket depth and clinical attachment level parameters were determined. Gingival crevicular fluid (GCF)/Periimplant sulcular fluid (PISF) samples were collected, and the levels of the neuropeptides were determined by enzyme-linked immunosorbent assay. Correlations between GCF/PISF neuropeptide levels and the clinical examination parameters were evaluated in the peri-implant/periodontal soft tissues.

TypeNameDescription
DIAGNOSTIC_TESTgingival crevicular fluid (GCF) and peri-implant sulcular fluid(PISF) collectionGCF/PISF samples were collected using periopaper strips. Prior to sample collection, each site was gently air-dried, all supragingival plaque was removed, and the area was carefully isolated to prevent samples from being contaminated by saliva.
