Abstract
Following inflammation and bone loss near the implant site, peri-implantitis develops. N-Telopeptide (NTx) and Calprotectin are abundant in the crevicular fluids found in that area and are thought to be possible biomarkers. Therefore, it is of interest to evaluate the amounts of calprotectin and NTx in the peri-implant sulcular fluid (PISF) from implant sites with or without peri-implantitis. Twenty healthy individuals and twenty patients with peri-implantitis who had a single dental implant were included in the total of forty participants. For every patient, the peri-implant clinical parameters of gingival index (GI), probing depth (PD) and bleeding on probing (BOP) were ted. To evaluate the bone loss (BL), radiographic pictures of every implant were acquired. Using sterile paper strips, PISF was gathered in order to use the ELISA technique to measure the amounts of NTx and calprotectin. We examined the correlations between the levels of PISF, NTx and calprotectin with the peri-implant clinical indicators. In comparison to the healthy group, the peri-implantitis group had increased levels of NTx and calprotectin. In individuals with peri-implantitis, the levels of NTx and calprotectin in the PISF may be a promising indicator for bone loss and peri-implant inflammation.
