Comparative Evaluation of C-Reactive Protein Levels among Peri-Implant Health and Disease Conditions

Peri-implant disease pathogenesis results in production of pro-inflammatory mediators, among which C-reactive protein (CRP) is one of the acute phase reactants. The aim of the study was to comparative CRP levels among peri-implant health and disease conditions. The present study was carried out in the Department of Implantology, Saveetha Dental College and Hospitals, Chennai, India. A total of 40 patients with peri-implant health (n = 10), peri-mu-cositis (n = 10), early peri-implantitis (n = 10) and advanced peri-implantitis (n = 10) were enrolled. Unstimulated salivary samples were collected and subjected to latex agglutination assay for CRP analysis. CRP levels were then correlated with peri-implant health and diseases. CRP level in peri-implant health, peri-implant mucositis, early peri-implantitis and advanced peri-implantitis were 0.18 ± 0.04 mg/dL, 2.05 ± 0.61 mg/dL, 4.14 ± 1.82 mg/dL and 6.21 ± 1.35 mg/dL respectively. There was a statistically significant difference in CRP levels between all the tested groups (ANOVA, P = 0.03). Pearson correlation coefficient analysis revealed a strong positive correlation between CRP and peri-implant health status. CRP level was high among patients with peri-implantitis followed by peri-implant mucositis and peri-implant health. Also, CRP level increases with severity of peri-implant diseases and there exists a positive correlation between CRP level and peri-implant health status. © 2024 by Begell House, Inc.
