Peri-implant diseases and systemic inflammation: A preliminary analysis from a cross-sectional survey of patients with hypertension.

Abstract

The aim of this study was to investigate the association between peri-implant diseases and systemic inflammation assessed by serum C-reactive protein (CRP) levels in a sample of patients with hypertension. A total of 151 participants with hypertension were included in a cross-sectional study. The population was divided into six groups according to their peri-implant and periodontal status (healthy controls, mucositis, peri-implantitis, periodontitis, periodontitis and mucositis, periodontitis, and peri-implantitis). Linear, logistic regression, and correlation analyses were performed. CRP levels were statistically significantly higher in participants with periodontitis alone (median 3.2mg/L, interquartile range [IQR] 1.8, p=0.012), combined with mucositis (3.10mg/L, IQR 2.35, p<0.001) or peri-implantitis (2.7mg/L, IQR 2.53, p=0.002) when compared to the healthy controls (1mg/L, IQR 1.2). This association was independent of age, sex, smoking status, and adiposity differences. Participants with periodontitis with and without peri-implant diseases had the greatest odds of exhibiting CRP>3mg/L (odds ratio=7.3, 95% confidence interval 1.6-33.9). Peri-implant diseases are associated with systemic inflammation, but the nature of the association should be further investigated.
