摘要

This cross-sectional study was to investigate the associations of self-reported oral health, tooth loss, interdental cleaning and dental visits with serum C-reactive protein (CRP). Data regarding oral health questionnaires, dentition examination and serum high-sensitivity CRP from 6358 participants aged 30 − 80 years were analyzed in US National Health and Nutrition Examination Survey 2015 − 2020. Weighted linear regression analyses were performed. In the fully adjusted model, very good or excellent self-reported oral health was associated with lower ln-transformed serum CRP compared to poor or fair self-reported oral health (regression estimates (β) and 95% Confidence interval (CI): -0.106(-0.196, -0.016), P = 0.037). Further multivariate analyses demonstrated a positive association between the number of missing teeth and ln-transformed serum CRP (β and 95% CI: 0.010(0.001, 0.019), P = 0.047), while interdental cleaning frequency was inversely associated with ln-transformed serum CRP (day/week of performing interdental cleaning β and 95% CI: -0.024(-0.041, -0.008), P = 0.010). No significant association was observed between time since last dental visit and ln-transformed serum CRP in the multivariate linear regression model. In conclusion, better self-reported oral health, fewer missing teeth and higher interdental cleaning frequency were associated with lower serum CRP in US population.
