- Abstract
Aim: To investigate the medium‐term associations of serum protein subfractions derived from proton nuclear magnetic resonance (1H‐NMR) spectroscopy with periodontitis and tooth loss. Materials and Methods: A total of 3031 participants of the cohort Study of Health in Pomerania (SHIP‐TREND) were included. In addition to conventional serum testing, serum lipoprotein contents and subfractions were analysed by 1H‐NMR spectroscopy. Confounder‐adjusted associations of lipoprotein variables with periodontitis and the number of missing teeth variables were analysed using mixed‐effects models with random intercepts for time across individuals, accounting for multiple testing. Results: While only spurious associations between lipoprotein levels from conventional blood tests were found—that is, triglycerides were associated with mean clinical attachment level (CAL) and low‐density lipoprotein cholesterol/high‐density lipoprotein cholesterol (LDL‐C/HDL‐C) ratio with the number of missing teeth ‐ several associations emerged from serum lipoprotein subfractions derived from 1H‐NMR analysis. Specifically, elevated LDL triglycerides were associated with higher levels of mean probing depth (PD), mean CALs, and increased odds of having <20 teeth. HDL‐4 cholesterol levels were inversely associated with mean PD. Systemic inflammation (C‐reactive protein) might mediate the effects of LDL and HDL triglyceride contents on periodontitis severity. Conclusions: Several associations between serum lipoprotein subfractions and periodontitis were observed. As the underlying biochemical mechanisms remain unclear, further research is needed.
