Type: article

Abstract: INTRODUCTION AND AIMS: Neutrophil percentage-to-albumin ratio (NPAR) is a novel biomarker of systemic inflammation. The aim of this study was to explore the relationship between NPAR and periodontitis. METHODS: Data from the National Health and Nutritional Examination Survey (NHANES) between 2009 and 2014 (N = 10,128) were utilized in this cross-sectional study. Periodontitis categories were defined according to the Centres for Disease Control and Prevention and American Academy of Periodontology (CDC/AAP) classification. The NPAR was calculated by dividing the neutrophil percentage by serum albumin. Covariates included age, sex, race, education level, annual household income, marital status, smoking status, BMI, recreational activity, work activity, diabetes mellitus, hypertension, and cardiovascular disease. Weighted logistic regression analysis was conducted to investigate the linkage between NPAR and moderate/severe periodontitis, and weighted linear regression analysis was performed to explore the relationship of NPAR with mean attachment loss (AL) and mean probing pocket depth (PPD). RESULTS: = 1.28, 95% CI: 1.10-1.49). These findings were consistent across different subgroups analysed. Furthermore, our study demonstrated that NPAR was also positively correlated with mean AL and PPD, which are key indicators of periodontal health. CONCLUSIONS: Our results suggest that NPAR is significantly linked to poor periodontal health. However, owing to the cross-section design of this study, additional longitudinal studies are necessary to further enhance our comprehension of the impact of NPAR on periodontal status. CLINICAL RELEVANCE: Elevated neutrophil counts and low albumin levels correlate with moderate/severe periodontitis. Monitoring these markers may aid in assessing periodontitis risk.
