Association between probiotic consumption and periodontitis: Evidence from NHANES 2009–2014

Abstract

Aim: The study aimed to provide evidence of the relationship between probiotics consumption and periodontitis. Materials and Methods: A total of 4577 adults who participated in the National Health and Nutrition Examination Survey (NHANES) during 2009–2014 were included in the study. The weighted prevalence of periodontitis was compared among different groups, and a weighted binary logistic regression analysis was conducted to explore the relationship between probiotic consumption and periodontitis. Receiver operating characteristic (ROC) curves were used to assess the role of probiotic consumption in the periodontitis prediction model. Results: Participants who consumed probiotics had a significantly lower prevalence of periodontitis than those who did not (41.08% vs. 27.83%, p
