Mediation of Systemic Inflammation and Oxidative Stress Markers in the Association of Life's Crucial 9 with Periodontitis: Evidence from NHANES 2009-2014.

LC9 was linearly and negatively associated with the odds of periodontitis; systemic inflammation and oxidative stress markers may partially explain this association. These findings suggest that LC9 may serve as a valuable, comprehensive tool for assessing the likelihood of developing periodontitis, emphasizing that improving overall cardiovascular and mental health may be associated with lower prevalence of periodontitis.
