Association between dietary antioxidant quality score and periodontitis: A cross-sectional study.

ABSTRACT:

Background/purpose

Evidence to date linking relation between dietary antioxidant quality score (DAQS) and periodontitis is limited. This study aimed to investigate the relationship between DAQS and periodontitis.

Materials and methods

In total, 9457 participants from the National Health and Nutrition Examination Survey 2009-2014 were enrolled in this cross-sectional study. The outcome was defined as periodontitis. DAQS was calculated by comparing the daily dietary intake of six micronutrients (vitamin A, C, E, selenium, magnesium and zinc) to the recommended daily intake, which was divided into three groups: low quality (1-2 points), medium quality (3-4 points) and high quality (5-6 points). Weighted logistic regression models were carried out to examine the association of D
