Abstract: The purpose of this study was to investigate the relationship between diet quality and periodontal disease, in adults aged ≥40 years, using data from the 7th (2016–2018) Korea National Health and Nutrition Survey (KNHANES), representing South Koreans. The subjects of this study were 7935 people aged ≥40 years, who responded to the items in the Korea Healthy Eating Index (KHEI) and underwent periodontal examination. Complex sample univariate and multivariate logistic regression analyses were conducted, to analyze the relationship between the diet quality and periodontal disease. The group with a low diet quality for energy intake balance, showed a higher risk of periodontal disease than the group with a high diet quality for energy intake balance, and it was confirmed that the diet quality in adults aged ≥40 years was related to periodontal disease. Therefore, regular diet evaluations, and the counseling of gingivitis and periodontitis patients by dental experts, will have a positive effect on the restoration and improvement of periodontal health in adults.
