Abstract

Vitamin C, rich in fruits, has long been a candidate for preventing periodontal disease due to its effects on extracellular matrix and inflammatory reactions. Therefore, this study is to evaluate the relationship of fruit intakes (the main dietary source of vitamin C) and dietary vitamin C, with risk for generalized periodontitis using the 2007-2010 Korean National Health and Nutrition Examination Surveys. A total of 1,690 adults (≥ 40 years of age), with results of dental examination including all sextant information of probing depth at two index teeth, nutritional assessment, and demographic and medical information) were included in the studies. Dietary fruit and vitamin C intakes were estimated by a single 24-hour dietary recall. Individuals with periodontitis were defined as those who had 3-4 points of Community Periodontal Index (CPI) at all locations of 6 examination sites with a probe. Using multiple logistic regression analysis, we found a relationship between increased dietary fruit intake (P-trend= 0.0020) and vitamin C (P-trend =0.0325) consumption, and decreased risk for periodontitis for males. Adequate intake of fruits and vitamin C is recommended for prevention of periodontal diseases for the Korean population.
