Abstract

Background: Clinical studies have suggested that lipids increase activity of white blood cells. The objective of this study is to examine whether high serum total cholesterol (STC) is associated with periodontitis. Methods: A total of 1,061 participants from the 2011 to 2012 National Health and Nutrition Examination Survey who underwent both periodontal examination and laboratory test for STC was included. To examine effects of high STC on periodontitis, odds ratios were calculated, adjusting for age, sex, education, income, smoking status, diabetes, body mass index, and calcium levels. Results: Statistically significant associations were observed between borderline as well as high STC and periodontitis. Study participants with STC between 200 and 239 mg/dL (borderline) were 1.67 times (95% confidence interval [CI]: 1.13 to 2.47) as likely to have periodontitis as those with normal levels (199 mg/dL), and those with STC 240 mg/dL (high) were 2.22 times (95% CI: 1.27 to 3.87) as likely to have periodontitis as those with normal levels. Conclusions: Positive significant association was observed between STC and periodontitis. Results of the present study provide insight into potential risk factors for periodontitis. High STC levels could be a potential risk factor for the disease; however, further studies need to be conducted to understand the actual relationship between STC levels and periodontitis and to establish causality and directional association.
