Associations Between Periodontitis and Chronic Obstructive Pulmonary Disease: The 2010 to 2012 Korean National Health and Nutrition Examination Survey.
2016
Background: The aim of this study is to examine whether oral hygiene and self-care, particularly in periodontal health, are associated with chronic obstructive pulmonary disease (COPD) in the Korean population.Methods: Data from the Korean National Health and Nutrition Examination Survey from 2010 to 2012 were used to assess the community periodontal index (CPI) of 5,878 participants (normal lung function: n = 5,181; obstructive spirometric pattern: n = 697) aged ≥40 years, who underwent spirometry.Results: Participants with COPD brushed their teeth less frequently and used the following less frequently: 1) dental floss and/or interdental brush; 2) mouthwash; and 3) electric toothbrush (P <0.001). Prevalence of periodontitis in patients with COPD (58.1%) was significantly higher than in those without COPD (34.0%, P <0.001). Number of teeth was significantly lower in patients with COPD compared with controls. Decayed-missing-filled tooth index was significantly lower in patients with COPD. This study shows...
