OBJECTIVES: This study investigated the association between bone mineral density (BMD) and periodontitis in a representative sample of Korean adults. MATERIAL AND METHODS: Of 36 188 individuals who participated in the Korea National Health and Nutrition Examination Survey in 2008, 2009, and 2010, 9977 participants aged >= 40 years were included in this cross-sectional study. The associations of BMD of lumbar spine, total femur, and femoral neck with periodontitis were investigated using logistic regression analysis. Additionally, dose-response relationships with BMD divided into quintiles and the association between osteoporosis and periodontitis were investigated. RESULTS: With the set of Community Periodontal Index (CPI) >= 3 as a dependent variable, logistic regression analysis revealed that a decrease of BMD was significantly associated with higher odds of periodontitis [range of adjusted odds ratios (AORs); 1.15-1.20, P < 0.001 for all BMD sites]. Similarly, these associations were also found in the CPI 4 model. With regard to dose-response relations, the lower the BMD quintile, the higher the AORs appeared with statistical significance in the CPI >= 3 model. (P for trend < 0.001) Participants with osteoporosis had 2.26 and 1.91 times higher odds for CPI >= 3 and CPI 4, respectively, than those with normal BMD, indicating a significant association between the two diseases. CONCLUSIONS: Our results suggest that BMD is significantly associated with periodontitis.
