Abstract: Objective:To explore the relationship between Chronic Obstructive Pulmonary Disease (COPD) and periodontitis. Methods: 498 subjects were recruited in this study and were divided into three groups: mild periodontitis group (77, 15.5%), moderate periodontitis group (143, 28.7%), and severe periodontitis group (278, 55.8%). Clinical examination indexes included probing depth (PD), attachment loss (AL), sulcus bleeding index (SBI), plaque index (PLI) and the level of the alveolar resorption. Lung function of each subjects were also examined. Results: The levels of AL, PLI and alveolar resorption in COPD group were higher than non-COPD group. Significant differences of "FEV1% pre"(F=3.59,P=0.028) and "FEV1/FVC"(F=4.84,P=0.008) were found among different degrees of periodontitis. Negative relationship was found between the level of "FEV1% pre" and the periodontal index (AL, PLI, alveolar resorption), and the same relationship was found for "FEV1/FVC". Conclusion: Correlation is found between COPD and the periodontitis index (AL, PLI, alveolar resorption).
