Background: The relationship between oral health and systemic conditions has been increasingly debated over recent decades with one such discussion existing about oral hygiene and periodontitis with chronic obstructive pulmonary disease (COPD). Hence, a study was conducted to assess and compare the oral hygiene status and periodontal status of age and gender-matched participants with and without COPD and to correlate oral hygiene status and periodontal status with lung function status among them. Materials and Methods: This hospital-based study included a study population of 117 participants (39 patients of COPD and 78 participants without COPD) 35–75 years of age with at least 20 natural teeth. Participant's demographic details and history of smoking were recorded. Lung function was recorded using a spirometer. Periodontal health was assessed by measuring Probing Pocket Depth (PPD), Clinical Attachment Loss (CAL), and Oral Hygiene Index (OHI) by a trained and calibrated examiner. Results: Higher mean of PPD, CAL, and OHI is being reported in the present study with 4.07 versus 3.50, 0.58 versus 0.24, and 5.24 versus 3.60, respectively, among patients with and without COPD which was statistically significant. The risk of having COPD was 0.4 times more in participants having poor oral hygiene and 0.07 times more in patients smoking. Smoking and oral hygiene, as independent variables, have a significant influence on COPD which is a dependent variable. A weak correlation was found of poor oral hygiene and loss of attachment among participants with COPD. Conclusion: Periodontitis and respiratory disease share a common risk factor, i.e., smoking. Smoking has a definite relation with periodontitis and COPD. Oral hygiene is significantly associated with increased risk for COPD when age and gender effects have been matched and when adjusted for smoking. However, no association was found of PPD with COPD.
