Introduction: Periodontitis is a chronic inflammatory disease associated with a number of lung conditions such as chronic obstructive pulmonary disease (COPD) and pneumonia. Both chronic periodontitis (CP) and COPD share similar risk factor profiles. Thus, recognition of interaction between periodontitis and COPD could lead to establishment of better preventive and therapeutic approaches. The microbial analysis of sputum from COPD patients with CP to detect periodontal pathogen Porphyromonas gingivalis (P. gingivalis) both before and after nonsurgical periodontal therapy. Materials and Methods: The study group comprised 30 individuals diagnosed as COPD with CP. Periodontal indices, lung function test, and P. gingivalis in sputum were assessed before and 6 months after nonsurgical periodontal therapy. Results: A decrease in the count of P. gingivalis and decreased periodontal indices values were observed in COPD patients with periodontitis after nonsurgical periodontal therapy. Lung function test (forced expiratory volume in the first/forced vital capacity) was improved in COPD patients with periodontitis after nonsurgical periodontal therapy. Conclusions: The study results suggest that nonsurgical periodontal therapy can be a part of treatment protocol in COPD patients because it helps in reducing the P. gingivalis count and improving the lung function.
