Background:
The present study investigated the relationship between certain periodontal variables and severity of disease in COPD patients.
Methods:
The present cross-sectional study included 50 patients suffering from COPD. Lung function examination, forced expiratory volume in one second (FEV1), forced vital capacity (FVC), FEV1/FVC, SpO2, and Modified Medical Research Council (MMRC) Dyspnea Scale were performed. Periodontal clinical examination index included probing depth (PD), attachment loss (AL), gingival index (GI) and plaque index (PI). A quality of life validated index, the COPD assessment test (CAT index), was also calculated.
Results:
The FEV1 and FVC indices showed a significant negative correlation with PI and AL variables only. The COPD assessment test (CAT) index showed a significant but positive correlation with PI and AL variables only. The SpO2 index presented a significant negative correlation with GI and AL variables. The FEV1/FVC ratio was found to have a negative correlation with PD and AL variables. It is worth noting that MMRC exhibited no significant relationship with any of the periodontal variables. The only variable that was significantly different (P=0.022) among the three smoking groups was the FVC index. The FVC value was significantly higher in the group of subjects who smoked more than 10 cigarettes per day versus the non-smoking group (P=0.017).
Conclusion:
Based on the findings of this study, in view of the relationship between periodontal variables and respiratory indices in the course of COPD, early treatment of periodontal diseases, might considerably reduce the severity of COPD.

Smoking is a primary risk factor for COPD, with over 80% of patients having a history of it. Patients typically experience progressive dyspnea or labored breathing, frequent coughing, and recurrent pulmonary infections. Many eventually succumb to respiratory failure, characterized by...

Symptoms of COPD can be classified as primary or systemic. Primary symptoms relate to reduced airflow, while systemic or extrapulmonary symptoms relate to COPD's broader impact on the body.
