Relationship between Periodontal Status and Chronic Obstructive Pulmonary Disease: A Cross-Sectional Study

Since Oral cavity is considered the main source of pulmonary pathogens and Chronic Obstructive Pulmonary Disease (COPD) is one of the most prevalent diseases and one of the most important causes of mortality, aim of this study was to determine the relation between periodontal status and COPD.Materials &

This Cross-Sectional study was performed in April to September 2018 on 30 patients with COPD as a case group and 30 respiratory healthy person as control group. In both groups, periodontal indices such as Gingival Recession(R), Probing Depth (PD), plaque Index (PI), Gingival Index (GI),Clinical Attachment loss (CAL) and Bleeding on Probing (BOP) were evaluated. The number of Missing Teeth (MT) was also recorded. Data were analyzed by the use of SPSS 22 with t-test, Chi-square, and Mann-Whitney statistical tests (α = 0.05).

Periodontal indices and MT in the COPD group were significantly more than control (p value < 0.001). The mean of smoking in COPD group was higher than control group T, but after neutralization of the effect of smoking, the mean periodontal indices in the COPDgroup was still more than control, also in non-smokers of COPD group, mean periodontal indices are more than non-smokers of control and the periodontal status was significantly associated with an increase in the grade of COPD (p value < 0.001).

This study showed periodontal diseases have considerable correlation with COPD and patients with COPD even after the control of cigarette smoking and oral hygiene as confounder factors, show worse periodontal conditions.
