Unmasking the Silent Threat: Periodontal Health's Impact on COPD Severity and Hospitalization.

Periodontal Severity and COPD Exacerbations Figure 2 shows the association between lung function parameters (post-bronchodilator FEV 1 percent predicted, FVC percent predicted, and FEV 1 /FVC ratio) and periodontitis severity, which showed that an increase in periodontitis severity and lung functions followed a decreasing trend even after adjusting for smoking (in pack-years), which was statistically significant ( p < 0.001).

However, exercise tolerance, measured by the six-minute walk distance, did not reach statistical significance ( p = 0.0641) between different GOLD groups.

Furthermore, a clear trend emerged when assessing the relationship between the mean levels of these indices and the number of exacerbations within the past year.
