Periodontal disease and risk of chronic obstructive pulmonary disease: a meta-analysis of observational studies.

<h4>Background</h4>Many epidemiological studies have found a positive association between periodontal disease (PD) and risk of chronic obstructive pulmonary disease (COPD), but this association is varied and even contradictory among studies. We performed a meta-analysis to ascertain the...
