Association between oral health and incidence of pneumonia: a population-based cohort study from Korea

Abstract Pneumonia is related to oral health of the elderly and intensive care unit patients. However, studies on the relationship between overall oral health and pneumonia in the general population have been limited. The purpose of this study was to investigate the association between oral health a...

However, studies on the relationship between overall oral health and pneumonia in the general population have been limited. The purpose of this study was to investigate the association between oral health and pneumonia using a nationwide population-based Korean cohort database.

Cox proportional hazard regression analysis was performed to evaluate the association between oral health and pneumonia.
