Oral health disparities in older adults: oral bacteria, inflammation, and aspiration pneumonia

Abstract

Poor oral hygiene has been suggested to be a risk factor for aspiration pneumonia in the institutionalized and disabled elderly. Control of oral biofilm formation in these populations reduces the numbers of potential respiratory pathogens in the oral secretions, which in turn reduces the risk for pneumonia. Together with other preventive measures, improved oral hygiene helps to control lower respiratory infections in frail elderly hospital and nursing home patients.
