Associations between oral frailty, oral microbiota composition, and postoperative delirium in older adult patients

Poor oral health, prevalent among the older adults, can undermine overall health and contribute to frailty. Older adults experiencing oral frailty and dysbiosis potentially face an elevated risk of postoperative delirium. This study aims to explore the influence of oral frailty and changes in oral microbiota composition on occurrence of postoperative delirium in older adult patients undergoing non-cardiac surgery.
