Older persons frequently have poor dental health, which can hinder vital daily activities and increase frailty. Using six distinct electronic databases, we conducted a systematic evaluation of publications on the connection between oral health variables and frailty in older persons. We looked for studies that had been published since the creation of the databases. Overall, met the eligibility conditions, including various markers of poor oral health related to frailty, which we categorised into four separate categories: degradation of oral motor skills, deterioration of oral health status, problems of chewing, swallowing, and saliva, and oral discomfort. The most common factors linking frailty to oral health status degradation were the few surviving teeth. reduced chewing, swallowing, and saliva production; oral diadochokinesis; occlusal force; and reduced oral motor skills, particularly masticatory function.
