Research progress on the relationship between cognitive impairment and oral health

Abstract

With the intensification of the aging of population, the number of patients with neurodegenerative diseases such as cognitive impairment is increasing. Patients with cognitive impairment often have poor oral health, which previous studies have suggested that may be related to poor oral hygiene habits. However, studies in recent years have shown that oral diseases may accelerate the development of cognitive impairment through infections and other routes. In this article, the correlation and possible mechanisms of oral health including periodontitis, masticatory function, and oral mucosal disease and cognitive impairment will be elaborated.
