“As the numbers of people with Alzheimer’s disease and other cognitive disabilities increase, scientists are investigating how these conditions may be related to oral health. After evaluating available research, the International and American Associations for Dental Research concluded that individuals with fewer than 20 teeth face a 26% greater risk of cognitive decline and 22% greater risk of dementia.
The researchers searched the MEDLINE, EMBASE, PsycoINFO, and Cochrane Library databases and identified 1,251 articles published between 1990 and 2014, choosing 10 for their systematic review and 8 for their meta-analysis. A pair of researchers reviewed and assessed the studies independently according to Strengthening the Reporting of Observational Studies in Epidemiology guidelines.”
