Tooth loss, periodontal disease, and cognitive decline in the Atherosclerosis Risk in Communities (ARIC) study.

ABSTRACT:

Objective

The purpose of this prospective study was to investigate whether poor oral health predicted 8-year cognitive function change in predominantly late middle adults in the Atherosclerosis Risk in Communities (ARIC) study.

Methods

Participants included a subset of ARIC participants aged 52-75 years at 1996-1998 from two study sites: Forsyth County NC and Jackson MS. All subjects completed cognitive function assessments both in 1996-1998 and 2004-2006, and the same subjects received a dental examination at the initial visit.
