“…Furthermore, periodontal disease exposure in earlier studies has been assessed with measures, such as the community periodontal index (CPI), which are based on clinical signs that do not provide much information about the underlying biology of periodontal disease (7). …”

Objective The purpose of this prospective study was to investigate whether poor oral health predicted eight-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. Cognitive assessment consisted of Delayed Word Recall (DWR), Digit Symbol Substitution (DSS), and Word Fluency (WF) tests. In the analysis, cognitive function for 911 dentally screened participants was evaluated, and 558 of 785 dentate participants received comprehensive oral examinations, including periodontal probing. Measures of oral health included dental status, number of teeth, and periodontal disease classified by the Biofilm-Gingival Interface (BGI) index. The generalized estimating equations (GEE) method was used to analyze repeated measures of cognitive scores with adjustment for socio-demographic characteristics and cardiovascular risk factors. Results Of 911 study participants, 13.8% were edentulous. About 13 % of dentally examined participants had periodontal pockets (≥4 mm) with severe bleeding. At the follow-up visit, DWR and WF scores were lower in edentulous compared to dentate people, whereas other oral health measures were not associated with cognitive function. Mean values declined over time for all three cognitive measures, although poor oral health conditions were not associated with greater degree of decline in cognitive function. Conclusions In these late-middle aged adults, complete tooth loss was significantly associated with lower cognitive performance. However, neither edentulism, number of teeth, nor periodontal disease predicted greater subsequent cognitive decline.

“…When severe, such impairments can lead directly to malnutrition, impacting the prognosis and increasing the burden on caregivers [67,68]. Also, factors such as declines in awareness and behaviors related to oral hygiene, difficulty in carrying out oral care and eating soft food due to declines in eating and swallowing functions clearly increase the risk of periodontal disease [69] (shown schematically in Fig. 1).…”

This study reviews the research of dementia, a pathology for which numerous studies have found associations with masticatory function in the elderly. These issues are presently major problems in geriatric medical and welfare settings, and we discuss the prospects for future research into mastication. Dementia and masticatory function have been examined in a range of epidemiological and neuroscientific studies, and associations between the two have been reported. However, a causal relationship has not been satisfactorily established. Biochemical studies have also clarified the basis of the association between dementia and periodontal disease, but have not yet yielded sufficient evidence. Studies offering a high level of evidence, such as intervention studies and meta-analyses, are expected to be undertaken in this area in the future. Maintenance and recovery of masticatory function is of great importance with respect to achieving healthy longevity. Dental science will have considerable obligations and will have to take on an important role in this regard. For dental treatment to take on such important roles in the fields of health, medicine and welfare, it is necessary to provide information that will be understood not just by other medical and healthcare professionals, but also by the general public.

“…These researchers recommended further studies in this field. In a study, no relationship was observed between oral hygiene and cognitive decline in geriatrics (7). Although some studies were conducted to assess oral health in the elderly, in our country, currently, there is insufficient evidence to develop recommendations for strategies to improve cognitive status among the elderly.…”

“…The results from some recent studies indicate a mild to moderate relationship between oral health as well as cognitive disorders (5). The reaction of the immune system to oral and dental bacteria seems resulted in the death of nerve cells or attenuation of memory (6,7). According to some studies, reduced number of teeth is associated with increased incidence of cognitive decline (5,8).…”

Background: Oral health has a major role in the health as well as quality of life of older adults. Objectives: The present study was conducted with the aim to determine the relationship between oral health and cognitive status of the elderly. Methods: In this descriptive, correlation, cross sectional study, 206 older individuals were selected according to a stratified random sampling method from health centers in Ghaemshahr, Iran between May and October 2016. Data collection tools included cognitive state test (COST), geriatric oral health assessment index (GOHAI), geriatric depression scale, as well as a socio-demographic questionnaire. Dental history and risk factors for cardiovascular diseases were also recorded. Data were analyzed using a logistic regression test.

Oral health condition of French elderly and risk of dementia: a longitudinal cohort study

Abstract: Having eleven or more missing teeth seemed to be associated with a lower risk of dementia in people with lower education possibly owing to the suppression of source of chronic inflammation.
