To study the associations of instrumental activities of daily living (IADL) and the handgrip strength with oral self-care among dentate home-dwelling elderly people in Finland.
The study analysed data for 168 dentate participants (mean age 80.6 years) in the population-based Geriatric Multidisciplinary Strategy for Good Care of the Elderly (GeMS) study. Each participant received a clinical oral examination and structured interview in 2004-2005. Functional status was assessed using the IADL scale and handgrip strength was measured using handheld dynamometry.
Study participants with high IADL (scores 7-8) had odds ratios (ORs) for brushing their teeth at least twice a day of 2.7 [95% confidence intervals (CI) 1.1-6.8], for using toothpaste at least twice a day of 2.0 (CI 0.8-5.2) and for having good oral hygiene of 2.8 (CI 1.0-8.3) when compared with participants with low IADL (scores =6). Participants in the upper tertiles of the handgrip strength had ORs for brushing the teeth at least twice a day of 0.9 (CI 0.4-1.9), for using the toothpaste at least twice a day of 0.9 (CI 0.4-1.8) and for good oral hygiene of 1.1 (CI 0.5-2.4) in comparison with the study subjects in the lowest tertile of handgrip strength.
The results of this study suggest that the functional status, measured by means of the IADL scale, but not handgrip strength, is an important determinant of oral self-care among the home-dwelling elderly.
Gerodontology 2010; Dementia and oral health among subjects aged 75 years or older Objective: To study the association between diagnosed dementia and oral health, focusing on the type of dementia, among an elderly population aged 75 years or older. Background: Elderly people with dementia are at risk from oral diseases, but to date, only a few studies have analysed the association between type of dementia and oral health, and their results are inconclusive. Materials and methods: This cross-sectional study is based on the Geriatric multi-disciplinary strategy (Gems) study that included 76 demented and 278 non-demented subjects. The data were collected by means of an interview and an oral clinical examination. The type of dementia was diagnosed according to DSM-IV criteria. Poisson's and logistic regression models were used to determine relative risks (RR), odds ratios (OR) and 95% confidence limits (CI). Results: Our results showed that patients with Alzheimer's disease and those with other types of dementia had an increased likelihood of having carious teeth, teeth with deep periodontal pockets, and poor oral and denture hygiene, compared with non-demented persons. The results showed that the type of dementia does not seem to be an essential determinant of oral health. Conclusions: Among the elderly aged 75 years or older, patients with Alzheimer's disease or other types of dementia are at increased risk of poor oral health and poor oral hygiene.
