Objective: The purpose was to evaluate the association between bite instability and comorbidities, comprehensive geriatric evaluations, or disabilities in elderly people.
Methods: A dentist examined the oral function, such as the bite stability, number of teeth, and the use of dentures, in 119 patients (93 women, mean age: 86.7±7.8) in 2 nursing homes for the elderly. The association between the oral function and the prevalence of diseases, including hypertension, diabetes mellitus, and dementia, was analyzed.
Results: The median number of teeth was 0 [0,4]. The patients were divided into a bite-stable group (n=78, 66%) and bite-unstable group (n=41, 34%). The prevalence of hypertension was significantly higher in the bite-stable group than in the bite-unstable group (83% vs. 63%, respectively; p=0.0149), whereas the prevalence of diabetes mellitus was significantly lower in the bite-stable group than in the bite-unstable group (10% vs. 27%, respectively; p=0.0190). The prevalence of a cognitive function decline was significantly lower in the bite-stable group as well (59% vs. 83%, p=0.0082). According to the simplified comprehensive geriatric assessment 7, the bite-stable group scored significantly higher for instrumental activities of daily living (ADL) than the bite-unstable group (54% vs. 24%, respectively; p=0.0021). A multivariate logistic regression analysis demonstrated that bite instability was in dependently correlated with hypertension, diabetes mellitus, and instrumental activities of daily living.
Conclusion: Bite instability was independently associated with a decreased prevalence of hypertension or increased prevalence of diabetes mellitus and low levels of instrumental ADL in the elderly.
