Abstract
ObjectiveThe purpose of this case‐control study was to determine the association between dementia and the number of missing teeth, functional occlusal units and denture use in older adults residing in Long‐Term Care (LTC) facilities.BackgroundMany studies have shown an association between dementia and tooth loss. However, few studies with a large sample size have been reported describing the relationship between dementia and the number of missing teeth, remaining teeth and functional occlusal units.MethodsAn oral health assessment database of 2160 older adults admitted to LTC facilities in Vancouver, Canada, between 2015–2019 was utilised. Participants with a diagnosis of dementia in their medical records (N = 1174) were compared to those without dementia (N = 986). Multiple logistic regression analysis was used to explore a potential association between the number of missing teeth, functional occlusal units and the use of dentures and dementia.ResultsThe number of remaining teeth (OR = 1.0, 95% Confidence Interval = 1.0–1.0; P = .054) and number of functional occlusal units (OR = 1.0, 95% CI = 1.0–1.0; P = .059) were not associated with dementia after adjusting for age, sex, oral self‐care and systemic conditions. Denture use (OR = 1.1, 95% CI = 0.5–2.4; P = .790) was not associated with dementia in edentulous patients.ConclusionThere was no association between dementia and the number of remaining teeth, functional occlusal units or wearing dentures.
