This study investigated the association between tooth loss and cognitive decline in a group of older adults from Ireland. The findings suggest that tooth loss and the loss of occluding tooth pairs may be risk indicators for low cognitive function.
Objectives: To investigate whether tooth loss and related loss of occluding tooth pairs, were associated with cognitive decline in a group of community dwelling older men and women from Ireland. Methods: A group of 2508 men and women, aged 50-93 years, underwent a dental examination as part of The Irish Longitudinal Study of ageing (TILDA). Global cognitive function was assessed using the mini-mental state examination (MMSE). Analysis included multiple logistic regression with adjustment for various confounders. Results: The mean age of participants was 65.5 years (SD 8.1) and 55.3% of the group were female. Three hundred and twenty-nine (13.1%) of the cohort were classified as having a low MMSE with a score <= 27. After adjustment for confounding variables, compared to subjects with > 20 teeth, the odds ratio for a low MMSE amongst edentulous was 1.55 (95% CI 1.03-2.34) p = 0.03, and for those with 1-19 teeth was 1.38 (95% CI 1.03-1.84) p = 0.04. Having < 10 natural occluding pairs and < 4 posterior occluding pairs also associated with a low MMSE. Conclusions: In this cross-sectional cohort study, tooth loss and related loss of occluding tooth pairs were associated with a low MMSE in a group of older adults from Ireland, independent of various known confounders. Clinical Significance: Dentists should be aware of the potential systemic health implications of patients presenting with tooth loss. Tooth loss may be an important risk indicator for cognitive decline.
