Abstract
Aim: To investigate the within- and between-person longitudinal effects of tooth loss and the use of dentures, clinically assessed by dentists, on cognitive decline in a representative sample of community-dwelling older Brazilian adults. Methods: Data came from 1265, 1112 and 1021 individuals aged ≥60 years who participated in the second (2006), third (2010) and fourth (2015) waves, respectively, of the Health, Well-being and Aging study (SABE). Cognitive performance was evaluated with the abbreviated version of the Mini-Mental State Examination (MMSE). The number of natural teeth was classified according to three categories: none, 1–19 and ≥20 teeth. The presence of removable full or partial dentures in each dental arch (yes/no) was recorded. Hybrid regression models, adjusted for sociodemographic, behavior and health-related covariates, were used to estimate the between- and within-person effects of the longitudinal association between cognitive performance and oral health. Results: Participants with 1–19 and no teeth had, respectively, 1.15 (95% CI 0.65–1.66) and 1.54 (95% CI 0.99–2.09) units lower MMSE score than those with ≥20 teeth. Denture wearers had 1.54 (95% CI 1.13–1.95) units greater MMSE score than non-denture wearers, and those who started wearing dentures during the follow up had 0.83 (95% CI 0.21–1.45) units greater MMSE score after the transition. Conclusion: Our main findings showed that the use of dental prostheses might be a protective factor for cognitive decline. Geriatr Gerontol Int 2021; 21: 1093–1098.
