Abstract
AbstractObjectiveThe aim of this study was to evaluate the association between the lack of a functional dentition and edentulism with mortality in a cohort of older adults in a Southern Brazilian city.Materials and MethodsThis is a longitudinal study carried out with community‐dwelling older adults (≥60 years old) from Pelotas, Brazil, using data from the baseline (2014) and the first follow‐up (2017). Main exposures were functional dentition (20+ teeth present) and edentulism (absence of all teeth), derived from self‐reported number of teeth. All‐causes mortality was evaluated according to the city's Epidemiological Surveillance Department. Potential confounders were age, sex, socioeconomic position, smoking, diabetes, hypertension, and body mass index (BMI). To test the association between functional dentition and edentulism with mortality, Poisson regression models with robust variance were used, to estimate Relative Risks and 95% confidence intervals.ResultsA total of 1289 older adults had information on all variables of interest and comprise the analytical sample (from 1451 at baseline). When analysing the presence of functional dentition, only 222 individuals (17.2%) had 20 or more teeth in their mouth, while 490 older adults were edentulous (38.0%). Crude analysis showed an association between tooth loss indicators and mortality. Models adjusted for sociodemographic variables and health conditions and behaviours revelled no association between the exposures and mortality.ConclusionsWith the findings of this study, we did not identify an association between edentulism and functional dentition with mortality, after considering important shared risk factors.
