Objectives To examine dental caries severity (measured by number of carious teeth) in older adults in the last year of life. Design Cross‐sectional study based on dental records. Setting Community‐based geriatric dental clinic. Participants One thousand two hundred sixteen individuals aged 65 and older, including 168 individuals in the last year of life (e.g., individuals died within 1 year after their new‐patient examinations). Measurements Information on socioeconomic, medical history, medication, functional status, and oral health measures, including number of carious teeth, was abstracted from dental records. End‐of‐life status was determined using the National Death Index. Propensities of death were calculated using a logistic regression and then adjusted together with mobility and oral care function in the multivariable regression model to examine the effect of end‐of‐life status on dental caries. Results Caries severity differed in end‐of‐life participants with different oral care function. Of those needing help with oral care, end‐of‐life participants had only a slightly higher and nonstatistically significant risk (7.5 vs 6.1, adjusted incidence density ratio ( IDR ) = 1.12, 95% confidence interval ( CI ) = 0.85–1.48) of having more carious teeth than those not in the last year of life. On the other hand, caries severity was lower in end‐of‐life participants without impaired oral care function ( IDR = 0.53, 95% CI = 0.30–0.92). Conclusion Oral care function modifies the association between caries severity and end‐of‐life status. Individuals who could maintain oral hygiene independently had a low level of caries at the end of life, however, dental caries had increased before functionally dependent individuals entered their last year of life.
