Xerogenic Medications as a Predictor for Dental Health Intervention in People with Dementia

• Background: Older adults with dementia often have poor oral health. Chronic use of xerogenic medications may contribute to adverse dental outcomes.Objective: To investigate the impact of xerogenic medication classes on the predicted risk for dental interventions in people with dementia.Methods: Thiswas a population-based cohort study involving 30,955 individuals registered in the Swedish Dementia Registry (SveDem) from 2008 to 2015. Data were linked with other national registers. The exposure was xerogenic medication classes used in the three years prior to dementia diagnosis (baseline). The primary outcome was the composite of number of tooth extractions and dental restorations over the three-year follow-up period. Secondary outcomes included the number of tooth extractions and number of dental restorations. Poisson regression models were used to estimate the association between the exposure and outcomes. Analyses were adjusted for age, gender, Mini-Mental State Examination, living arrangement, dementia disorder, average number of medications, Charlson’s comorbidity index, number of dental visits, and number of teeth.Results: After adjusting for potential covariates, the use of urological drugs (incidence rate ratio [IRR] 1.16, 95% CI 1.04–1.28), proton pump inhibitors (IRR 1.13, 95% CI 1.04–1.23), and opioids (IRR 1.19, 95% CI 1.06–1.34) were significantly associated with the primary composite outcome.Conclusion: The use of specific classes of xerogenic medications was associated with an increased risk for tooth extractions and restorations in people with dementia. The risks and benefits of xerogenic medications, in the context of oral health, should be carefully assessed in this vulnerable population.
