  1. Odds ratios (OR) and 95% confidence intervals (95% CI) were derived from ordinal logistic regression and betas and 95% CI from linear regression analyses. Models were adjusted for gender, age, education
  2. Oral pain or discomfort (no, sometimes, yes), time period since last visit to an oral health care provider (< 1 year, 1–5 years, 5–10 years and > 10 years), chewing ability (good, rather good, poor, not able) and xerostomia scores (score 5, 6, 7, 8, 9 and > 10) were entered as ordinal independent variables in the ordinal logistic regression models. Cognitive functioning (MMSE score) and number of prescription medication categories were entered as continuous independent variables in the linear regression models. ADL = Activities of daily living. MMSE = Mini-Mental State Examination
