Percentage Point Difference between Changes in Disparities for Untreated Caries Prevalence and Past-Year Dental Use by Income (Household Income <200% Federal Poverty Level [FPL] or Household Income ≥200% FPL) between 1999–2004 and 2011–2016, National Health and Nutrition Examination Survey and Medical Expenditure Survey.

DU, past-year dental use; UC, untreated caries prevalence.
