Note: All estimates are adjusted by age (single years) to the US 2000 standard population. SE = standard error. FPL = federal poverty level; <100% FPL = poor; 100%–199% FPL = near-poor; <200% FPL = poor and near-poor combined; and ≥200% FPL = not-poor.

*P < 0.05 based on t-test for differences between two periods or two groups within each characteristic.

a Defined as having one or more untreated decayed or filled primary teeth among children with at least one primary tooth.
b Change in percentage points from 1999–2004 to 2011–2016. Positive value = increase; negative value = decrease.
c Reference group for comparisons within each characteristic, 2011–2016.
