Note: All estimates are adjusted by age (single years) to U.S. 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.

Defined as having one or more untreated decayed primary teeth among children with at least one primary tooth.
Change in percentage points from 1999–2004. Positive value=increase and negative value=decrease.
