A t-test was used to determine whether changes in sealant use and decay prevalences between surveys or mean DFFM by sealant status and income were significant.
Among children aged 7-11 years, the mean DFFM was significantly lower for both higher-income and low-income children with at least one sealant (0.19 and 0.29, respectively) compared with children with no sealants (0.52 and 0.82, respectively) (Table 3).
The estimated average annual probability of a permanent first molar developing decay, calculated with DFFM data by year of age for children aged 7-11 years, was 0.07 for lowincome children (data not shown).
Because NHANES is not designed to provide estimates by year of age, a large number of estimates of DFFM by year of age and sealant status were unstable.
Substituting the appropriate values in equation 1 and solving for dFFM results in a dFFM of 1.0971705 g/[cm.sup.3], as opposed to 1.1 g/[cm.sup.3] before the fluid load.
