^a Denotes the mean number of decayed, missing, and filled teeth; ^b Denotes the mean number of decayed, missing and filled tooth surfaces; ^c Denotes the mean number of decayed, missing, and filled teeth on the pit-and-fissure surfaces; ^d Denotes the mean number of decayed, missing, and filled tooth surfaces on the smooth surfaces; * Indicates estimated marginal means; ^† Calculated using independent sample t-test between the non-CWF area and CWF areas after adjusting for sex, monthly family income, householder educational level, Family Affluence Scale score, and number of sealed teeth.
