Outcome Measures

Primary Outcomes (1)

  • Change in the Number of Decayed or Filled Permanent Teeth (DFT) From Baseline (Beginning of Kindergarten) to the Middle of 2nd Grade

    The primary outcome measure was change in the number of decayed or filled permanent teeth (DFT). Caries was assessed in accordance to the International Caries Detection and Assessment System (ICDAS). The ICDAS criteria record both the severity and activity of the lesion on occlusal surfaces, in pit and fissure sites on the buccal and lingual surfaces, and on other smooth surfaces. For the purposes of this study, an ICDAS severity score of 3 to 6 and the presence of fillings constituted the "D" and "F" portions of DFT, respectively.

Limitations and Caveats

Nearly half the children moved out of the school district by the time of the exit examination, which made the power of the analysis insufficient to detect the difference between two groups.
