Outcome Measures

Primary Outcomes (1)

  • Number of Caries Incident Cases

    A trained, calibrated dentist blinded to treatment arm performed visual-tactile dental exams at 1 and 2 years post-baseline. Group-specific number of incident cases were reported as the number of individual participants with caries at a follow-up visit.

Limitations and Caveats

In a protocol deviation, children received placebo varnish for 10 months; this would be expected to bias the study toward the null of no difference among groups. The study did not address FV efficacy for children with extant or past caries.
