Maslak et al. (23) in a three year study,
investigated the effect of fluoridated milk in children
who were caries-free at 3 years of age. In this doubleblind
evaluation, undertaken by examiners
calibrated according to WHO criteria, on 75 test
and 91 control children, they found statistically
significant reductions both in dmft and DMFT
values, in longitudinal, as well as in cross-sectional
comparative analyses.
