One of the most extensive milk
fluoridation programs, which is still functioning,
was initiated by Pakhomov et al. (16) in Bulgaria in
1988 with the support of WHO. The objective was
to see if such a program was feasable under everyday
life conditions. Bulgaria seemed to be an excellent
choice for this community-based program due to
the regular consumption of milk and milk products
(for example, yoghurt) by children.
