title: [Preliminary study on transplacental transfer of fluoride. Apropos of 41 mother-infant couples].
abstract: Comparing the levels of ionised fluoride in the serum of maternal blood at the time of delivery and cord blood shows that there is a good correlation between the two levels (r = 0.66). This makes it possible to say that fluoride is transferred easily across the placenta. The transfer is not influenced by the parity of the age of the mother nor by epidural anaesthesia, nor by the Apgar score. It does, however, correlate with the duration of the pregnancy.
