[Prenatal caries prophylaxis with fluoride tablets].

The attitude towards the use of fluoride tablets during pregnancy differs considerably: from absolute denying to assertion of obligate fluoride intake, even in higher doses than recommended. On the basis of our shides as well as of studies of other authors of pathohistologic, chemical and epidemiologic placental permeability of fluorides and of the influence of fluorides on the hard teeth tissues formed during the pregnancy, it can be concluded that: Fluoride application during pregnancy is a positive method since the effect of caries reduction in deciduous and permanent dentition has been confirmed; Tablets should be used from the 10the or 12the week of pregnancy; Tablets should be taken 30 minutes before the meal and an hour and a half before the intake of calcium tablets; The optimal daily dose for a pregnant woman is 1 mg of fluoride.
