The Centers for Disease Control and Prevention (CDC) reports that preterm birth affected about 1 in 10 infants born in the United States in 2015. These statistics emphasize the significance of implementing a safe and effective therapy into routine clinical care aimed at reducing the rate of preterm birth. There has been evidence to suggest that fluoride supplementation to women during pregnancy can provide other medical benefits, in addition to a reduction in dental caries.
Fluoride is recognized by the Food and Nutrition Board (F&NB) of the American Academy of Sciences and the Food & Drug Administration (FDA) as an essential ion due to its association with a reduction in dental caries.
Upon entering the body, fluoride is taken up into the bones/calcified tissues, and excreted by the kidneys. When supplied during pregnancy in small aliquots, as with water fluoridation, the fluoride is likely taken up in the mother's bones and excreted by her kidneys so rapidly, that the fetus is denied a meaningful amount of fluoride, unless it is supplied in a pulse dose by supplement. The Institute of Medicine's Food and Nutrition Board recommends 3 mg/day for Adequate Intake in pregnancy and deems 10 mg/day as the Upper Limit.
After several papers elucidating an association between poor dentition, periodontal disease, and preterm birth, subsequent RCT's of regular periodontal scaling and treatment during pregnancy are still inconclusive in regards to preterm birth.
The investigators hypothesize that fluoride supplementation during pregnancy may have a beneficial effect on the natural microbiome of the maternal oral cavity and genital tract, capable of protecting against transient bacteremia and ascending infection, respectively, which are known antecedents to both preterm labor and preterm premature rupture of membranes. The research team predicts that the testing and analysis of specimens collected will demonstrate microbiome changes toward a more favorable profile not associated with preterm birth.
The proposed randomized, double-blinded, placebo-controlled clinical trial aims to confirm the efficacy of fluoride supplementation in pregnancy to extend length of gestation and increase overall perinatal well-being, and to confirm transplacental transfer of supplemental fluoride. This research may also identify other beneficial maternal and neonatal outcomes associated with the administration of fluoride during the perinatal period by attempting to characterize and compare the microbiomes of the maternal oral cavity and genital tracts between supplemented and unsupplemented gravidas.
