title: [Relationship between bone fluoride content, pathological change in bone of aborted fetuses and maternal fluoride level].
abstract: Relationship between bone fluoride content, pathological change in bone of aborted fetuses and maternal fluoride level was studied in 46 pregnant women and their inducedly-aborted fetuses. Results showed fluoride content in fetal femur averaged 368.2 micrograms/g, and 41.4% of the bone with pathological change. Fluoride levels in maternal urine and amniotic fluid and fluoride content in fetal femur and pathological change in fetal femur appeared a positive correlation between them. Femur fluoride content and pathological change of bone in fetuses born to mothers with mottling teeth were significantly greater than to those without them. Pathological change in fetal femur presented dose-response relationship with their bone fluoride content. When the latter reached greater than 500 micrograms/g, pathological changes occurred in 90% of the bone.
