Small-angle X-ray diffraction analysis of the effect of fluoride on human bone apatite

摘要: Abstract Small-angle X-ray diffraction studies were performed on a series of human rib samples containing varying amounts fluoride. The results show that rise in fluoride content was accompanied by decrease the area interface between mineral apatite phase and remaining bone tissue. Detailed analysis suggest this can only be accomplished an increase mean volume concomitant number crystallites. Further considerations improvement “crystallinity” as measured wide-angle diffraction, reported previous publications, accounted for entirely crystallite size. Apparently these progressive changes tolerated individual without producing significant physiological consequences.
