A. Scanning electron microscopic graph and XRD spectrum of enamel surface demineralised with 37% ortophosphoric acid and brushed in vitro 2 times (1 min) a day for 15 days without any past application. Pits obtained by chemical attack and disruption by mechanical wear may be observed. Original magnification 5000X Bar=10μm.
B. Scanning electron microscopic graph and XRD spectrum of enamel surface demineralised with 37% ortophosphoric acid
and brushed in vitro 2 times (1 min) a day for 15 days with fluoridated toothpastes. Pits are covered by a layer. The underneath surface is still perceptible. Original magnification 5000X Bar=10μm.
C. Scanning electron microscopic graph and XRD spectrum of enamel surface demineralised with 37% ortophosphoric acid and brushed in vitro 2 times (1 min) a day for 15 days with a paste containing a mix of 100nm and 20 nm CHA. The surface is completely covered by a globular layer. The XRD spectrum are compatible with those of CHA. Original magnification 5000X Bar=10μm.
