Influence of pH and oxygen-inhibited layer on fluoride release properties of fluoride sealant.
J. Dent. 35(4) , 275-81, (2007) This study tested the hypothesis that the oxygen-inhibited layer on a light-cured methacrylate based resin and the pH of the storage medium would increase significantly the initial fluoride release and long-term release rate from fluoride dental sealant.Forty... |

High-frequency and -field EPR and FDMRS study of the [Fe(H2O)6]2+ ion in ferrous fluorosilicate.
J. Magn. Reson. 213(1) , 158-65, (2011) The complex [Fe(H2O)6]SiF6 is one of the most stable and best characterized high-spin Fe(II) salts and as such, is a paradigm for the study of this important transition metal ion. We describe high-frequency and -field electron paramagnetic resonance studies o... |

Fatal cases of acute suicidal sodium and accidental zinc fluorosilicate poisoning. Review of acute intoxications due to fluoride compounds.
Forensic Sci. Int. 206(1-3) , e20-4, (2011) Fluoride, of all inorganic substances, is among the least likely to be identified by a routine toxicological analysis. Acute poisonings with salts of hydrofluoric or fluorosilicic acid, however, although relatively uncommon, may occur. Some fluorosilicates, s... |

Structure and vibrational study of the trimethylammonium hexafluorosilicate [(CH3)3NH]2SiF6 compound.
Spectrochim. Acta. A. Mol. Biomol. Spectrosc. 59(4) , 851-7, (2003) The X-ray powder diffraction pattern of [(CH(3))(3)NH](2)SiF(6) was obtained and indexed on the basis of a centred cubic unit cell with the P4(1)32 as the likely space group. The Infrared and Raman spectra of this compound have been recorded at room temperatu... |

Regulation of fluoride ion release from Na2SiF6 contained in resin based on hydrophobic siloxane layer coating.
J. Oral Rehabil. 29(7) , 675-81, (2002) Regulation of fluoride release from restorative resin or sealant is beneficial to patients as it will prevent the occurrence of the secondary caries. In this study, we evaluated whether or not the formation of a hydrophobic polysiloxane layer on the surface o... |
