Sensibilidade do colo dental. Uma nova alternativa terapêutica.
(1990-05-01)
The cervical hypersensitivity tooth was analysed and treated by application of a varnish with high fluoride ions content (Duraphat) and of a glass ionomer cement usually indicated to cavity lining (XR-ionomer-Kerr). This ...
Stabilization of fluoroindate glasses by magnesium fluoride
(1997-05-12)
This paper describes the stabilizing effect of MgF2 on the binary system InF3-BaF2. A complete investigation of the In-Ba-Mg system led to samples up to 5 mm in thickness. Further optimization of this system was achieved ...
Thermal properties of fluoride glasses and their gel precursors
(Kluwer Academic Publ, 2004-01-01)
Xerogels were prepared from zirconium, barium, aluminum, lanthanum and lithium acetates, corresponding to a Li containing ZBLA composition. The study of their thermal properties (DSC, TG/DTG, FT-IR) showed that they might ...
Scandium fluorides
(1997-11-14)
A new modification of scandium fluoride has been synthesised. The compound is deficient in fluorine, with the composition ScF2.76. It belongs to the tetragonal system, lattice parameters being a = 3.792 and c = 6.740 Å and ...
Effect of Fluoride-containing Mouthrinses on the Translucence of Resin Modified Glass Ionomer Cements
(ABM, ABC, ABPol, 2002-10)
The aim of this in vitro study was to assess the effect of different fluoride-containing mouthrinses on the translucence of resin-modified glass ionomer cements, as a function of the restorative material used, the ...
In situ anticariogenic potential of glass lonomer cement
(1993-01-01)
The purpose of this study was to compare the amount of fluoride in plaque formed on glass ionomer cement or composite and to evaluate the effects of fluoride released on growth of cariogenic microflora, fluoride uptake, ...
Stabilization of fluoroindate glasses by magnesium fluoride and other heavy metal fluorides
(Sociedade Brasileira de Química, 1998-06-01)
Their extended transparency in the IR makes them attractive for use as optical fibers for CO laser power delivery and optical amplification. This paper firstly describes the spectacular stabilizing effect of MgF2 on the ...
Effect of lead fluoride incorporation on the structure and luminescence properties of tungsten sodium phosphate glasses
(Elsevier B.V., 2015-11-01)
Tungsten phosphate glasses are known to be promising materials for several applications in optics such as non linear optical properties, lower phonon energy or photochromic effects related with tungsten oxide incorporation ...
Structural and optical study of glasses in the TeI2-GeO2-PbF2 ternary system
(Elsevier B.V., 2017-05-01)
New glass compositions were investigated in this specific proportion (90-x)TeO2-10GeO(2)-xPbF(2) in order to study the influence of lead fluoride content on the thermal, structural and optical properties. Glass samples ...
Stabilization of fluoroindate glasses by magnesium fluoride and other heavy metal fluorides
(Soc Brasileira Quimica, 1998-05-01)
Indium fluoride-based glasses constitute a new generation of materials for applications in the midinfrared spectral range. Their extended transparency in the IR makes them attractive for use as optical fibers for CO laser ...
