Biological Evaluation of Zinc Phosphate Cement for Potential Bone Contact Applications [PDF]
Biomedicines, 2023 Zinc phosphate cement is used in dentistry to lute crowns and bridges. So far, its biocompatibility for other applications has not been studied. This paper reports the biocompatibility of zinc phosphate towards MG63 cells, testing both the material ...

Rotational Viscometry of a Zinc Phosphate and a Zinc Polyacrylate Cement [PDF]
Journal of Dental Research, 1977 The rheological properties of a zinc phosphate and a zinc polyacrylate cement were investigated using a rotational viscometer. The effects of time, temperature, shear rate, and spindle geometry on the measured viscosities were evaluated. Results indicated that both cements exhibited Newtonian behavior.

Structure of Zinc Phosphate Dental Cement
Journal of Dental Research, 1971 The zinc phosphate cement structure consists of excess zinc oxide particles in a non-crystalline, amorphous phosphate matrix. Crystals of hopeite (Zn 3 (PO 4 ) 2 ·4H 2 O ...

Influence of phytic acid on zinc phosphate cement
Acta Odontologica Scandinavica, 1994 The influence of phytic acid on the properties of zinc phosphate cement was studied by adding 2-13 wt% phytic acid to the liquid. Improved mechanical strength and stability were found for some cements prepared from commercial powders when liquids with increased phytic acid content were used.

Surface Structure of Zinc Phosphate Dental Cements
Journal of Dental Research, 1972 When zinc phosphate cement is formed enclosed between a glass plate and a tooth surface, it retains the excess moisture available at the time of setting. This causes the cement surfaces to become covered with weakly held crystals of hopeite (3 ZnO·P 2 O 5

Enamel Corrosion Produced by Zinc Phosphate Dental Cement
Journal of Dental Research, 1976 The surface of tooth enamel that had been left in contact with a phosphoric acid solution or a zinc phosphate cement mix was studied by scanning electron microscopy. Both treatments modified enamel surface topography. The modifications were represented by cavities of varying extension and depth.
