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 ...

Solubility and disintegration of zinc phosphate cement
Biomaterials, 1992The mechanism of erosion of a zinc phosphate cement was studied using two experimental procedures: discs of dental cement were immersed in distilled water under unrenewed conditions as defined by ISO standard; or discs were immersed under continuously running distilled water to simulate the oral environment.

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

Recently, zinc-releasing bioceramics have been the focus of much attention owing to their bone-forming ability. Thus, some types of zinc-containing calcium phosphate (e.g., zinc-doped tricalcium phosphate and zinc-substituted hydroxyapatite) are examined and their osteoblastic cell responses determined.

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.

Crystallization of zinc phosphate cement
The Journal of Prosthetic Dentistry, 1965Abstract A microscopic study indicated that ZnHPO 4 ·3H 2 O was formed during the crystallization of zinc phosphate cement powder and liquid. Long crystals of ZnHPO 4 ·3H 2 O radiated from a nucleus of crystallization. Apparently, the surface tension force plays a role in partially inhibiting the growth of these crystals.
