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.

Structure of Zinc Phosphate Dental Cement
Journal of Dental Research, 1971The zinc phosphate cement structure consists of excess zinc oxide particles in a non-crystalline, amorphous phosphate matrix. Crystals of hopeite (Zn3(PO4) 2·4H2O) can grow from the cement surface if excess water is present. Extensive pores and surface layers of crystals, which are dependent on moisture conditions, affect the strength and adhesive ...

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.

Effect of two desensitizing agents on crown retention using zinc phosphate cement
International journal of oral care & research, 2018Introduction: Preparation of vital teeth involves removal of sound tooth structure, which causes opening of dentinal tubules, thereby causing displacement of the dentinal tubular fluid, leading to dentinal hypersensitivity. After cementation of crowns in

Influence of phytic acid on zinc phosphate cement
Acta Odontologica Scandinavica, 1994The 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, 1972When 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·P2 O5 · 4 H2O).
