Among which GICs and zinc phosphate cements
are the most widely used.
GIC was intermediate between resin cement and zinc phosphate followed by zinc phosphate cement showing the lowest bond strength with both the metals.
16) for zinc phosphate cement demonstrated a mixed mode of fracture with predominantly adhesive failure.
Zinc phosphate cement, exhibits adequate film thickness to comply with American Dental Association.
The null hypothesis was that the time elapsed between the luting of the cast post-and-core with zinc phosphate cement and the core-finishing procedures would not influence the tensile strength of these retainers to endodontically treated roots.
The cast posts-and-cores were luted with zinc phosphate cement prepared according to the manufacturer's instructions (Zinc Cement; SS White, Rio de Janeiro, Brazil).
The core-finishing procedures performed at different time intervals after cast posts-and-cores were luted with zinc phosphate cement did not influence the tensile strength of these retainers to endodontically treated roots (Tables 1 and 2).
Zinc phosphate cement is one of the oldest material used for cementation of indirect restorations8,9 and orthodontic appliances.
In this study 100 specimens of glass ionomer and zinc phosphate cement each were tested for solubility in different pH mediums.
