Hydraulic fast‐setting calcium silicate cement for crown cementation
Journal of Prosthodontics, EarlyView.Abstract Purpose This study evaluated film thickness, diametral tensile strength (DTS), and crown retentive strength of hydraulic fast‐set calcium silicate cement (fast‐set CSC) compared to conventional luting cements. Materials and Methods Fast‐set CSC was compared to zinc phosphate cement and glass ionomer cement.
