Purpose: To assess the degree of conversion (DC) dual-curing composite cements when cured through ceramic-veneered zirconia disks. Methods: Portions mixed cement, either G-CEM LinkForce (GC), Panavia V5 (Kuraray Noritake) or ResiCEM (Shofu), were placed on ATR crystal a Fourier Transform Infrared Spectroscope (FTIR; iS50, Thermo Scientific) and squeezed to 100-µm film thickness using microscopy...
