摘要

The setting processes in KetacCem, AquaCem and Fuji I glass-ionomer dental cements (GIC) as well as in the resin-modified glass-ionomer dental cement (RM-GIC) Fuji Plus have been studied by proton spin-lattice, T-1, and spin-spin, T-2, relaxation. The setting time dependence of the degree of hydration was studied as well. In contrast to zinc oxide dental cements, the changes in T-1 and T-2 are determined by the interactions of the water with the internal surface. Proton nuclear magnetic resonance relaxation is thus suitable to follow the setting of GIC and RM-GIC and gives valuable information on the GIC hardening dynamics.
