Compariative study of the physical properties of a polyacid-modified composite resin and a resin-modified glass ionomer cement

摘要

Objectives: The physical properties of the resin-modified composite resin Dyract (Dentsply) and the resin-modified glass ionomer cement Fuji II LC (GC) were compared, and the effect of water sorption on these properties was studied. Methods: Compressive, diameteral compressive and flexural strengths wee measured using specimens aged up to three months. The Vickers hardness and the water erosion were also determined. The specimens were stored at 37 deg. C under five different conditions, chosen to Vary the water sorption of the samples. The results were analyzed using a multi-factor analysis of variance.
