Abstract

The main aim of this study was to evaluate the influence of porosity, microstructure, and chemical composition on the wear and compressive strength of dental glass-ionomer or resin composite. Cylindrical samples (6 × 4 mm) were prepared from a nano-hybrid resin composite (Grandio®SO/RC, VOCO), a resin-modified glass ionomer (Vitremer™/VI, 3 M-ESPE) and a conventional glass ionomer (Ionofil®Molar/CO, VOCO). Porosity and topography of the materials were evaluated by optical and scanning electron microscopy (SEM). Roughness was evaluated by Ra and Rt parameters at 0.1 mm/s under cut-off of 0.8 mm. Then, compressive tests were performed at 1 mm/min. Wear tests were carried out at 20 N, 2.5 mm of displacement, at 1 Hz for 90 min in artificial saliva solution. The results were statistically analyzed with a one-way ANOVA and Tukey’s test (p
