Abstract

The aim of this study was to determine the flexural strength and modulus of elasticity of five resin composites: Tetric Ceram, Ecusit, Spectrum TPH, Filtek Z-250, Degufill mineral; and two polyacid-modified resin composites: Luxat e lonosit. Five rectangular specimens of each material were prepared (22×2×2 mm). They were light-cured, first in the middle and after in both extremes, by means of a visible-light curing unit. The specimens were stored in water at 37° C for 48 hours and ground to eliminate the resin layer inhibited by oxygen. Three-point bending test was performed in an universal testing machine (Instron) at a cross-head speed of 1mm/min. Results were expressed in MPa and analysed by ANOVA and Student-Newman-Keuls tests (p<0.05). Flexural strength and modulus of elasticity of the polyacid-modified resin composite, lonosit, were significantly lower than the values obtained for the rest of the materials evaluated.
