Sažetak
The objective of the study was to compare the compressive strengths of two restorative materials with or without light curing nano-filled coating, after cyclic loading. Four groups of samples (n=7): (1) Equia Fil GC (Tokyo, Japan) uncoated ; (2) Equia Fil coated with Equia Coat (GC Tokyo, Japan) ; (3) Equia Forte Fil GC (Tokyo, Japan) uncoated and (4) Equia Forte Fil coated with Equia Forte coat, were subjected to cyclic loading (240, 000 cycles) using a chewing simulator (MOD, Esetron Smart Robotechnologies, Ankara, Turkey). Compressive strength measurements were performed according to ISO 9917-1:2007 using a universal mechanical testing machine (Instron, Lloyd, UK). Other specimes than those used for compressive strength measurements were analysed using SEM. Kruskal Wallis test and factorial ANOVA analysis showed that there were no statistically significant differences between Equia and Equia Forte irrespective of the coating (p<0.05), but a trend of increasing compressive strength in the coated samples was noticed. The results of this study showed that the compressive strength after cyclic loading was higher in the case of Equia Fil and Equia Forte Fil when the samples were coated prior to cyclic loading, but the difference was not significant.
