Abstract

Background: Dual-cure resin composites are widely used for core build-ups, yet limited comparative data exist between glass ceramic and zirconia filled core build up materials. Aim: To compare the flexural strength, compressive strength and fracture resistance of the two core build up materials. Materials and Methods: Sixty specimens were prepared and divided into two groups (n=30). Subgroups (n=10) were tested for flexural strength, compressive strength and fracture resistance using standardized protocols and a universal testing machine. Data were analyzed with t-test and ANOVA (p < 0.05). Results: Fusion Core DC Flo showed significantly higher flexural strength (p < 0.05), while compressive strength and fracture resistance were comparable between groups. Conclusion: Both materials exhibited satisfactory performance, with Fusion Core DC Flo offering an advantage in flexural strength.
