Background: The use of dissimilar materials used as posts, luting agents, and the core often makes the restorative procedure quite complicated, as each material demands its own technical process. Furthermore, it may not necessarily result in better collective physical properties. Aim: The aim of this study was to analyze the pushout bond strength of a zirconia-based core buildup material in cementing two fiber posts. Methods: Eighty single-rooted mandibular premolars were decoronated, endodontically treated, post space prepared, and randomly assigned to one of the following four groups: carbon fiber post luted with PermaCem 2.0, carbon fiber post luted with LuxaCore Z Dual, glass fiber post luted with PermaCem 2.0, and glass fiber post luted with LuxaCore Z Dual. Pushout bond strength was evaluated in a universal testing machine for each of the 2 ± 0.5 mm sections obtained from the samples (total 160 sections) Statistical Analysis: One-way ANOVA and post hoc tests were used for statistical analysis. Results: The glass fiber posts cemented with LuxaCore Z showed significantly higher pushout bond strength (P < 0.001). Conclusion: LuxaCore Z Dual-core build material was more effective as a luting agent for glass fiber post cementation.
