| Abstract Purpose: To determine the impact of core materials type on Lithium disilicate glass-ceramic shear bond strength when both are bonded using conventional resin cement. Materials and Methods: Thirty-Two cylinders of IPS e-max Press were created, and core specimens including dentin, composite resin, zirconia, and RMGI were made following the recommendations of the manufacturer. The ceramic cylinders were bonded to core groups using (Multilink N) conventional resin cement, and all samples underwent artificial aging via water bath for 150 days and thermocycled for 5000 cycles. A universal machine was used to find the specimens’ SBS, and a stereomicroscope was used for failure inspection. In addition, the SEM was utilized for further evaluation. Results: According to the data, there was a noticeable statistical difference in the mean SBS values (P<0.05), and the performance of foundation materials. The composite resin groups came out on top with the highest mean SBS, while the dentin and zirconia groups had the lowest mean SBS. Conclusion: When selecting a core material, it is important to remember that the type of material used can significantly impact SBS. While various options are available, composite resin is often preferred due to its superior properties and performance. | ||
