Effect of Different Surface Treatments on the Bonding Strength of Three Different Post Biomaterials to a Resin-Based Luting Agent.

The aim of this study was to evaluate how different post-surface treatments affect the ability of luting cement to bond three different dental post materials to a resinous surface. The study analyzed a total of 108 posts categorized into three main groups: stainless steel, cast, and fiber posts. Next, the core group was divided into four subgroups ( Stainless steel posts exhibited the lowest bond strength, whereas fiber posts demonstrated the highest shear bond strength. When it comes to surface treatments, dental post-surfaces treated with sandblasting have been found to exhibit the highest bond strength, outperforming other methods. Comparing all methods of surface modification, sandblasting with 50 um Al
