“…When evaluating using dislocation resistance, D'Arcangelo and others 45 showed that thicknesses of 100 µm or 120 µm presented better results than either greater or lesser thicknesses. Grandini and others 46 evaluated resin cement thickness after luting anatomic and standardized fiber posts into root canal preparations.…”

“…[8][9][10][11][12][13][14] When the cement layer is too thick, the retention of the fiber-reinforced post is significantly decreased. 18 Resin cement thicknesses greater than 100 μm were observed between the interfaces of dentin and fiber-reinforced post at the 1-mm, 4.5-mm, and 8-mm level of the root. 17 No scientific evidence supports the effectiveness of the physical properties of resin cements, including their bonding, when an appropriate post space is produced.…”

“…17 However, an excessively thick cement layer in that region may not confer the requisite mechanical properties to withstand occlusal loading. 18 The maximum tensile or shear stress, which is primarily located at the post/cement/dentin interface, decreases with the increasing modulus of elasticity 19 ; the modulus of elasticity of the foundation composite resins is higher than that of the resin luting cement. 20,21 The constitution of the core and post, which forms a mechanically homogeneous unit with root dentin, is difficult to determine and could be compromised if the dual-polymerizing resin cement used does not reach an adequate monomer conversion.…”

“…Pullout tests 15,16) , push-out tests [17][18][19] , and microtensile tests 20) are typically used to test the adhesion at the interface between the post and the restoration material. Push-out tests and microtensile tests were inadequate to test the adhesion of the hollow post in this study because a severed specimen is required for such tests.…”
