“…[ 19 ] Torabi Ardakani et al found that this zirconia primer significantly strengthened the bond between zirconia posts and the root canal dentin cemented with either self-etch or self-adhesive resin cement (Panavia F and Clearfil SA luting cement). [ 18 ] Our findings were different from those of the previous studies can be related to the difference in the nature of the tooth and core materials (Ni-Cr, amalgam, and composite resin).…”

“…Studies were performed to find out if the zirconia–resin cement bond could be strengthened using a new zirconia primer (a mixture of organophosphate and carboxylic acid monomer). [ 18 19 ] Copolymerization occurs between the monomers of resin luting agent and the organofunctional constituent of the organophosphate monomer. Moreover, it is believed that the present phosphoric acid groups would establish a bond with the metal oxide in zirconia.…”

“…This material allows copolymerization between the organofunctional part of the organophosphate monomer and the monomers of the resin luting agents, besides the establishment of a bond between its phosphoric acid groups and the metal oxide in zirconia. [ 17 18 ] Carboxylic acid is the other constituent monomer in this primer which contributes to the development of the bond. [ 19 ]…”

Aim: Considering the importance of bond strength of zirconia ceramic to different core materials, this study aimed to evaluate the effect of a new zirconia primer, a mixture of organophosphate and carboxylic acid monomers, on the bond strength of zirconia to three core materials cemented with a self-adhesive resin cement. Materials and Methods: The study was done on 36 disk-shaped zirconia specimens in the case (receiving new zirconia primer) and control groups ( n = 18) and three core material subgroups ( n = 6) (amalgam, nickel–chromium [Ni-Cr], and composite resin). A self-adhesive resin-based luting agent bonded the two parts together. The shear bond strength was tested and the facture modes were determined. Two-way ANOVA and Tukey's honestly significant difference tests were used for data analyses (α = 0.05). Results: Zirconia primer could not significantly increase the bond strength of zirconia ceramic to different core materials ( P = 0.754). Composite resin and amalgam cores showed significantly higher bond strength than Ni-Cr core ( P = 0.001). On using zirconia primer, 100% of failures of composite resin cores were cohesive inside the core material, 75% in amalgam core and 100% in Ni-Cr core were adhesive. Conclusions: The use of new zirconia primer based on organophosphate/carboxylic acid monomers could not enhance the bond strength of zirconia ceramic to different core materials. The bond strength of zirconia to amalgam and composite resin cores was higher than that to Ni-Cr core material.

“…The bond strength was calculated in MPa using the maximum fracture load (N) divided by the area (mm 2 ) of the resin [23]. Failure modes were analyzed by using stereomicroscopy (Wild Heerbrugg AG, Heerbrugg, Switzerland) at 10× magnification or by SEM.…”

This study analyzed the shear bond strength (SBS) of resin composite on zirconia surface to which a specific conditioner was applied before sintering. After sintering of either conditioner-coated or uncoated specimens, both groups were divided into three subgroups by their respective surface modifications (n = 10 per group): no further treatment; etched with hydrofluoric acid; and sandblasted with 50 µm Al 2 O 3 particles. Surfaces were characterized by measuring different surface roughness parameters (e.g., R a and R max ) and water contact angles. Half of the specimens underwent thermocycling (10,000 cycles, 5-55˝C) after self-adhesive resin cement build-up. The SBSs were measured using a universal testing machine, and the failure modes were analyzed by microscopy. Data were analyzed by nonparametric and parametric tests followed by post-hoc comparisons (α = 0.05). Conditioner-coated specimens increased both surface roughness and hydrophilicity (p < 0.01). In the non-thermocycled condition, sandblasted surfaces showed higher SBSs than other modifications, irrespective of conditioner application (p < 0.05). Adhesive fractures were commonly observed in the specimens. Thermocycling favored debonding and decreased SBSs. However, conditioner-coated specimens upon sandblasting showed the highest SBS (p < 0.05) and mixed fractures were partially observed. The combination of conditioner application before sintering and sandblasting after sintering showed the highest shear bond strength and indicated improvements concerning the failure mode.
