“…Various studies have used different mechanical and chemical surface treatments to improve the bond strength of zirconia ceramics to resin cements. 12,15,22,35 Sahafi et al 9 reported that Cojet treatment (silicate-coated particles of 30 mm, silane) most increased the bond strength of zirconia posts to root canal dentin. However, etching with hydrofluoric acid (with or without silane treatment) decreased the bond strength of zirconia posts to root dentin.…”

“…8,9 The wide range of esthetic post systems, including fiber-reinforced composite resin posts and zirconia ceramic posts, are available. [10][11][12] The use of zirconia as a post and core material was first introduced in 1993 13 because of its excellent mechanical properties, including high chemical stability, modulus of elasticity, and strength, as well as its esthetic properties. [14][15][16][17] The loss of post retention is one of the most common reasons for the failure of post-retained restorations.…”

“…The initial dentin bonding was performed as described in Table 1 . The new composite cylinders were cemented to the dentin surfaces using finger pressure 2 4 25 26 by the same researcher, and excess cement was removed with a brush. Samples were then light polymerized (Elipa S10; 3M ESPE) with a light intensity of 1200 mW/cm 2 for 30 seconds on the bonding area.…”

PURPOSECementation failures of restorations are frequently observed in clinical practice. The purpose of this study is to compare the effect of initial and repeated bonding on the bond strengths of different resin cements to enamel and dentin.MATERIALS AND METHODSNinety human maxillary central incisors were bisected longitudinally. The 180 tooth halves were divided into 2 groups (n = 90) for enamel and dentin bonding. The enamel and dentin groups were further divided into 3 groups (n = 30) for different resin cement types. Composite resin (Filtek Ultimate) cylinders (3 × 3 mm) were prepared and luted to enamel and dentin using Variolink II (Group V), RelyX ARC (Group R), or Panavia F 2.0 (Group P) resin cement. After 24 hours, initial shear bond strengths of the resin cements to enamel and dentin were measured. Using new cylinders, the specimens were de-bonded and re-bonded twice to measure the first and the second bond strengths to enamel and dentin. Failure modes and bonding interfaces were examined. Data were statistically analyzed.RESULTSInitial and repeated bond strengths to enamel were similar for all the groups. The first (15.3 ± 2.2 MPa) and second (10.4 ± 2.2 MPa) bond strengths to dentin were significantly higher in Group V (P<.0001). Second bond strengths of dentin groups were significantly lower than initial and first bond strengths to dentin (P<.0001).CONCLUSIONAll resin cements have similar initial and repeated bond strengths to enamel. Variolink II has the highest first and second bond strength to dentin. Bond strength to dentin decreases after the first re-bonding for all resin cements.

“…According to some studies, increasing the diameter of the post does not significantly affect the retention capacities. However, it can increase the strength of the post and thus increase the risk of a root fracture [ 19 ] [ 20 ].…”

BACKGROUND:Prefabricated zirconium upgrading systems were examined to satisfy aesthetic needs in endodontically treated teeth. Endodontically treated teeth, together with non-metallic posts and superstructure, are substructures that enable the production of prosthetic structures that will allow aesthetics, resulting from normal light transmission. To investigate and analyse the retention of zirconium post systems cemented with RelyX Unicem 2 Automix (RLX) cement with Pull-out test.AIM:To examine the retention of zirconium post systems, cemented with Multi-Link Automix (MLA) cement and RelyX Unicem 2 Automix (RLX) cement with Pull-out test.MATERIAL AND METHODS:In this study were used, 120 post systems of the company ZIRIX NORDIN - Switzerland, with different diameters d1 = 1.2, were used: d2 = 1.35, d3 = 1.5, and two types of resin cements: Multilink Automix-Ivoclar (MLA), and RelyX Unicem 2 Automix (RLX) - 3 M ESPE.RESULTS:The analysis of the extraction force in newtons (N) zirconium post systems of Multilink Automix cement according to subgroups of three diameters is consequently 481.3 ± 1.9 vs 462.9 ± 4.5 vs 454.2 ± 2.2. The analysis of the extraction strength in the newtons (N) zirconium post systems of RelyX Unicem 2 Automix cement in the entire sample is 577.9 ± 6.1 N.CONCLUSION:The largest diameter of the posts significantly increases the resistance of fractures compared to the smaller two diameters used in the experimental study.
