“…13 The chemical interactions between functional monomers and dentine substrates have been studied in detail. 13,[25][26][27][28][29] However, few studies had been conducted on the interaction of deproteinised dentine with commercial adhesives containing functional monomers. In the present study, three self-etching adhesives were selected and bonded to deproteinised dentine.…”

“…For the longevity of dental restorations, “gap-free” continuous cement margins are important [21], to avoid plaque accumulation and subsequent secondary caries the interface between restorative materials and tooth hard substances must be morphologically as perfect as possible [22], even though no luting material is able to achieve a perfect marginal seal [1,23]. …”

Objectives: To evaluate the microleakage and marginal gap of various luting materials after cementing ceramic crowns. Methods: Cervical margins of human molars were designed as circular chamfers. Cementation of full-contour ceramic crowns was conducted with zinc-phosphate cement (Harvard cement), resin cement (Panavia F 2.0) and self-adhesive resin cements (RelyX Unicem, BifixSE, MaxCem Elite, PermaCem2.0, G-Cem). Aging of specimens was performed in artificial saliva, at 37 °C for four weeks and thermocycling. The marginal gap was measured with a scanning electron microscope and silver precipitation within the microleakage. All data were compared statistically. Results: Independent of the margin preparation, the highest median value for microleakage was 320.2 μm (Harvard cement), and the lowest was 0 μm (Panavia F 2.0). The median value for enamel was 0 µm and for dentin 270.9 μm (p < 0.001), which was independent of the luting material. The marginal and absolute marginal gaps were not significantly different between the tested materials. There was no correlation between microleakage and the marginal gaps. Conclusion: Significant differences in microleakage were found between the tested luting materials (p < 0.05). Independent from the luting materials, the microleakage in dentin showed significantly higher values than in enamel.

“…Cohesive failure within the resin cement was observed in the MD and MD-e groups, with a better bonding performance, despite the fact that they exhibited completely different surface characteristics. The balanced molecular structure of MDP makes its soluble in water and dimethacrylate monomers 20) . In the MD group, MDP accumulated after primer application and air drying may have dissolved into and polymerized with the dimethacrylate monomers in the resin cement.…”

“…Ethanol evaporates form the primer on the ceramic surface while air dry, unreacted monomer must have accumulated and left unevenly on the surface. Phosphate functional monomers possess both hydrophilic and hydrophobic characteristics, and the initial dentin bond strength is influenced by the length and hydrophilicity of their spacer chains 20) . Thus, in the absence of ethanol cleaning, the hydrophilic parts of the phosphoric functional monomers were scattered on the surface, resulting in lower contact angles than those of the Con group.…”

This study aimed to evaluate the bond strength of a resin cement to yttria-stabilized tetragonal zirconia polycrystals (Y-TZPs) treated with three different phosphate functional monomers containing primers by measuring the water contact angle. Seventy Y-TZP discs were divided into seven experimental groups (n=10), including an untreated (control) group. Specimens were treated with one of the following monomers: MDP (MD), GPDM (GP), and Phenyl-P (PP). After primer application and air drying, half the treated specimens were ultrasonically cleaned in ethanol for 2 min (MD-e, GP-e, and PP-e), and contact angles were measured. The tensile bond strength test was performed after storage for 24 h in 37°C water. The contact angle on the MD-e surface (64°) was significantly higher than that on the Con, GP-e, and PP-e surfaces (51°-52°). The application of the MDP-containing primer resulted in significantly higher bond strength between Y-TZP ceramics and a resin cement.
