“…Several previous studies also reported that resin cement or primers containing MDP could increase the bond strength by approximately 8 to 72 MPa on 3Y-TZP [16,18,19,22,23] and translucent zirconia [40,41]. Phosphoric methacrylate ester has also been reported to increase the bond strength of 3Y-TZP [24,25]. The results of this study showed that the shear bond strength of the primer containing MDP and the adhesive containing phosphoric methacrylate ester showed no significant differences, which was similar to the results of previous studies [37,43].…”

“…This procedure should be performed to obtain durable and effective bonds [19,20] which are comparable with the bonding in metal alloys [21]. Various kinds of phosphate monomers have been included in resin cements and primers, including 10-methacryloyloxydecyl dihydrogen phosphate (MDP), phosphate methacrylate ester, glycerol phosphate dimethacrylate (GPDM), dipentaerythritol penta-acrylate monophosphate (PENTA), and phosphoric acid acrylate, all of which contribute to the enhancement of bond strength of zirconia [16,18,19,[22][23][24][25]. Previous studies have reported shear bond strengths of zirconia to composite resins ranging from 2 to 25 MPa [20,24].…”

Purpose: The shear bond strength of conventional zirconia (3Y-TZP), translucent zirconia (5Y-PSZ), and titanium alloy (Ti6Al4V) thermocycled using different phosphate monomer resin cements were investigated. Methods: In this study, 120 specimens of 3Y-TZP, 5Y-PSZ, and Ti6Al4V were cemented to nanocomposite resin cylinders using PANAVIA™ V5 and Rely X™ U200. The bond area and resin cement thickness were controlled as per ISO 29022:2013 and 4049:2009. Each resin cement group was used with/without the Clearfil ceramic primer plus. The shear bond strength of the 12 groups was statistically analyzed using two and one-way ANOVA to determine the properties of the different materials and resin cements (α = 0.05). The mode of failure was observed using scanning electron microscopy (SEM) and energy-dispersive X-ray spectroscopy (EDS). Results: The titanium alloy groups showed better shear bond strength than the zirconia groups (p < 0.05). PANAVIA™ V5 without primer showed significantly lower shear bond strength than other cements in zirconia and titanium alloy specimens (p < 0.05). Titanium alloy with Rely X™ U200 with a Clearfil ceramic primer plus showed the highest shear bond strength (6.37 ± 1.60 MPa). SEM images showed mixed failures in zirconia groups and cohesive failures in titanium alloy groups. Conclusions: The titanium alloy showed better shear bond strength than zirconia when the Clearfil ceramic primer plus was used. The primer solution containing MDP and resin cement with phosphoric methacrylate ester showed similar shear bond strength with 3Y-TZP and 5Y-PSZ. The resin cement without phosphate monomers demonstrated the least shear bond strength.

“…From our experiment, the highest percentages of absorption were recorded for the sample 4 (with the lowest organic matrix concentration) and the sample 3. For the sample 4, the acidic nature of the phosphorylated methacrylate can cause erosion of surfaces of samples tested by us due to hydrolysis of the methacrylate ester bond in water [15]. The sample 1 showed a low percentage of water absorption and the lowest percentage of saliva absorption compared to the other investigated materials.…”

The aim of this in vitro study was to evaluate the characteristics of four commercial dental composites: two dual-curing luting resin cements and two indirect composites for crowns and bridges. The novelty of the study consists in the use of combined characterization methods for the investigated materials, namely: after maintaining the samples in the water/ artificial saliva, besides sorption, the surface degradation of the samples was observed after their immersion period; thereafter, the immersion medium was lyophilized and then the percentage of residual monomer found in the medium was determined by HPLC. After 44 days, small concentrations of monomers have been determined in the aqueous/saliva extracts. SEM images show that the samples from each class of material, with a higher content of inorganic filler, exhibit a larger erosion of the surfaces after contact with water compared to the other two samples that show a larger erosion of surfaces after contact with saliva than with water. The surface of the dual-curing resin cement with a higher content of inorganic filler is the smoothest from the samples exposed to saliva, instead the other resin cement is the roughest, as shown by AFM analysis. The overall observation reveals that the samples kept in saliva are rougher than the ones kept in water. Smooth surface materials of both classes of materials ( with a higher content of inorganic filler) have absorbed a higher amount of water / saliva compared to materials with a rougher surface.Water sorption in the composite resins is influenced by the hydrophilicity of the monomers, the nature and size of the inorganic filler particles, and the quality of the matrix / filler interface.

RESUMOOs cimentos resinosos são materiais com uma abrangente utilização e empregabilidade no meio odontológico, utilizado em cimentações de laminados, coroas totais, restaurações parciais, retentores intrarradiculares e braquets ortodônticos. São reconhecidos pela alta resistência adesiva, resistência ao desgaste e insolubilidade. O objetivo foi avaliar a cimentação adesiva dos cimentos resinosos, quanto a sua aplicabilidade e melhor desempenho no meio clínico, conhecido por sua técnica sensível e sua competência na união do substrato aos elementos dentários possui diversas apresentações, não havendo ainda um cimento com características ideais para todos os casos, desta forma precisamos conhecer as propriedades físicas e químicas para melhorar a aplicação clínica. Dos 55 artigos selecionados, foram aplicados alguns parâmetros de inclusão e exclusão, totalizando 41 artigos para essa revisão de literatura. Sendo assim, embora os cimentos resinosos ainda sejam um material em evolução no mercado e nos estudos quanto a melhor composição, apresentação, aplicação e custo benefício, os cimentos resinosos associados aos sistemas adesivos é o material ideal para cimentação adesiva em relação aos cimentos convencionais.
