Purpose: The aim of the study was to evaluate the shear bond strength (SBS) of different resin cements after zirconia surface treatments. Materials & Methods: A total of 60 zirconia discs (3x7mm) were prepared and divided into 3 main groups according to the surface treatments as control (C), sandblasting (SB), and tribochemical silica coating (TC). Main groups were divided into two subgroups according to two different resin cements were applied. No surface treatment was applied to the samples in C group. 50μm Al2O3 particles were applied to the samples in SB group for 10 s at a distance of 10 mm under 4 atm. TC group were tribochemically coated with alumina particles. Self-adhesive resin (ME) and multi-system dual-cure adhesive resin (NX3) was applied to the subgroups. After cementation, all samples were tested for SBS. SBS values were statistically analyzed by the Kruskal-Wallis and Mann-Whitney U tests. Results: Regardless of the cement type, SBS values of the surface treated samples were statistically different (p <0.001). Group SB was determined as the group with the highest SBS value. This group was followed by Group C and Group TC, respectively. The SBS values of the samples according to the resin cements and surface treatments were statistically significantly different (p<0.001). SBS values of the samples cemented with NX3 resin cement were found to be higher than the samples treated with ME resin cement. Conclusion: SB increased resin bond to zirconia. It is more advantageous to use multi-system dual cure adhesive cements in zirconia cementation.

Purpose: To evaluate the effect of aging and different surface treatments on micro-shear bond strength of two resin cements to resin nano-ceramic composite blocks using an in-vitro study. Materials and methods: Blocks of resin nano-ceramic (Lava Ultimate, 3M, St Paul, Minnesota, USA) were used to prepare eight plates having the following dimensions: (14mm × 12mm × 2mm). After plates preparation they were assigned to two main groups according to the surface treatment applied, either hydrofluoric acid etching and silane or sandblasting and silane. Scanning electron microscope (SEM) was used to analyze the surface topography of the Lava-Ultimate plates before and after application of surface treatments. Two resin cements were used; dual cured adhesive resin cement (Bifix QM, VOCO, Cuxhafen, Germany) and dual cured self-adhesive resin cement (Bifix SE, VOCO, Cuxhafen, Germany) to create a five resin micro-cylinders received on each lava ultimate plate. Ten specimens from each subgroup were tested after 24 hours and the other ten specimens were tested after aging in saline for 6 months. Micro-shear bond strength test was applied until failure. . Multi-factorial ANOVA test and One-way ANOVA followed by pair-wise Tukey’s post-hoc tests were used to analyze the data. Results: Both resin cements showed statistically significant decrease on bond strength after aging. Before aging, both surface treatments with adhesive resin cement showed statistically significant higher micro-shear bond strength mean values than with self-adhesive resin cement. After aging sandblasting showed a statistically significant higher micro-shear bond strength mean values with adhesive resin cement, while hydrofluoric acid etching revealed a statistically non-significant higher values with adhesive resin cement than self-adhesive resin cement. Conclusion: For both surface treatments and resin cements aging had a detrimental effect on micro- shear bond strength.

Aim: The study aimed to evaluate and compare the effect of different surface treatment and thermocycling on the shear bond strength (SBS) of different dual-/light-cure cements bonding porcelain laminate veneers (PLV). Methods: One hundred and twenty A2 shade lithium disilicate discs were divided into three groups based on the resin cement used and on the pretreatment received and then divided into two subgroups: thermocycling and control. The surface treatment were either micro-etched with aluminium trioxide and 10% hydrofluoric acid or etched with 10% hydrofluoric acid only before cementation. Three dual-cure (Variolink Esthetic (I), RelyX Ultimate (II), and RelyX Unicem (III)) and three light-cure (Variolink Veneer (IV), Variolink Esthetic (V), RelyX Veneer (VI)) resin cements were used for cementation. The SBS of the samples was evaluated and analysed using three -way ANOVA with statistical significant set at α=0.05. Results: For all resin cements tested with different surface treatments, there was a statistically significant difference within resin cements per surface treatment (p<0.05). The shear bond strength in the micro-etch group was significant higher than the acid-etch group (p<0.05) There was statistically significant interaction observed between the surface treatment and thermocycling (p<0.05) as well as the cement and thermocycling(p<0.05). It was observed that the reduction in shear bond strength after thermocycling was more pronounced in the acid etch subgroup as compared to the microetch subgroup. However, the interaction between the three factors: surface treatments, thermocycling and resin cements did not demonstrate statistically significant differences between and within groups (p=0.087). Conclusions: Within the limitations of the present study, it acan be concluded that Dual cure resin cements showed a higher Shear bond strength as compared to light cure resin cements. Thermal cycling significantly decreased the shear bond strength for both ceramic surface treatments. After thermocycling, the specimens with 10% HF surface treatment showed lower shear bond strength values when compared to those treated by sandblasting with Al2O3 particles.

AbstractThe evolution of dental materials and the improvement of ceramic systems stimulated the increased use of Y-TZP zirconia-based ceramics. Despite the excellent mechanical performance, this material has low adhesion potential. The objective of this work was to evaluate the surface treatments and resin cements influence on bond strength between Y-TZP zirconia and composite resin interface. A total of 60 blocks of Y-TZP zirconia (3x8x8mm) were prepared and divided into 3 groups according to the surface treatments: (C) control - extra fine diamond bur, (J) sandblasting with Al2O3 and (JP) sandblasting with Al2O3 + ceramic primer. Each group was subdivided into two groups according to type of resin cement used for cementing composite resin discs (2mm thick x 5mm diameter): self-adhesive and conventional (n=10). The samples were stored in distilled water for 24 hours at 37±1°C in a incubator and subsequently submitted to the shear bond test to determine the bond strength (RU). There was no significant difference in RU among the  surface treatments when using conventional resin cement. For the self-adhesive resin cement, Al2O3 blasting and Al2O3 + primer blasting increased the RU but did not present significant differences between them (p<0.05). Comparing the cements, it was observed that regardless of the surface treatment, the highest values were for the self-adhesive resin cement (p<0.05). Application of the primer after blasting with Al2O3 did not increase RU. Keywords: Dental Prosthesis. Ceramics. Dental cements. Shear Strength.  ResumoA evolução dos materiais odontológicos e o aprimoramento dos sistemas cerâmicos impulsionaram o aumento da utilização da cerâmica a base de zircônia Y-TZP. Apesar do excelente desempenho mecânico, este material apresenta baixo potencial de adesão. O objetivo deste trabalho foi avaliar a influência dos tratamentos de superfícies e dos cimentos resinosos na resistência de união entre a interface zircônia Y-TZP e resina composta. Foram confeccionados 60 blocos de zircônia Y-TZP (3x8x8 mm) e divididos em 03 grupos de acordo com os tratamentos de superfícies que receberam: (C) controle - ponta diamantada extrafina, (J) jateamento com Al2O3 e (JP) jateamento com Al2O3 + primer cerâmico. Cada grupo foi subdividido em dois novos grupos de acordo com tipo de cimento resinoso utilizado para cimentação de discos de resina composta (2mm de espessura x 5mm de diâmetro): autoadesivo e resinoso convencional (n=10). As amostras foram armazenadas em água destilada por 24 horas a 37±1°C em estufa e posteriormente submetidas ao teste de cisalhamento para averiguar a resistência de união (RU). Não houve diferença significativa na RU entre os tratamentos de superfície quando utilizado o cimento resinoso convencional. Para o cimento resinoso autoadesivo o jateamento com Al2O3 e o jateamento de Al2O3 + primer aumentaram a RU porém não apresentaram diferenças significativas entre si (p<0,05). Comparando os cimentos observou-se que, independente do tratamento de superfície, os maiores valores foram para o cimento resinoso autoadesivo (p<0,05). A aplicação do primer após o jateamento com Al2O3 não proporcionou aumento da RU. Palavras-chave: Prótese Dentária. Cerâmica. Cimentos Dentários. Resistência ao Cisalhamento.

The purpose of this study was to evaluate the shear bond strength of composite resin to 4 different all-ceramic coping materials with 3 different surface treatments after thermocycling and without thermocycling. Three different surface treatments - sandblasting with 50 ㎛ alumina particles (AB); sandblasting with 50 ㎛ alumina particles and acid etching with 4% hydrofluoric acid (AE); sandblasting with 50 ㎛ alumina particles and 30 ㎛ alumina particles with tribochemical silica coating (SI) and silane application - were used on four different all-ceramic; Feldspatic ceramic (Duceram Plus); Lithium disilicate ceramic (IPS Empress2); Alumica ceramic (In-Ceram Alumina); Zirconia ceramic (Zi-Ceram) - substrates. Shear bond strength of restorative composite resin to substrate was tested after thermocycling and without thermocycling (n=10). Each specimen was subjected to a shear load at a crosshead speed of 2 ㎜/min until fracture. Two-way analysis of variance and Duncan multiple comparison test (α =0.05) were used to analyze the bond strength values. There were significant differences in the bond strengths for ceramic types (P<.001), surface treatments (P<.001), and thermocycling (P<.001). The Duncan analysis showed that the Si specimens had significantly higher bonding strengths than other specimens. The bond strength of composite resin decreased after thermocycling.

Abstract Objective The study aimed to evaluate the shear bond strength (SBS) of lithium disilicate glass-ceramic (LDGC) and resin cement (RC) using different surface treatments. Materials and Methods LDGC blocks (Vintage LD Press) were prepared, etched with 4.5% hydrofluoric acid, and randomly divided into seven groups (n = 10), depending on the surface treatments. The groups were divided as follows: 1) no surface treatment (control), 2) Silane Primer (KS), 3) Signum Ceramic Bond I (SGI), 4) Signum Ceramic Bond I/Signum Ceramic Bond II (SGI/SGII), 5) experimental silane (EXP), 6) experimental silane/Signum Ceramic Bond II (EXP/SGII), and 7) Experimental/Adper Scotchbond Multi-purpose Adhesive (EXP/ADP). The specimens were cemented to resin composite blocks with resin cement and stored in water at 37 °C for 24 hours. The specimens underwent 5,000 thermal cycles and were subjected to the SBS test. Mode of failure was evaluated under the stereo microscope. Statistical Analysis Data were analyzed with Welch ANOVA and Games-Howell post hoc tests (α = 0.05). Results The highest mean SBS showed in group EXP/ADP (45.49 ± 3.37 MPa); however, this was not significantly different from group EXP/SGII (41.38 ± 2.17 MPa) (p ≥ 0.05). The lowest SBS was shown in the control group (18.36 ± 0.69 MPa). This was not significantly different from group KS (20.17 ± 1.10 MPa) (p ≥ 0.05). Conclusions The different surface treatments significantly affected the SBS value between LDGC and RC. The application of pure silane coupling agent with or without the application of an adhesive improved the SBS value and bond quality.

Aim: This study evaluated the effect of surface treatments of yttria-stabilized tetragonal zirconia polycrystal (Y-TZP) ceramics on their bond strength to a resin cement. Methods: Seventy zirconia blocks (6 × 6 × 2 mm3, IPS e.max ZirCAD) were assigned into 7 groups (n=10) – as-sintered (AS), no treatment; tribochemical silica coating + silanization (TBS; Cojet-sand; ProSil); airabrasion with 45 μm alumina particles + universal primer (AAP; Monobond®Plus); fusion sputtering (FS); SiO2 nanofilm + silanization (SN; ProSil); FS+SN+ silanization (FSSN; ProSil); FS+SN+Universal Primer (FSSNP; Monobond®Plus). Afterwards, a resin cement (RelyX™ ARC) was applied inside cylinders (Ø = 0.96 mm × 1 mm height) placed on the zirconia surfaces. Microshear bond strength tests (μSBS) were carried out (1 mm/min). Failure and phase transformation analysis were performed. Bond strength data (MPa) were subjected to Kruskal-Wallis/Mann Whitney tests. Results: TBS (27 ± 1.2) and AAP (24.7 ± 0.8) showed higher bond strengths than the other groups, followed by FSSNP (15.5 ± 4.2) and FSSN (13.3 ± 3.6). FS (3.4 ± 0.44) and SN (9.5 ± 2.7) showed the lowest values (p < 0.001). Most of the specimens exhibited an adhesive failure. Conclusion: Air-abrasion by silica-coated alumina particles followed by silanization or by alumina particles followed by universal primer resulted in the highest resin bond strength to zirconia. Fusion sputtering and silica nanofilm deposition induced low strengths. However, when these methods are applied in combination and with a primer (FSSN and FSSNP), higher bond strengths may be achieved. Low bond strengths are obtained when no zirconia treatment is performed.

The purpose of this study was to evaluate the effect of non-thermal atmospheric pressure plasma (NTP) on shear bond strength (SBS) between yttria-stabilized tetragonal zirconia polycrystal (Y-TZP) and self-adhesive resin cement. For this study, surface energy (SE) was calculated with cube-shaped Y-TZP specimens, and SBS was measured on disc-shaped Y-TZP specimens bonded with G-CEM LinkAce or RelyX U200 resin cylinder. The Y-TZP specimens were classified into four groups according to the surface treatment as follows: Control (no surface treatment), NTP, Sb (Sandblasting), and Sb + NTP. The results showed that the SE was significantly higher in the NTP group than in the Control group (p < 0.05). For the SBS test, in non-thermocycling, the NTP group of both self-adhesive resin cements showed significantly higher SBS than the Control group (p < 0.05). However, regardless of the cement type in thermocycling, there was no significant increase in the SBS between the Control and NTP groups. Comparing the two cements, regardless of thermocycling, the NTP group of G-CEM LinkAce showed significantly higher SBS than that of RelyX U200 (p < 0.05). Our study suggests that NTP increases the SE. Furthermore, NTP increases the initial SBS, which is higher when using G-CEM LinkAce than when using RelyX U200.

Aim: The aim of this study was to evaluate the effect of calcium phosphate based desensitizing agent on shear bond strength of self-etch/adhesive resin cements to dentin. Materials and Methods: Eighty dentin specimens were prepared from freshly extracted human third molar teeth and were classified, randomly ( n = 20). Half of groups were treated with calcium phosphate based Teethmate Desensitizer and then Panavia V5, RelyX Ultimate (containing self-etch primer), Panavia SA, and RelyX U200 self-adhesive resin cements were luted to all dentin surfaces. All specimens were stored in an incubator at 37°C for 24 h. Shear bond strength was tested by a universal test machine at a 0.5 mm/min crosshead speed. The data were analyzed with a statistical program. Two-way ANOVA was used for statistical differences ( P <.05). Dentin surfaces were examined with scanning electron microscopy (SEM) at x5000 and x10000 magnifications. Results: The higher shear bond values were observed in the groups with Teethmate Desensitizer applied and cemented with self-etch (16.05 ± 6.24 and 14.73 ± 4.75), whereas the lowest bonding values were observed in the groups with self-adhesive resin cement without Teethmate Desensitizer (3.73 ± 0.77 and 5.85 ± 4.19; P <.001). As the main effect of the treatment, the bond strength was 9.39 ± 6.04 in the control group, whereas it was 13.49 ± 5.44 in the Teethmate applied groups ( P <.05) Conclusions: Calcium phosphate desensitizer did not adversely effected shear bond strength of self-etch/adhesive resin cements to dentin. It even significantly increased the shear bond strength of self-adhesive resin cements.
