“…There are conflicting results between the studies in terms of contribution to bond strength. Although some studies indicated that they increase (39) or decrease (36,40) bonding strength, some studies have not found any significant effect (26,41). In the present study, while acid treatment with the bonding agent decreased the bonding strength between the composites, it improved the bonding strength between the RMGIC and the RBC.…”

Aim: To assess the bonding strength of the Equia Forte resin modified glass ionomer cement to the hybrid composite material by applying different surface treatments. Methodology: 140 samples as 70 Equia Forte and 70 G-eanial composites were produced as 8 mm diameter 3 mm high cylindrical standardized samples. The samples were divided into 7 groups to treat surfaces. G-eanial composite resins as 4 mm diameter 3 mm high was placed onto the samples and polymerized. Then 1000 thermal cycle was applied and samples were mounted in the universal testing machine. Obtained bond strength values were recorded as Newton. One way Anova and Scheffe post hoc tests were performed for statistics. Results: In the G-aenial group, the highest bond strength was obtained with laser-bond method (N=17.71, P<0.05) and the lowest bonding strength was obtained with only laser-treated method (N=3.45, P<0.05). In the Equia group, the highest bond strength was obtained with air abrasion-bond method (N=9.29, P<0.05) and the lowest bonding strength was obtained with only laser-treated method (N=0.00, P<0.05). Conclusion: The fact that sufficient bond strength could not be reached by any surface treatment in Equia Forte may suggest that replacing the Equia Forte instead of repairs may be a better choice.

“…Composite repair often presents a different challenge, especially because the surface of aged composites lacks any unreacted double bonds available for bonding to the new composite 10,11) . Although there is no laboratorial aging protocol considered as gold standard that simulates this phenomenon, some authors have followed the principle that 10,000 cycles correspond to one year of physiological aging in the oral cavity 8) , what would be enough to promote a considerable increase in the double bond conversion of composite materials.…”

Repair bond strength of bulk-fill resin composite: Effect of different adhesive protocols

et al. 2020

This study evaluated the effect of different adhesive protocols on the shear bond strength (SBS) of bulk-fill resin composite repaired with bulk-fill or conventional composite. Cylindrical bulk-fill resin composite specimens were prepared and allocated into groups according to the bonding strategy: no treatment, Silane+Scotch Bond Multipurpose (S+SBMP), Tetric N Bond Universal, and Single Bond Universal. Following bonding strategy, bulk-fill or conventional composite buildups were performed. After 24 h of storage in distilled water at 37°C, shear force was applied to the interface using a universal testing machine. The data were analyzed by twoway ANOVA and Tukey test (α=0.05). SBS was influenced by the bonding strategy and the composite used (p<0.001). Irrespective of the composite used, the group S+SBMP yielded the highest SBS values (p<0.001). Repair bond strength of bulk-fill composites can be improved by using a silane coupling agent followed by a hydrophobic resin.

“…Although phosphoric acid is not capable of modifying the surface topography, 11 it has a cleansing effect, eliminates the surface debris and enhances surface energy and wettability of the surface. 11,36 The subsequent application of a silane coupling agent might have improved the union between the surface of the hybrid ceramic and the resin cement. It can be assumed that adequate surface activation was provided through silanization and chemical interaction rather than micromechanical bonding.…”

In vitro evaluation of the effect of different surface treatments of a hybrid ceramic on the microtensile bond strength to a luting resin cement. Abstract Introduction:The aim of the present study was to investigate the effect of different surface treatments of a hybrid ceramic, Vita Enamic, on the micro-tensile bond strength (µ-TBS) to resin cement. Methods: Ten blocks (3×10×8 mm) were retrieved from the original blocks and divided into 5 groups according to the different surface treatments performed: Groups 1: 35% acid phosphoric for 60 seconds (PA); group 2: Sandblasting with 50 µm Al 2 O 3 particles for 10 seconds (SB); groups 3: 9.5% hydrofluoric acid for 60 seconds (HF), group 4: The Er:YAG laser (2 W, 10 Hz) (ER1), group 5: The Er:YAG laser (3 W, 10 Hz) (ER2). All treated surfaces were salinized and the blocks with similar surface treatments were bonded together using a dual-cured resin cement and light-cured. After 24-hour storage in water, the blocks were cut into beams (1 mm 2 ). Half of the specimens in each group (n=16) were tested immediately and the rest were subjected to thermocycling between 5°C and 55°C for 6000 cycles before the µ-TBS test at a crosshead speed of 0.5 mm/min. The data were analyzed using two-way analysis of variance (ANOVA) and Tukey HSD tests and the significance level was set at 0.05. The failure mode was evaluated by using a stereomicroscope. Results: The µ-TBS was clearly influenced by surface treatment methods (P < 0.001) and thermocycling significantly decreased the bond strength values in all groups (P = 0.007). The highest value (66.07 MPa ± 11.3) was obtained for the HF groups with no thermocycling and the lowest values were observed in the laser groups with no significant difference among different irradiation parameters. Adhesive failure was mainly observed in the PA and SB groups while mixed failure was predominantly shown in the laser and HF groups. Conclusion: This study demonstrated that surface treatment of VE with HF and salinization could improve the bond strength to a dual-cured resin cement, and Er:YAG laser irradiation with the evaluated parameters did not promote the adhesion of the resin cement to VE.
