“…On the other hand, there was no difference between Clearfil and Single Bond total-etch system in enamel. Another work (17) found higher bond strength to dentin with Prime&Bond NT/NRC than that of the present study, as well as similar bond strength for Prime&Bond NT/NRC and Single Bond, and similar incidence of adhesive failures for both systems. In the present study, most tested systems showed a large number of mixed failures in enamel and cohesive in dentin, except for All Bond 2, which showed adhesive failures in both substrates, as published elsewhere (18).…”

The aim of this study was to assess the tensile bond strength of four adhesive systems to enamel and dentin: Clearfil Liner Bond 2V -C, Prime&Bond NT/NRC -PB, Single Bond -SB and All Bond 2 -AB. For such purpose, 40 sound human molars were selected. Crowns were bisected in a mesiodistal direction and each half was ground until flat enamel (E) or dentin (D) surfaces were obtained. A total of 80 specimens were randomly assigned to 4 groups (n=20, 10 in enamel and 10 in dentin). After surface treatment, a composite resin (Z250; 3M) cone was prepared using a split Teflon ® matrix. Bond strength was tested in an universal testing machine (0. . Statistical analysis of data by two-way ANOVA showed that C presented the best results followed by SB. In conclusion, among the tested materials, Clearfil Liner Bond 2V self-etching primer adhesive syetem had the best performance. The substrate type influenced bond strength, being higher to enamel.

“…[4][5][6] Primary dentin has been assumed to be different from permanent dentin due to the variable amounts of mineral components, as well as morphological and structural differences. There might be substantial differences in the properties of primary dentin compared to permanent dentin.…”

Single-step self-etch systems are capable of producing a predictable bond to primary dentin, although the bond strength was found to be lower than permanent dentin. SUMMARYCurrently, there is little information regarding the bonding efficacy of single-step self-etch systems to primary tooth dentin. This study examined the microtensile bond strength of single-step self-etch systems (Clearfil tri-S Bond and One-Up Bond F Plus) to sound primary and permanent tooth dentin. Adhesives were applied to flat samples of primary and permanent tooth dentin, and resin composites were bonded according to the manufacturers' instructions. After 24 hours of storage in distilled water at 37°C, hour glass-shaped specimens were produced. They were subjected to microtensile testing at a crosshead speed of 1.0 mm/minute. The results were analyzed using 2-way analysis of variance (ANOVA) followed by the Tukey HSD post-hoc test (α α=0.05). Field-emission scanning electron microscopy (FE-SEM) observations of the adhesive-treated dentin surfaces and the resin/dentin interface were also conducted. The bond strengths of primary tooth dentin were significantly lower than that of permanent tooth dentin for both self-etch systems: 44.7 ± 10.4 versus 54.3 ± 9.0 MPa for Clearfil tri-S Bond and 40.6 ± 9.9 versus 50.0 ± 8.7 MPa for One-Up Bond F Plus (p<0.001). There was no statistically significant interaction between the type of adhesive system and the dentin substrate (p=0.957). Although there was no statistically significant difference in the mean values among the different adhesive systems (p=0.094), there was a statistically significant difference in mean values among the different dentin substrates (p<0.001), which were lower for primary tooth dentin than for permanent tooth Operative Dentistry dentin. The failure modes were also independent of the type of dentin but dependent on the adhesive systems, an equal distribution among the 3 types of failure for Clearfil tri-S Bond and cohesive failures in adhesives for One-Up Bond F Plus. FE-SEM observations of dentin to which adhesive had been applied revealed that the smear layer had been removed and the collagen fibers exposed. Though the bond strengths to primary tooth dentin were lower than to permanent tooth dentin, excellent adaptation of the single-step selfetch systems to both dentin substrates was observed by FE-SEM. Further studies are required to determine the long-term clinical performance of these adhesive systems when applied to primary tooth dentin.

“…Regarding restorative materials, microhybrid and flowable composite resins demonstrated higher bond strength when compared with RMGICs. The adhesion process of GICs is by chemical bonding between the carboxylic polyacids from material, which are chelating agents, and calcium ions from tooth (20). Nevertheless, GIC's bond strength is considered low, since chemical adhesion is lower than mechanical adhesion to tooth structure (21) by means of the hybrid layer, as occurs in resin materials.…”

“…Although RMGIC presents chemical and also micromechanical adhesion to dentin structure (22), it is speculated that the mechanical component is lower than the one found in the composites, and this aspect seems to be insufficient to provide similar adhesion among them (21). Another aspect that may have contributed to the lower bond strength of the RMGIC is the possible presence of bubbles, which is very frequent (20). Bubbles along the interface between dentine and RMGIC allow an uneven stress concentration that may lead to failure in adhesion (21).…”

Impact of Intracoronal Dentin Treatment Prior to Bleaching on Bond Strength of Restorative Materials

Surface treatment of dentin before the bleaching procedure may affect its permeability and influence the bond strength of restorative materials. This study evaluated the influence of surface treatment before the bleaching on shear bond strength (SBT) of restorative materials to intracoronal dentin. Dentin slabs were subjected to surface treatment: no bleaching (control -CON), no surface treatment + bleaching (HP), 37% phosphoric acid + bleaching (PA) and Er:YAG laser + bleaching (L). After the bleaching procedure, specimens (n=10) were restored with: microhybrid composite resin (MH), flowable composite resin (F), and resin-modified glass-ionomer cement (RMGIC). The shear test was carried out. ANOVA and Tukey's test (α=0.05) showed significant difference for surface treatment and restorative materials (p<0.05). CON presented higher STB and was statistically different from HP (p<0.05). PA and L showed intermediate values and were statistically similar to CON and HP (p>0.05). STB for MH and F were higher than RMGIC (p<0.05), and did not differ from each other (p>0.05). The surface treatments with phosphoric acid and Er:YAG laser before the bleaching procedure provided shear bond strength at the same level of unbleached dentin and the composite resins presented superior bond strength to the intracoronal dentin.
