Representative scanning electron microscope images of the resin-enamel interface. The visible material is indicated by the abbreviation AL: adhesive layer.

Figure 5. Figure 6. Figure 7. Arrows indicate enamel fragments in adhesive layers. Figure 8. EL and AU did not contain nano-fillers Figures 6 and 7 but had distinct adhesive layers.

The adhesive layer of AU was largely homogeneous, with obvious inclusion of enamel fragments arrows in Figure 7. Conversely, PE possessed a clear honeycomb network without enamel fragments Figure 6.

Manufacturers of universal adhesives have claimed that there is no compromise in bonding performance when either total-etch or self-etch modes are used.

If true, this would allow the use of multiple modes in the same restoration. This, in turn, would allow clinicians to adapt appropriately to heterogeneous substrates, which would improve bond durability and reduce postoperative sensitivity.

Similarly, when a single mode must be used for the whole of a small restoration, any heterogeneity of the substrate should not have a negative effect.

This should have clinical benefits. However, there is concern that the technology of universal adhesives may not offer a genuine advantage when compared with previous generations of single-step self-etch adhesives.

However, there is minimal information regarding the influence of different application modes on the durability of the bond to tooth substrates.

Therefore, to clarify the bonding performance of universal adhesives, enamel bond durability was evaluated through fatigue testing.

However, in total-etch mode, there were no significant differences among the adhesives in SBS. The reason that AU demonstrated a lower SBS value in self-etch mode is thought to be related to it having a lower etching capability than other universal adhesives.

Therefore, the lower acidity of AU might not allow for strong micromechanical retention, leading to a lower SBS value.

There were no significant differences among all adhesives in SFS, although values in self-etch mode were significantly lower than in total-etch mode.

In particular, none of the universal adhesives differed from the conventional single-step self-etch adhesive SP. Therefore, the null hypothesis that universal adhesives would not differ from conventional single-step self-etch adhesives with respect to bond durability was not rejected.

However, the other null hypothesis that phosphoric acid pre-etching would not affect the enamel bond durability of universal adhesives was rejected.

The durability of bonded interfaces is threatened by many factors, such as biofilm attack, hydrolytic degradation of the adhesive, and fatigue of the adhesives.

Therefore, the process of enamel bond degradation is simpler than that of dentin bonds due to the absence of collagen fibrils. Hence, deterioration of the adhesive layer in enamel bonds may directly lead to failure of the bond itself, indicating that the composition and properties of the adhesive layer are the primary factors in enamel bond durability.

Fatigue can be defined as the degradation or failure of mechanical properties after repeated subcritical stress at a level below the ultimate fracture strength of the material or interface.

When considering long-term bond durability, the degradation mechanism of the resin-tooth interface is extremely important.

Although no clinical conclusions can be drawn from this difference because it is not significant, the compositions of the adhesives suggest that these differences may be valid and worthy of further investigation.

This thicker adhesive layer may behave as a shock absorber and the presence of nano-filler may inhibit crack propagation.

In addition, the thicker adhesive layer may decrease the relative importance of the oxygen inhibition layer, which is thought to be a vulnerable site.

Bond strength to phosphoric acid—etched enamel is mainly attributable to the penetration of adhesives into the enamel crystals and rods. From the SEM observations of enamel-resin interfaces in self-etch mode, gaps between enamel crystals and rods were not found in any adhesive.

However, in total-etch mode, spicular etching patterns and penetration of resin tags were clearly observed for all adhesives. In addition, from the SFS results, total-etch mode significantly increased the enamel bond durability of universal adhesives compared with self-etch mode.

Therefore, creating micromechanical retention on the enamel surface through phosphoric acid pre-etching may contribute to better resistance of long-term biomechanical loads when using universal adhesives.

Regarding dentin bonding, we evaluated the influence of different etching modes on the dentin bond durability of three universal adhesives using the same fatigue testing method as the present study.

In contrast, the SBS and SFS of the universal adhesives showed equivalent bonding quality to dentin regardless of etching mode, although the dentin bond quality of the universal adhesives did vary among adhesives.

We concluded that using universal adhesives in total-etch mode does not have a negative impact on dentin bond quality. However, postoperative sensitivity arises from a different mechanism from bond strength, and increased etching of dentin in the total-etch mode may increase it.

This is an important topic for further work. The clinical implication of this study is that universal adhesives should be used with phosphoric acid pre-etching of enamel, as with the previous generation of single-step self-etch adhesives.

In clinical situations, the adherent surface of mineralized tooth tissue is dependent on the cavity configuration. Given that there is no compromise in bonding performance when either total-etch or self-etch mode is used with dentin, total-etch or selective-etch mode should be chosen to achieve a reliable bond to the enamel substrate.

In particular, if the cavity is too small to precisely manipulate the phosphoric acid agent for selective etching, the total-etch approach with universal adhesives is most likely appropriate.

Within the limitations of this in vitro study, although AU demonstrated a significantly lower SBS value than the other tested adhesives in self-etch mode, there were no significant differences among the adhesives in both SBS and SFS in total-etch mode and in SFS in self-etch mode.

SEM observations of resin-enamel interfaces revealed that the resin tags in enamel surfaces were longer for the samples in total-etch mode than those in self-etch mode.

In addition, the thickness and characteristics of the adhesive layers were dependent on the adhesive. All tested adhesives showed significantly higher values in total-etch mode than in self-etch mode.

Therefore, for universal adhesives, total-etch mode has a positive effect on the enamel bond durability, as with the previous generation of single-step adhesives.

This study was conducted in accordance with all the provisions of the local human subjects oversight committee guidelines and policies of Nihon University School of Dentistry.
