“…In vitro studies also revealed that SU featured statistically similar mTBS when applied to dry or wet dentin by the ER mode, even after 1 year of in vitro storage in artificial saliva (13,14). In addition, results of clinical studies showed no significant difference in the performance of ER technique with SU on dry and wet dentin, since the authors found similar marginal adaptation and discoloration up to 36 months (1,15). According to the manufacturers, SU contains an ethanol-/water-based solvent system at 10 to 15% w/v (3M Data Sheet, 2016).…”

“…SU has a relatively high pH (2.7), being considered as an ultra-mild system, which has been shown to increase retention rates (19). A recent randomized clinical trial showed no significant difference when SU was applied to wet/dry dentin as ER or SE on non-carious cervical lesions, in terms of overall retention, marginal adaptation and staining after 36 months of clinical usage; however, when SU was used as an SE system with no selective etching of enamel, a significant difference was observed when baseline and 36-month evaluation periods were compared (15). In the present study, the negative performance of SU in the SE mode may have been influenced by the absence of enamel margin at the restoration.…”

Bond Strength and Cytotoxicity of a Universal Adhesive According to the Hybridization Strategies to Dentin

This study evaluated application protocol (etch-and-rinse/ER and self-etching/SE) and dentin wettability (wet and dry) on microtensile bond strength (mTBS) and transdentinal cytotoxicity of Scotchbond TM Universal (SU) adhesive system. The mTBS values and fracture mode were registered 24 h after adhesive system application and resin composite block build-up (n=5). For analysis of transdentinal cytotoxicity, odontoblast-like MDPC-23 cells were seeded on pulpal surface of dentin discs (0.4 mm thick) adapted to artificial pulp chambers (n=8). The adhesive system was applied to occlusal surface, followed by 24-h incubation time. Cell viability (Alamar Blue) and morphology (SEM) were assessed. Adper Single Bond 2 and Clearfil SE Bond were used as positive controls of the ER and SE application protocols, respectively. No treatment was performed on negative control (NC) group. Data were analyzed by ANOVA and Tukey's tests (α=5%). Higher mTBS values were found for ER mode in comparison with SE protocol (p<0.05). Dentin wettability had no effect on bond strength of SU in both the ER and SE techniques (p>0.05). Most fractures involved hybrid layer and/or adhesive layer. Neither variable prevented the intense toxic effects of adhesive systems on MDPC-23 cultured cells, since intense reduction in cell viability (±88%) and severe alterations in cell morphology were observed for all groups compared to NC, with no differences among them (p>0.05). Therefore, it was concluded that application of SU following the ER protocol had better adhesive performance. However, this adhesive system featured intense transdentinal cytotoxicity to pulp cells, regardless of application protocol and dentin wettability.

“…However, when the self-etch mode is performed a more superficial interaction might reduce the risk of post-operative sensitivity and delay the inevitable degradation phenomenon, as chemical interaction is likely to occur [4,129,135]. Concerning the enamel substrate, the literature suggests that selective etching prior to the application of a mild universal adhesive is an advisable strategy to optimize bonding [4,132,[135][136][137]. Nevertheless, the clinical use of phosphoric acid only on enamel margins without accidentally reaching dentin is challenging, especially if low-viscosity etchants are used.…”

Adhesives - Applications and Properties

View full text Add to dashboard Cite

Bonding agents play a crucial role in the effective sealing and retention of resin-based composite restorations, which have been increasingly placed and replaced by dentists in many countries around the world. In fact, direct adhesive restoration with composite resins has become the procedure of choice for the treatment of anterior and posterior teeth. However, long-term durability of those restorations may be compromised due to progressive loss of the integrity of adhesive interfaces. This means that no adhesive strategy is free from technique sensitivity. The specificity and proportion of different constitutive molecules, the interaction between them and substrates can differ greatly from one class of adhesive system to another, which can affect bond quality. Protocol simplification has been an inevitable trend that has boosted the use of self-etching and universal systems in adhesive dentistry. However, there is a lack of randomized clinical trials to prove the effectiveness of these systems. This chapter gives an overview of the most important issues in dental adhesion and adhesive systems, as well, discussing their composition and clinical use.

“…The results indicated that Filtek Supreme Ultra Universal Restorative (SU) exhibited moderate values and was therefore used as control in the study of Maruyama's group and in this study. Scotchbond Universal Adhesive (3M ESPE), a typical one-bottle all-in-one adhesive system utilized globally, was selected for this study due to its superior in vivo/ in vitro performance 13,[23][24][25][26] . In the present study, all cavities were pretreated with Scotchbond Universal Adhesive and then restored by a two-layered incremental technique.…”

Bonding of flowable resin composite restorations to class 1 occlusal cavities with and without cyclic load stress

2016

View full text Add to dashboard Cite

To examine the bonding of flowable resin composite restorations (F-restoration) to class 1 occlusal cavities with and without cyclic load stress, compared with that of a universal resin composite restoration (U-restoration). Two flowable composites and one universal composite (control) were applied with an adhesive system to 42 standardized class 1 occlusal cavities. The restored specimens were subjected to cyclic load stress and no stress modes. The microtensile bond strength (μ-TBS) of the dentin floor was measured. The U-restoration did not show pretesting failure. The F-restorations exhibited pretesting failure, regardless of the stress mode. The μ-TBS was not significantly different among the three restorations, regardless of the stress mode. The cyclic load stress did not influence the μ-TBS of the F-restorations; however, it significantly reduced μ-TBS in the U-restoration. The bonding reliability of the F-restorations was inferior to that of the U-restoration, for both stress modes.
