“…In terms of the SE strategy, no significant difference in mTBS was observed between wet and dry dentin. It was also observed that SE bonding featured significantly lower bond strength values than did ER for all tested application protocols, as previously shown (13). Therefore, the null hypothesis of this study was rejected for mTBS analysis, since the application protocol played a significant role in the bonding performance of SU to dentin.…”

“…Also, the smear layer is considered a physical barrier for monomer infiltration to obtain an integrated hybrid layer (21). Regarding the analysis of the fracture mode, most fractures involved the hybrid layer and/or the adhesive layer, as observed in previous studies (13,14). This suggests that hybrid layer was effectively formed after application of adhesive systems in all experimental conditions; nevertheless, concentration of tensions at this interface lead to fracture (22).…”

“…According to our results, the application of SU to both wet and dry dentin surfaces by the ER technique resulted in the highest immediate mTBS values, with no significant difference relative to the conventional ER adhesive system Adper TM Single Bond 2 (ASB; 3M ESPE). 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).…”

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.

“…154,155,156 The pH of self-etch and self-adhesive materials directly relates to their reduced potential, as compared to that of phosphoric acid, 157,158 to etch the highly-mineralized enamel. 25,155,156,157,159,160,161,162,163,164 Hence, increasing its surface area and creating deep etch-pits remains important for the achievement of an effective and durable bond to enamel. 4,165,166,167,168 According to the buffering capacity that such substrate offers to the action of self-etch systems in general, it can be expected that they do have a lower demineralizing effect on the hydroxyapatite-rich enamel, which ultimately compromise their bonding effectiveness.…”

Bonding efficiency and durability: current possibilities

et al. 2017

Bonding plays a major role in dentistry nowadays. Dental adhesives are used in association with composites to solve many restorative issues. However, the wide variety of bonding agents currently available makes it difficult for clinicians to choose the best alternative in terms of material and technique, especially when different clinical situations are considered. Moreover, although bonding agents allow for a more conservative restorative approach, achieving a durable adhesive interface remains a matter of concern, and this mainly due to degradation of the bonding complex in the challenging oral environment. This review aims to present strategies that are being used or those still in development which may help to prevent degradation. It is fundamental that professionals are aware of these strategies to counteract degradation as much as possible. None of them are efficient to completely solve this problem, but they certainly represent reasonable alternatives to increase the lifetime of adhesive restorations.

“…According to the manufacturers, these products can be used reliably in selective-enamel etch mode, in total-etch strategy to dentin and enamel or in self-etch mode to dentin, making them more attractive to the clinician and reducing the sensitivity of the application technique (13).…”

Bonding Effectiveness of Universal Adhesive to Intracoronal Bleached Dentin Treated with Sodium Ascorbate

et al. 2016

This study evaluated the effect of restorative protocol with sodium ascorbate on the shear bond strength (SBS) of a universal adhesive to intracoronal bleached dentin. One hundred-and-twenty bovine dentin fragments were randomly divided into 12 groups (n=10), according to the bleaching procedure (unbleached and bleached) and restorative protocol (no treatment, 10% sodium ascorbate -10SA, 35% sodium ascorbate -35SA and two-step etch-and-rinse -ER or one-step self-etch -SE Scotchbond universal adhesive approaches). Four whitening sessions were performed using 35% hydrogen peroxide. The samples from control groups were kept in relative humidity at 37 °C. Immediately after bleaching procedures, the assigned antioxidant solution was applied on dentin and restorative procedures were performed following either the ER or the SE approach. After 24 h, the specimens were subjected to SBS test. Data (MPa) were analyzed by ANOVA and Tukey's test (α=0.05). Lower SBS values were found for bleached specimens (8.54 MPa) compared with those unbleached (12.13 MPa) (p<0.05). The bond strength of the sodium ascorbate-treated groups was higher than those untreated, regardless of the strategy employed (p<0.05). Groups restored without sodium ascorbate showed lower bond strength values for both ER (8.32 MPa) and SE (8.28 MPa) adhesive strategies. The group treated with 10SA submitted to ER approach (10.14 MPa) was similar to untreated groups (p>0.05). It may be concluded that bond strength of composite resin to intracoronal dentin was affected by restorative protocol and reduced by bleaching.
