“…Because of this, a few simplified protocols were presented by using a two-concentration sequence or only one single solution of absolute ethanol to accomplish the process [83][84][85]. Nonetheless, no clinical study has confirmed the superiority of the EWB technique compared to the WWB technique [87,88].…”

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.

“…17,35 However, clinical trials evaluating the EWBT did not show significant differences after 12 or 18 months, with retention rates for the EWBT at 91.67% and 93.55%. 16,36 Technique differences in those studies are related to the use of a formulated hydrophobic primer (hydrophobic bond diluted in ethanol in a concentration of 10% or 50 w% ethanol) or the ethanol not being actively applied. 12,15,16,36,37 Although no differences were detected when compared with the control groups, one study reported that the 91.7% success for the EWBT in comparison with the 100% success rate for the control could be related to the sensitivity of the EWBT.…”

“…The viscosity of the hydrophobic adhesive may have restricted monomer infiltration into the demineralized dentin, as studies using diluted hydrophobic monomers for application resulted in improved clinical success rates. 15,36 The present study used commercially available hydrophobic monomers with the EWBT. Clinicians do not have access to diluted hydrophobic monomers, and the in vitro or in vivo results reported previously might not be reproducible as they depend on experimental materials.…”

This double-blind randomized controlled clinical trial evaluated the effectiveness of dentin pretreatment with 100% ethanol (EWBT-ethanol wet bonding technique) and different adhesive protocols in noncarious cervical lesions (NCCL) after 6 months. Patients presenting at least one NCCL were included. NCCLs (n=148) were randomly assigned to 4 groups: NE (Non-EWBT + three-step etch-and-rinse (Scotchbond Multi Purpose, 3M ESPE [MP]), E (EWBT + MP); EB (EWBT + [Bondthird step of MP]), and EU (EWBT + universal adhesive (Single Bond Universal, 3M ESPE). Conventional acid-etching (Condac 37%, FGM) and nanohybrid resin composite (Z350, 3M ESPE) were used. Trained and calibrated examiners (Kappa = 0.61) evaluated the restorations at baseline (7 days) and 6-month recall using the USPHS modified criteria. Data were subjected to Chi square (α = 0.05). Differences in the success rate were found for the treatments (p = 0.003). EB presented the lowest success rate compared with the other groups (p < 0.02). No significant differences were detected among NE, E, and EU (p > 0.49). The survival rates were 97.23%, 97.30%, 78.95%, and 97.30% for NE, E, EB, and EU, respectively. Regarding postoperative sensitivity, a significant reduction was found for groups E (p = 0.027) and EU (p < 0.01) after 6 months. After 6 months, EWBT associated to the hydrophobic adhesive system had the highest failure rate.

Self-etching adhesive (SEA) systems were recently introduced to simplify the bonding procedure, reducing the number of operative steps, and were initially considered a good replacement for the etch-and-rinse adhesive system that uses orthophosphoric acid (H₃PO₄) (PA) for enamel and dentin etching [1]. However, the recent literature underlines that the effectiveness of the enamel bonding with SEA is questionable [2]. This technique in fact provides a bond strength of compos- AbstractBackground. Self-etching adhesive (SEA) systems were recently introduced to simplify the bonding procedure and were initially considered a good replacement for the etch-and-rinse adhesive system that uses orthophosphoric acid (PA) for enamel and dentin etching. Siloranes, a new class of ring opening monomers, were synthesized to overcome the problems related to polymerization shrinkage. This new type of monomer is obtained from the reaction of oxirane and silorane molecules with a volumetric shrinkage determined to be 0.99%. Objectives. To assess the influence of preliminary phosphoric acid etching on the sealing ability of silorane-and methacrylate-based composites. Material and methods. Standard class V cavities were prepared on the buccal side of 48 extracted, sound, human premolars. The specimens were randomly divided in two groups: A) Silorane System ® /Filtek Silorane ® ; B) Scotchbond Universal ® /Filtek Supreme ® . Each group was divided in two subgroups. A1) and B1): no preetching was performed. A2) and B2): selective, enamel pre-etching was performed. The interfacial sealing ability of the materials was evaluated by scoring the depth of methylene blue penetration through optical microscope observations. The differences in infiltration scores recorded for the tested materials were evaluated for statistical significance (Kruskal-Wallis ANOVA, Mann-Whitney U test, p < 0.05).Results. No groups showed a "0" score, and group B2 had the lowest individual score, reaching at least a "2" score.In the silorane groups, pre-etching decreased the infiltration score but the result was not statistically significant. No statistically significant differences emerged among the tested materials except for the Bis-GMA composite restored group where the pre-etching significantly reduced the interfacial leakage (p < 0.05).Conclusions. Selective enamel pre-etching significantly reduced the marginal infiltration in class V cavities, restored with Bis-GMA composite and a self-etching adhesive system. The low-shrinking silorane composite achieved better sealing ability (Dent. Med. Probl. 2016, 53, 3, 365-372).
