“…Scotchbond Universal Adhesive (3M Oral Care, St. Paul, MN, USA) was the first universal adhesive introduced commercially in Japan in November of 2012. Later, universal adhesives which could be of use with resin luting cements [2], various substrates without surface treatment [3], reduced treatment times [4], or various surface moisture of enamel and dentin surfaces [5] were introduced in the market. Despite this exciting flexibility, some reports suggest that the bond durability of numerous universal adhesives is inferior to that of the two-step self-etch adhesives.…”

In this study, dentin bond fatigue resistance and interfacial science characteristics of universal adhesives through etch-and-rinse and self-etch modes were investigated. Resin composite was bonded to human dentin with four universal adhesives, namely, Adhese Universal, All-Bond Universal, G-Premio Bond, and Scotchbond Universal Adhesive. The initial bond strengths, bond fatigue strengths, and interfacial science characteristics of the universal adhesives with dentin through etch-and-rinse and self-etch modes were determined. Bond fatigue resistance (initial bond strength and bond fatigue strength) of universal adhesives in etch-and-rinse mode showed no significant difference in contrast to that in self-etch mode and was material-dependent regardless of the etching mode. Although phosphoric acid conditioning of dentin did not have a strong impact on the bond fatigue resistance, surface free energy and parameters of dentin were significantly decreased by etching and by application of universal adhesives regardless of etching mode. Changes in γ S and γ S h for when universal adhesive was applied to etched and ground dentin were significantly different depending on the adhesive. The results suggest that bonding performance of universal adhesives was effective in both etching modes; however, bonding mechanisms may be different for each. Keywords; light-curing of dental adhesives, dental debonding, dental etching, dental restoration failure, dental stress analysis Materials and Methods Study materials Four universal adhesives were used in this study: (i) Adhese Universal (AU, Ivoclar Vivadent, Schaan, Liechtenstein), (ii) All-Bond Universal (AB, Bisco, Schaumburg, IL, USA), (iii) G-Premio Bond (GB, GC, Tokyo, Japan), and (iv) Scotchbond Universal Adhesive (SU, 3M Oral Care). Ultra-Etch (Ultradent, South Jordan, UT, USA) was used as a 35% phosphoric acid pre-etching agent and Z100 Restorative (3M Oral Care) as the resin composite employed to make specimens. Table 1 lists the tested materials and their lot numbers and components. Specimen preparation This study used de-identified extracted human molar teeth. To comply with research ethics, the protocol was reviewed and approved by the Ethics Committee for Human Studies of NU (#2015-06) and Biomedical Institutional Review Board at CU (#760765-1). Preparation of the teeth was done in the manner described in the study by Nagura et al. [18], except that a flat dentin surface, rather than enamel surface, was prepared. Specimens with and without etching were prepared for each adhesive, giving a total of eight experimental groups for each of the procedures performed (Table 2). Initial bond strength testing Initial bond strength testing was carried out as described by Nagura et al. [18]. Bond fatigue strength testing Bond fatigue strength testing was carried out as described by Nagura et al. [18].

“…Since high retention is obtained from the proper bond, it enhances marginal adaptation, reduces microleakage, and improves fracture resistance (Janda et al, 2007). Advancement of dental technology is associated with different efforts to initiate adhesion of the luting cement to the inner side of metal restorations (Tsujimoto et al, 2018). This would be useful to achieve durable retention of the restoration, particularly, when there is a shortness of the crown and/or tapering caused by preparation (Abreu et al, 2009).…”

ObjectiveTo evaluate the effect of different surface treatments of nickel chrome (NiCr) with the type of metal primer monomers on the conventional tensile bond strength (CTBS) of resin cement.MethodsForty disks of NiCr alloy were prepared for CTBS test and grouped as follows: group (1) no surface treatment (control group), group (2) oxide layer only, group (3) air abrasion, and group (4) air abrasion with an oxide layer. Each main group was subdivided into two subgroups (n = 5) depending upon the type of metal primer used for metal treatment. All specimens were bonded with resin cements. The CTBS was tested using a tensile testing machine. The data were statistically analyzed with One-way ANOVA, Two-way ANOVA, and T-test at 0.05 level of significance.ResultsSignificant differences in the mean value of the CTBS between different surface treatments (P ≤ 0.05) were observed. Tukey's test showed that air abrasion surface treatment had the highest mean value followed by the air abrasion with an oxide layer and oxide layer only. The control group showed the lowest value of significant difference compared to all treated groups (P ≤ 0.05).ConclusionsCTBS of self-adhesive resin cement to NiCr is dependent on surface treatment. Two types of the metal primer of different monomer contents 10-methacryloyloxydecyldihydrogenphosphate (MDP) or Thiophosphoricmethacrylate (MEPS) show similar behavior on the tensile bond strength.

“…A recent trend in simplified and streamlined adhesives has been the utilization of universal adhesives, which can be used in etch‐and‐rinse or self‐etch modes Scotchbond Universal Adhesive (3M Oral Care) was launched in 2012 as the first commercial universal adhesive. Other manufacturers later released similar universal adhesives with various distinctive characteristics, such as use with resin luting cement , use with various substrates , or shortened application times . It has also been reported that the bond durability of most universal adhesives to enamel in etch‐and‐rinse and self‐etch modes and to dentin in self‐etch mode is lower than that of two‐step self‐etch adhesives.…”

The purpose of this study was to evaluate whether surface wetness would influence the bonding effectiveness of universal adhesives in etch‐and‐rinse mode. All‐Bond Universal (AB), G‐Premio Bond (GP), Prime & Bond Active (PB), and Scotchbond Universal Adhesive (SU) were evaluated. Initial bond strengths and bond‐fatigue strengths of universal adhesives to both wet and dry enamel and dentin in etch‐and‐rinse mode were determined. Scanning electron microscopy observations of the adhesive interfaces were also conducted. The bond‐fatigue durability of universal adhesive to enamel in etch‐and‐rinse mode was influenced by the surface wetness, unlike that to dentin. The bond fatigue durability of AB and GP to dentin in etch‐and‐rinse mode was different depending on the surface wetness, unlike that of PB and SU. The thicknesses of the adhesive or hybrid layer of resin–dentin interfaces were not influenced by the surface wetness, but the length of resin tags in the wet group was longer than in the dry group. Some universal adhesives with the addition of specific components and optimization of water content can achieve stable bonds regardless of surface wetness, but the surface wetness of dentin is still a significant factor for universal adhesive bonding in etch‐and rinse mode, unlike that of enamel.
