“…However, a recently introduced UA, not included in the previously mentioned study, contains additional silane coupling agents ([i.e., 3-(aminopropyl) triethoxysilane and γ-methacrylo xypropyltriethoxysilane; Table 1) that are more stable in an aqueous acidic environment. This adhesive achieved better results in bonding to glass-ceramics compared to its predecessor (Yao et al 2021), with another benefit of being BPA (bisphenol A)-derivate free since it does not contain bisphenol A-diglycidylmethacrylate (Bis-GMA) (patent literature). Also, the chemical interaction and antagonistic effect between silane agents and 10-MDP must also be taken into consideration as the former can cause hydroxylation of zirconia and, consequently, alter the adsorption of 10-MDP, thus highlighting the importance of optimizing the percentage of silane incorporated within UAs (Ye et al 2022).…”

There have been significant advances in adhesive dentistry in recent decades, with efforts being made to improve the mechanical and bonding properties of resin-based dental adhesive materials. Various attempts have been made to achieve versatility, introducing functional monomers and silanes into the materials’ composition to enable the chemical reaction with tooth structure and restorative materials and a multimode use. The novel adhesive materials also tend to be simpler in terms of clinical use, requiring reduced number of steps, making them less technique sensitive. However, these materials must also be reliable and have a long-lasting bond with different substrates. In order to fulfill these arduous tasks, different chemical constituents and different techniques are continuously being developed and introduced into dental adhesive materials. This critical review aims to discuss the concepts behind novel monomers, bioactive molecules, and alternative techniques recently implemented in adhesive dentistry. Incorporating monomers that are more resistant to hydrolytic degradation and functional monomers that enhance the micromechanical retention and improve chemical interactions between adhesive resin materials and various substrates improved the performance of adhesive materials. The current trend is to blend bioactive molecules into adhesive materials to enhance the mechanical properties and prevent endogenous enzymatic degradation of the dental substrate, thus ensuring the longevity of resin–dentin bonds. Moreover, alternative etching materials and techniques have been developed to address the drawbacks of phosphoric acid dentin etching. Altogether, we are witnessing a dynamic era in adhesive dentistry, with advancements aiming to bring us closer to simple and reliable bonding. However, simplification and novelty should not be achieved at the expense of material properties.

“…24 Some authors indicated that a universal adhesive containing silane has improved or decreased the bond strength associated with the type of silane in the universal adhesive. 25,26 In this study, the SBU group (27.50 AE 2.31 MPa) has a significantly lower SBS compared to the SBP group (33.24 AE 3.66 MPa). The silane agent is present in both SBU and SBP.…”

Objective This study investigates the effect of different chemical surface treatment protocols with different functional monomers of universal adhesives on the shear bond strength between resin-matrix ceramic and resin composite. Materials and Methods Eighty resin-matrix ceramics (Shofu block HC) were built and designed into eight groups of ten specimens and surface treated with HC primer (HC) and/or three universal adhesives (single bond universal [SBU], Scotchbond universal plus [SBP], and Tetric N-bond universal [TNU]) assigning follows; group 1, nonsurface treated; group 2, HC; group 3, SBU; group 4, HC + SBU; group 5, SBP; group 6, HC + SBP; group 7, TNU; group 8, HC + TNU. A template was put on the specimen center, and then pushed packable resin composite. Mechanical testing machinery was used to examine the samples' shear bond strength (SBS) values. To examine failure patterns, the debonded specimen surfaces were examined by a stereomicroscope. Statistical Analysis The one-way analysis of variance method was used to evaluate the data, and the Tukey's test was used to determine the significant level (p < 0.05). Results The highest SBS was obtained in group 6 (39.25 ± 1.65 MPa). Group 1 (4.15 ± 0.54 MPa) had the lowest SBS. Group 6 exhibited the highest percentage of cohesive failure patterns (70%). High SBS values were frequently correlated with the surface treatment groups and the cohesive failure patterns. Conclusion The application of HC primer prior to the universal adhesive is an alternative protocol for enhancing the repair bond strength between resin-matrix ceramic and resin composite interfaces. Moreover, the application of HC primer prior to the SBP is the best strategy for resin-matrix ceramic and resin composite repairs.

“…On the other hand, when cementing a LiSi crown with a universal cement such as Panavia SA Cement Universal, no separate silane application is needed, as this cement already contains silane in the form of Long‐carbon chain Silane Coupling Agent (LSCi), that has already proven to be effective in providing a good bond to both ceramics and dentin 19 . If however RelyX Universal (silane‐free cement) is used for the luting of glass–ceramics, priming an indirect restoration with Scotchbond Universal Plus is necessary, since this adhesive system contains a mixture of silanes that showed promising laboratory results 32 . Hence, the available laboratory data suggests that when using a URC, a separate silanization step is not necessary, thus reducing the potential economic cost of obtaining a separate silane coupling agent.…”

ObjectiveWe aimed to introduce the concept of “Selective adhesive luting—SAL” which is explained through clinical steps and supported by preliminary laboratory evidence.Clinical ConsiderationsCementation with rubber dam is difficult to perform in case of short abutment teeth and/or subgingival crown margins. By means of universal resin cements/universal adhesive systems, which can be employed in self‐adhesive as well as adhesive luting procedures, this paper presents a novel technique allowing clinicians to perform reliable cementation where rubber dam isolation is difficult. The SAL technique entails the application of a universal adhesive system only on easily accessible abutment surfaces, enabling simultaneous adhesive and self‐adhesive luting in different portions of the abutment. The SAL clinical workflow is explained through prosthodontic rehabilitation of maxillary right central incisor affected by microdontia and restored with a lithium‐disilicate crown. Furthermore, our laboratory microshear bond strength study supports the rationale behind SAL application demonstrating higher bond strength even when the adhesive resin is placed only on one portion of the cementation substrate.Clinical SignificanceThis article advocates the application of SAL technique in clinical situations where effective adhesive luting is uncertain, since it can improve the adhesion between the tooth and universal resin cements.
