“…In another representative of the group, a proprietary long-chain silane monomer was introduced in the base paste of the cement itself, which does not contain 10-MDP, enabling the preservation of its chemical structure (commercial literature). These modifications possibly underlie the demonstrated improvement of bonding properties to composite, ceramics, and zirconia compared to several competitors (Atalay et al 2022; Rohr et al 2022) when used in conjunction with the recommended UA or a comparable bond strength in self-adhesive mode to a competitor that requires a separate silane application (Yoshihara et al 2020). The performance of URCs is not only material group related but also material specific.…”

“…Similarly, while 1 URC system exhibited improved bond strength to composite blocks (Rohr et al 2022), another demonstrated inferior outcomes when compared to a self-adhesive cement placed after a silane primer (Takahashi et al 2022). Further, it is important to note that the bond strength of URCs to enamel is lower at baseline (Atalay et al 2022) or after artificial aging (Rohr et al 2022) compared to several multistep or self-adhesive resin cements. As these materials are relatively new on the market, laboratory data are scarce, and clinical data are lacking.…”

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.

“…Then, a Teflon jig (2.3 mm inner diameter—3 mm high) was attached to the enamel surface. The composite resin was inserted in two increments, and each increment was polymerized for 20 s. After light curing, the Teflon tube around the composite resin was removed, and the specimens were kept in distilled water at 37°C for 24 h. The SBS test was performed in a universal testing machine (LR50K, Lloyd Instruments Ltd., Fareham, Hants, UK) with a knife‐edge testing apparatus at a crosshead speed of 1 mm/min 35 . Bond strength was expressed in megapascals (MPa) as the ratio of fracture load and bonding area 36…”

Objective: To evaluate the effects of six whitening toothpastes with different whitening ingredients as follows: abrasives, polyphosphates, activated charcoal and hydrogen peroxide on the color, and shear bond strength (SBS) of enamel.Materials and Methods: Thirty-five extracted human molars were sectioned in mesiodistal direction, providing 70 enamel specimens and randomly divided into seven groups having different whitening ingredients (n = 10). After baseline color measurements, the specimens were brushed three times daily for the 30 s. At the end of 2 weeks, spectrophotometric readings were repeated, and color change parameters were calculated. Then, composite cylinders were built on the enamel surfaces and the specimens were subjected to SBS test. Failure modes were determined under a stereomicroscope (Â10). One specimen from each group was examined with scanning electron microscope (SEM). The data were statistically analyzed using Kruskal-Wallis, Wilcoxon signed, one-way-ANOVA (p = 0.05).Results: Clinically acceptable color change was observed in all whitening toothpastes. There were no significant differences among the groups for Δa, ΔL, ΔE 00 , and ΔWI D (p > 0.05). The differences among the groups were not significant regarding SBS and failure mode distributions (p > 0.05). SEM findings were in line with the SBS test and failure mode distribution results.Conclusions: All the tested whitening toothpastes showed similar and clinically acceptable efficacy on the color change of the enamel and led to comparable SBS values.Clinical Significance: The tested whitening toothpastes had an acceptable whitening efficacy and did not have a negative effect on the bond strength to the enamel.

“…This surely impacts their bonding performance to tooth tissues and restorative materials. RXU combined with the pertinent adhesive demonstrated bond strength to dentin and enamel comparable to Panavia V5 (Kuraray Noritake) 48 and G‐Cem One self‐adhesive cement (GC, Tokyo, Japan) 49 placed with the G‐Cem One Adhesive Enhancing Primer (GC), while in enamel, the universal system yielded lower results or at baseline (compared to G‐Cem One, GC), or after thermocycling (compared to Panavia V5, Kuraray Noritake) 48 . Bond strength of RXU comparable or better than several self‐etch and multi‐step cements was also demonstrated in root dentin 50…”

ObjectivesCurrently, a classification of resin cements that includes relatively recently formulated (“universal”) cements is lacking. Furthermore, the terminology used to define different resin cements in the scientific reports is inconsistent. Accordingly, this work aims to: (i) propose a novel classification of resin composite cements; (ii) disambiguate the term “universal cements” and (iii) present an overview of the properties of these cements.MethodsAn analysis of peer‐reviewed literature (PubMed search), as well as market research on definitive resin composite cements were performed.ResultsA tendency toward simplified and versatile luting materials was observed both in the scientific literature and on the dental market with the advent of self‐adhesive/one‐step resin cements. However, additional priming procedures were necessary to improve their bonding performance in certain clinical situations. Hence, several cements that can be applied both in adhesive and self‐adhesive mode were introduced. These cements are associated with a universal adhesive resin, that can be used as a tooth and/or restorative material primer, without the need for other priming systems, regardless of the substrate. These systems should be considered truly universal. Therefore, we hereby suggested a new classification of resin‐based cements: (1) adhesive/multi‐step; (2) self‐adhesive/one‐step; (3) universal cements (one‐ or multi‐step). Despite promising in vitro results, clinical trials and long‐track laboratory studies are necessary to confirm the reliability of the universal cements.ConclusionsThis review presented the current advances in the field of resin‐based cements, which are reflected in the proposed classification. The term “universal cement” was disambiguated, which will help standardize the terminology used in published research.Clinical SignificanceThe classification of resin‐based cements and a better understanding of the proper terminology will help standardize the terminology in published research, as well as improve the understanding of the clinical practitioners of the different indications and possible modalities of use of the available cements.
