“…Also, the composition of monomers in universal AS significantly impacts the strength of adhesion to dentin. The average values of the adhesive bond strength of AS containing 10-methacryloyloxyethyl dihydrogen phosphate and 4-methacryloyloxyethyl trimellitate anhydride in laboratory conditions were more than two times higher, namely 17.55+9.47 MPa, relative to the values of AS with traditional monomers -7.88+8.83 MPa [25].…”

“…Також значний вплив на міцність адгезії до дентину відіграє склад мономерів в універсальній АС. Середні значення сили адгезивного зв'язку АС, що містять 10-метакрилоїлоксіетилдигідрофосфат та 4-метакрилоїлоксіетил тримелітату ангідрид у лабораторних умовах були більш ніж в 2 рази вищими, а саме 17,55+9,47 МПа, відносно показників АС з традиційними мономерами -7,88+8,83 МПа [25].…”

The widespread use of adhesive systems in many branches of modern dentistry is often accompanied by complications associated with their physical, mechanical and biological characteristics, mistakes at the stages of adhesive preparation, and the irrational choice of bonding agents for individual clinical situations. The work aimed to study the known physical, mechanical and clinical properties of modern adhesive systems, the latest trends and approaches to their improvement, and prospects for the further development of restorative dentistry. The most popular adhesive systems for direct photocomposite restorations remain bonds of the V and VII generations, which are used according to the classic protocols of total etching or self-etching, respectively. The obtained results of laboratory and clinical studies of these adhesive systems are often contradictory and emphasize the problem of creating a reliable connection between the photocomposite and the dentin of the teeth. In order to increase the clinical effectiveness of direct photocomposite restorations, universal adhesive systems and self-adhesive composites were developed, which have extended indications for use in certain clinical situations and significantly simplify adhesive preparation. However, the existing experience of using these new materials also demonstrates the development of complications, even in the short period of operation of restorations. To date, no adhesive systems have an optimal set of physicomechanical and clinical characteristics for the direct restoration of defects in the hard tissues of teeth with photocomposite materials. The known results of laboratory and clinical studies of similar adhesive systems demonstrate significant discrepancies regarding the indicators of adhesive strength, the tightness of the dentin-photocomposite interface, the success of restorations, which is explained by the lack of standardized methods of their testing and clear criteria for evaluating clinical effectiveness.

Context: The significance of enamel etching has been well-researched and established. Limited literature is available comparing the enamel bond strengths of the two-step self-etch adhesive system and the newly introduced universal adhesive (UA) system with prior acid etching. Aims: The aim of the study was to evaluate and compare the microtensile bond strength (μTBS) of composite to enamel with and without 37% orthophosphoric acid pre-etching using a recently introduced UA and a two-step self-etch adhesive. Subjects and Methods: This in vitro , experimental study was conducted on 48 extracted human third molar teeth. Two enamel surface fragments were obtained per tooth, polished using 600-grit silicon carbide abrasive paper, and randomly divided into four groups-CLEARFIL SE BOND with and without acid pre-etching and G-Premio Bond with and without acid pre-etching. The samples were etched using 37% phosphoric acid gel for 30 s, followed by the bonding protocol. Composite resin blocks were built incrementally to a thickness of approximately 6 mm, and the restored samples were stored in distilled water for 24 h at 37°C. They were then sectioned, mounted, and subjected to a μTBS test using a universal testing machine. Statistical Analysis Used: Statistical analysis of the data was performed using one-way ANOVA and Tukey’s post hoc test using SPSS software version 22.0. Results: Samples bonded with the UA subjected to prior acid etching protocol demonstrated the highest enamel μTBS. In contrast, those treated with the two-step self-etch adhesive without prior acid etching demonstrated the lowest enamel μTBS. Pre-etching with phosphoric acid significantly increased the enamel bond strength of both bonding agents, with the universal agent showing better results than the two-step adhesive system. Conclusions: Enamel etching with phosphoric acid significantly increases the bond strength of self-etch adhesives. UA with prior acid etching showed the maximum enamel μTBS. Two-step self-etch adhesive without prior acid etching yielded enamel μTBSs unacceptable for long-term, durable bonding.
