“…Plus, incomplete evaporation of the water and ethanol solvents in OBFL can significantly reduce the bond strength. This can explain why A and AAA resulted in superior bond strength values compared to the other techniques due to sufficient solvent removal [34]. In addition, this is due to the inclusion of filler in the composition of OBFL and the close attention to the application technique [3,35].…”

The goal of this article was to assess the effect of modified triple-layer application (MTLA) in conjunction with the active bonding technique on the bond strength of four adhesive systems to dentinal substrate. The adhesives tested were Prime&Bond Universal (PBU), OptiBond Universal (OBU), OptiBond FL (OBFL), and Clearfil SE (CSE). The adhesives were applied according to the following strategies: single active application (A) and triple adhesive layer application including Active–Passive–Passive (APP); AAP; and AAA. The micro-tensile bond strength test was evaluated following 24 h or 6 months of storage. The composite–dentin interface morphology was investigated using scanning electron microscopy. The data were statistically analyzed with a significance level of α = 0.05. At 24 h of aging, all of the factors tested were not significant (p > 0.05) for CSE. For OBFL, OBU, and PBU, statistically higher values were observed for the A technique (p < 0.05). Plus, there were no significant variances between the APP, AAP, and AAA techniques (p > 0.05) for OBFL and PBU. However, for OBU, there were no significant differences between the A and AAA techniques (p > 0.05). After 6 months of aging, the A technique showed statistically higher values when compared to the other techniques (p < 0.01), except for OBFL, where the A and AAA techniques showed promising outcomes. When comparing the bond strength values of 24 h and 6 months, only for PBU, all of the techniques used resulted in bond strength stability over time (p > 0.05). Thicker adhesive layers were observed when MTLA was applied. Only the OBFL adhesive showed the formation of resin tags in all of the modalities tested. The bonding performances of the different application techniques used were material-dependent.

“…Зменшення кількості етапів адгезивного протоколу за рахунок використання АС VII генерації знижує ризики постопераційної чутливості зубів, скорочує час лікування, але міцність адгезивного з'єднання є нижчою в порівнянні з АС V покоління, які завдяки своїм фізико-механічним властивостям залишаються найбільш популярними на щоденному стоматологічному прийомі [3]. Ефективність АС V генерації, в свою чергу, більше залежить від прецизійного виконання етапів адгезивної підготовки, відповідно до інструкцій фірм-виробників, що підвищує ризики розвитку негативних наслідків для пульпи зубів [7].…”

“…З огляду на сучасні наукові знання, однією з основних проблем відновлення анатомічної форми зубів прямими реставраціями постає створення довговічного та надійного зв'язку між композитом і дентином зубів [6,7,8]. Подальше вдосконалення АС спрямоване на забезпечення високої інтеграції їх мономерів до структур твердих тканин зубів, спрощення техніки роботи з ними, підвищення фізикомеханічних властивостей та зменшення шкідливого впливу на пульпу зубів.…”

“…It shortens the treatment time, but the strength of the adhesive connection is lower compared to ASs V generation, which, due to their physical and mechanical properties, remain the most popular in daily dental practice [3]. The effectiveness of AS V generation, in turn, depends more on the precise execution of the stages of adhesive preparation following the instructions of the manufacturing companies, which increases the risks of developing negative consequences for the dental pulp [7].…”

“…In view of modern scientific knowledge, one of the main problems of restoring the anatomical shape of teeth with direct restorations is creating a durable and reliable connection between the composite and the dentin of the teeth [6,7,8]. Further improvement of AS aims to ensure high integration of their monomers into the structures of hard dental tissues, simplifying the technique of working with them, improving physical and mechanical properties and reducing the harmful effect on dental pulp.…”

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.

This preregistered ex vivo investigation examined the dentinal hybrid layer formation of a resinous infiltrant (Icon), with reference to both thickness (HLT) and homogeneity when combined with modified tunnel preparation (occlusal cavity only) and internal/external caries infiltration. The adhesives Syntac and Scotchbond MP were used as controls (Groups 1 and 3) or in combination with Icon (Groups 2 and 4). A split-tooth design using healthy third molars from 20 donors resulted in 20 prepared dentine cavities per experimental group. The cavity surfaces (n = 80) were etched (37% H3PO4), rinsed, and air-dried. Rewetting with ethanol was followed by application of the respective primers. After labeling with fluorescent dyes, either Syntac Adhesive/Heliobond or Scotchbond MP Adhesive was used alone or supplemented with Icon. HLT, as evaluated by scanning electron microscopy, did not significantly differ (P > 0.05), and confocal laser scanning microscopy revealed homogeneously mixed/polymerized resin-dentine interdiffusion zones in all groups. Icon can be successfully integrated into an ethanol-wet dentine bonding strategy, and will result in compact and homogeneous hybrid layers of comparable thickness considered equivalent to the non-Icon controls, thus allowing for preservation of the tooth’s marginal ridge and interdental space in the case of internal/external infiltration of proximal caries.
