Article Abstract
Aim: This study aims to investigate the adhesive performance of three different universal adhesives to repair aged composite restorations, with or without the application of silane.
Materials And Methods: A hundred and twenty resin composite samples were prepared, aged and randomly divided into 6 main Groups (single bond universal [SBU], All-Bond Universal [ABU], Futurabond U, Clearfil Tri-S Bond, Single Bond 2, and Clearfil SE Bond) and 2 subgroups (with or without silane). A microhybrid composite resin was placed on the aged composite surfaces and light cured. After a micro-shear bonding test, the fracture surfaces were examined under the scanning electron microscopy. Statistical analysis was performed using two-way ANOVA and Tukey's tests.
Results: Among all the universal adhesives, SBU showed the highest bond strength values compared to the other two universal adhesives when used with and without silane ( > 0.05). Between ABU and Futurabond U, no significant difference was observed with silane ( > 0.05) and without silane ( > 0.05). Among conventional adhesives, there was no statistically significant difference ( > 0.05) both with and without silane.
Conclusion: Within the limitations of this study, while SBU can be safely used with and without the application of silane, Futurabond U cannot be used without silane.

Surface properties of direct restorations and adjacent dental tissues after saliva exposure.

This study assessed the effect of saliva exposure on roughness (Ra) and Vickers hardness (VHN) of two direct restorative materials, enamel, and dentin adjacent to the restorations. Enamel and dentin cavities in molars (n = 10) were restored with a) bulk-fill resin composite (Tetric N-Flow Bulk Fill, BF) with the application of a universal adhesive (Tetric N-Bond Universal) and b) alkasite restorative material (Cention N, CN) with and without the application of a universal adhesive. After 24 h (baseline), surface roughness and hardness of the restorative material and dental tissues were assessed at 100 μm from the tooth/restoration interface.

Introduction: This study investigated the effect of sandblasting time and primer type on the shear bond strength of composite attachments to full-contour zirconia crowns.
Methods: A total of 108 zirconia specimens were fabricated and divided into 9 groups (n = 12) according to sandblasting time (10, 30, and 60 seconds) and primer type (silane, 10-methacryloyloxydecyl dihydrogen phosphate [MDP], universal). After sandblasting with 110-μm alumina particles, specimens were primed, and attachments were bonded using a packable composite.
Phase Crosslinking Strategy to Construct Impact-Resistant and Buffer-Enhanced Bilayer Hydrogels with High Interfacial Adhesion.

Inspired by the rigid exoskeleton and elastic inner tissues of crustaceans, a bilayer gel integrating high-strength rigidity and soft cushioning with high interfacial adhesion (1060 ± 40 J m ) is developed via a stepwise solid-liquid phase crosslinking strategy. Herein, a prefrozen high-concentration polyvinyl alcohol (PVA) solution forms a solid-state structural framework, while a subsequently cast low-concentration PVA solution generates a flexible layer. Partial thawing of the frozen gel during casting triggers molecular chain interpenetration at the interface, synergistically enhanced by controlled molecular penetration, freeze-thaw cycles, and salt-induced crystallization.

When cells in a primary tumor work together to invade into nearby tissue, this can lead to cell dissociations-cancer cells breaking off from the invading front-leading to metastasis. What controls the dissociation of cells and whether they break off singly or in small groups? Can this be determined by cell-cell adhesion or chemotactic cues given to cells? We develop a physical model for this question, based on experiments that mimic aspects of cancer cell invasion using microfluidic devices with microchannels of different widths. Experimentally, most dissociation events ("ruptures") involve single cells breaking off, but we observe some ruptures of large groups (~20 cells) in wider channels.

This study aimed to determine the influence of air abrasion on the shear bond strength (SBS) of universal adhesives when using different abrasive powders. The AquaCare Twin served as the injection device. The prepared bovine dentin specimens were air- abraded with alumina particles or bioactive glass before applying the universal adhesive (All Bond Universal, Clearfil Universal Bond Quick ER, or Scotchbond Universal Plus Adhesive).
