Summary: This study evaluated the effectiveness of different cleaning strategies to remove sealer residues and the effect of these residues on the bond strength of universal adhesives to dentin impregnated with epoxy resin-based sealer. The results showed that amyl acetate and xylol were effective in removing residues from the sealer, and the cleaning protocols did not affect the bond strength of the universal adhesives.

Summary: This study evaluated the effects of different laser settings and dentin bonding agents on the ultrastructure of dentin interfaces and dentin bond strength. The results showed that laser irradiation altered the bonding mechanism of the adhesives to dentin, reducing the bond strength of self-etching adhesives. The etch-and-rinse adhesive exhibited the highest bond strength at 1 year.

Summary: The study revealed that eugenol-containing and eugenol-free temporary cements exhibit higher residue persistence at the apical region, resulting in reduced bond strength of the dental posts. However, the impact on dentinal penetration is mainly observed in the apical region.

Summary: The study found that the self-adhering flowable resin composite had a lower shear bond strength to dentin compared to the conventional adhesive system composite, indicating poorer bonding to dentin. Furthermore, the self-adhering flowable resin composite predominantly exhibited non-cohesive failure, while the conventional adhesive system composite showed strong adhesive bonding with mixed failure patterns.

Summary: The study evaluated the effect of propolis associated with Biosilicate on bond strength and gelatinolytic activity. The results showed that propolis and the combination of treatments promoted the highest bond strength and preserved dentin. All experimental groups exhibited low gelatinolytic activity, indicating potential for improving composite restoration longevity.

Summary: Dopamine was introduced into a hydrogen bonding-based elastomer to create a material with both mechanical strength and adhesion strength. This elastomer showed high stress and fracture strain, along with high adhesive and underwater adhesive strength, making it suitable for a stretchable bio-interfacial electrode with self-healing properties.

Summary: The study demonstrates a spontaneous redox polymerization process at the adhesive-composite interface to improve bonding prior to composite photocure. By providing time for passive interfacial diffusion of benzoyl peroxide into the aromatic amine-containing composite, redox-initiated interfacial polymerization can occur, leading to a significant increase in micro-tensile bond strength between the adhesive and composite.

Summary: This study evaluated the cleaning potential of ethanol, acetone, and amyl acetate solutions and their effects on the microstructure of epoxy resin-based sealer residues on dentin. The combination of amyl acetate, acetone, and ethanol was found to be the most effective and safe protocol for removing these residues, with minimal reduction in dentin microhardness.
