“…Therefore, HEMA was replaced with UDMA to reduce the aforementioned drawbacks. UDMA has been frequently used as a bonding agent due to better flexibility, low solubility, low water-absorbing characteristics, and its ability to inhibit transesterification [ 55 ]. The comparative spectra of the experimental adhesives confirmed the presence of urethane with stretching and bending peaks of N-H at 3310 cm −1 and 1542 cm −1 , respectively.…”

This study aimed to evaluate the incorporation of zirconia/silver phosphate nanoparticles to develop experimental dental adhesives and to measure their physical and mechanical properties. The nanoparticles were synthesized by the sonication method, and the phase purity, morphological pattern, and antibacterial properties with Staphylococcus aureus and Pseudomonas aeruginosa were assessed. The silanized nanoparticles were incorporated (0, 0.15, 0.25, and 0.5 wt.%) into the photoactivated dimethacrylate resins. The degree of conversion (DC) was assessed, followed by the micro-hardness and flexural strength/modulus test. Long-term color stability was investigated. The bond strength with the dentin surface was conducted on days 1 and 30. The transmission electron microscopy and X-ray diffractogram confirmed the nano-structure and phase purity of the particles. The nanoparticles showed antibacterial activities against both strains and inhibited biofilm formation. The DC range of the experimental groups was 55–66%. The micro-hardness and flexural strength increased with the concentration of nanoparticles in the resin. The 0.5 wt.% group showed significantly high micro-hardness values, whereas a non-significant difference was observed between the experimental groups for flexural strength. The bond strength was higher on day 1 than on day 30, and a significant difference was observed between the two periods. At day 30, the 0.5 wt.% showed significantly higher values compared to other groups. Long-term color stability was observed for all the samples. The experimental adhesives showed promising results and potential to be used for clinical applications. However, further investigations such as antibacterial, penetration depth, and cytocompatibility are required.

“…The hybrid layer serves to combine 2 different elements, namely hydrophilic dentin, and hydrophobic composite material, protecting the dentin surface from microleakage and increasing dentin resistance to acid. The ideal hybrid layer is characterized by the presence of a collagen network that is bonded and reinforced with polymers (3,15).…”

“…EGCG as a cross-linking agent and the wetting ability of the bonding material caused by the EGCG solvent, which is water. The use of different solvents can also cause differences in test results, Chemical bonding using acetone solvent can produce a stronger bond between the bonding material and dentin collagen when compared to using ethanol solvent (15). A study conducted by Soetojo (32), compared HEMA water solvent expresses less MDA and has good biocompatibility when compared to HEMA with ethanol or acetone solvent.…”

Adhesive dentistry’s main assumption is to create a strong chemical bond between dental hard tissues and restorative composite material. One of the most important aspects of this interface is the hybrid layer. Unfortunately, due to physical and chemical causes, the hybrid layer wears away with time. Epigallocatechin-3-gallate (EGCG), a component extracted from green tea, has several roles in the medical and dentistry field including as a crosslinking agent and as a chelating agent. Although there are several negative results, EGCG was proven to be able to preserve resin-dentin bonds without harming the restoration. As a crosslinking agent and chelating agent, EGCG has the potential to enhance the physical properties of dentin collagen and resin-dentin adhesion. The purpose of this study was to see how EGCG, as a cross-linking agent, affected dentinal collagen and hybrid layers, as well as how chelating chemicals affected Matrix metalloproteinase (MMPs).
