“…In addition, its physical and chemical properties allow resin-based restoration to endure daily oral challenges and preserve its integrity, lust, and color stability over the years [2]. However, there is no single ideal material for all clinical situations; therefore, it is necessary to know the characteristics and behaviors of each material for a better indication [3,4].…”

Objectives: Resin composites containing surface pre-reacted glass (S-PRG) were introduced to reduce demineralization and improve remineralization of the tooth structure. However, water diffusion within the material is necessary for its action, which can impair its overall physical-mechanical properties over time, including the color stability. This study aimed to evaluate the color stability and related degree of conversion (DC) of four resin composites.Materials and Methods: Discs (n=5/group) of microhybrid, nanofilled, nanohybrid, and S-PRG-based nanohybrid composites with two opacities were prepared. Color (CIELab and CIEDE2000) was evaluated after aging in grape juice. The DC was analyzed by using Fourier Transform Infrared Spectroscopy before and after photopolymerization. Data were statistically analyzed by using two-way analysis of variance and post-hoc least significant difference tests (P<.05).Results: In the color stabilityanalysis, the interaction between filler type and opacity was significant. S-PRG influenced color stability and DC.Conclusions: The nanohybrid resin composite presented favorable color stability and a greater DC, which is likely related to its organic content. S-PRG based nanohybrid resins require caution since its bioactive benefits depends on interaction with the environment that can be prone to impair color stability.Clinical Relevance: As color stability is mandatoryin specific regions, staining can jeopardize the esthetics of a resin composite. The use of nanohybrid composites with no or reduced BisGMA content and diluents may be more appropriate in these areas. Since materials containing S-PRG can offer relevant benefits, professionals need to balance their higher susceptibility to staining favoring other relevant properties.

“…In particular, after the introduction of MWCNTs into the silane coating, CNT/SL-CF exhibited further improvements of approximately 12% and 8% before and after immersion, respectively. Studies have also been conducted on the introduction of amino and epoxy groups on the surface of CFs and silica to graft nano-silica onto CFs, 59,60 as well as on the use of 3-aminopropyltriethoxysilane (APS) 61 and crystalline poly(ether ketone) (PEEK) 62 to modify the surface of the fibers to improve the interfacial strength of the composites. Another scholar 63 treated the surface of jute fibers with alkali and silane; the change in the flexural strength of the composites with immersion time before and after modification is shown in Figure 8(f).…”

Fiber-reinforced polymer (FRP) composites are widely used in marine engineering fields, such as coastal construction, offshore bridges, submarines, and warships, owing to their light weight, high strength, and corrosion resistance. However, owing to the harsh marine environment, FRP composites used in the ocean are inevitably affected by seawater aging. Therefore, it is necessary to investigate the seawater aging properties of FRP composites. In this study, the seawater aging mechanism of FRP composites is summarized, and the influence factors (matrix type, fiber type, immersion temperature, loading mode, and aging method) of seawater aging on the mechanical properties of FRP composites are further reviewed in detail. Based on this, the method for improving the seawater resistance of FRP composites is summarized. In addition, the research schemes of accelerated aging of FRP composites and commonly used life prediction models are summarized, and the methods and suggestions for improving the accuracy of life prediction are further discussed.

“…Despite many apparent advantages, GIC is not recommended for restoration in stress bearing areas as it was observed to have lower mechanical properties, fracture toughness, and wear resistance than composite resins . Many materials have been incorporated into the powder and liquid to compensate for poor mechanical properties such as nanoparticles, fibers, silica, and hydroxyapatite. − Resin-modified glass ionomer cement (RMGIC) was introduced in 1988 to overcome some of the shortcomings of GIC. Due to the inclusion of a resin monomer, their properties fall somewhere between the properties of composites and GIC .…”

This study aims to synthesize and characterize lignin-decorated zinc oxide nanoparticles before incorporating them into resin-modified glass ionomer cement (RMGIC) to improve their anticariogenic potential and mechanical properties (shear bond strength and microhardness). Probe sonication was used to synthesize lignin-decorated zinc oxide nanoparticles which were then characterized via scanning electron microscopy, Fourier transform infrared spectroscopy, and X-ray diffraction. Following characterization, these were incorporated in RMGIC (Gold label, Fuji II LC). Three major groups, experimental group A (EGA), experimental group B (EGB), and control group (CG), were outlined. EGA and EGB were divided into numbered subgroups based on the ascending concentrations of nanoparticles (5, 10, and 15%) of lignin-coated zinc oxide and zinc-oxide, respectively. CG served as a control and comprised cured RMGIC samples without any incorporation. Anticariogenic analysis was conducted on experimental RMGIC samples via disk-diffusion (n = 3) and direct contact test (n = 3) against Streptococcus mutans (ATCC 25175). Optical density values for days 1, 3, and 5 were recorded via a UV− Vis spectrophotometer. A shear bond strength test was performed using 35 premolars. The adhesive remnant index was used to estimate the site of bond failure. For the Vickers microhardness test (n = 3), 100 g of load at 10 s dwell time was set. Atomic absorption spectroscopy was performed over 28 days to determine the release of zinc from the samples. All tests were analyzed statistically. The anticariogenic potential of EGA and EGB was significantly greater (p ≤ 0.05) than that of the control. The shear bond strength test reported the highest value for EGA15 with all groups exhibiting failure at the bracket/RMGIC interface. The microhardness of EGA15 yielded the highest value (p ≤ 0.05). Release kinetics displayed a steady release with EGB15 exhibiting the highest value. The EGA and EGB samples displayed good anticariogenic potential, which was sustained for 28 days without any deleterious effect on the shear bond strength and microhardness.
