Summary: Cementation of indirect restorations is a crucial step in dentistry, with the goal of achieving a strong bond between the restoration and the prepared tooth structure. Various dental cements have been developed to meet the requirements of different clinical cases. Glass-ionomer and resin cements are the most commonly used types. Factors such as cement shade, thickness, and surface treatment of both the substrate and restoration contribute to the success of the cementation process.

Summary: The study successfully synthesized and characterized silver nanoparticles (SNP) using a green approach, and incorporated them into commercially available GIC formulation. Results showed that the nanoparticles were positively charged with an average diameter of 122 nm, their addition to GIC had non-significant effects on microhardness and compressive strength, but significant color change and presence of pores were observed.

Summary: This study found that acid-base glass ionomer cements can act as solid-state buffers, adjusting pH value by adding acid or alkali. Different brands and ages of cement have varying effects on the pH of solutions, with statistically significant differences observed.

Summary: The aim of this study was to evaluate the fluoride release, recharge, and cytotoxicity in glass ionomer cements (GICs) reinforced with titanium dioxide nanoparticles (TiO2N). The results showed that the experimental groups had higher and more consistent fluoride release compared to the control groups. The addition of TiO2N enhanced the recharge ability of the GICs. No cytotoxic activity was observed in the experimental groups.

Summary: The study aimed to investigate the volumetric abrasive wear of high-viscosity glass ionomer cement (hvGIC) and a glass hybrid restorative system (ghRS) as potential alternatives to amalgam. Results showed that the wear rates of hvGIC and ghRS were similar and not affected by resinous coating. Both hvGIC and ghRS displayed higher abrasive wear compared to conventional GIC, but fell short of the abrasion resistance of the hybrid composite resin.

Summary: The study found no significant differences in wear rates between high-viscosity glass ionomer cement and glass hybrid restorative system, regardless of resinous coating. Both materials showed significantly higher abrasive wear compared to conventional glass ionomer cement, but fell short of the abrasion resistance values of hybrid composite resin.

Summary: The study found that there was no significant difference in wear rates between hvGIC and ghRS, and the resinous coating did not affect this. Restorations of hvGIC and ghRS showed significantly higher wear resistance compared to CR, while the conventional GIC underperformed.

Summary: The study investigated the volumetric abrasive wear of high-viscosity glass ionomer cement (hvGIC) and a glass hybrid restorative system (ghRS), finding that they did not perform as well as hybrid composite resin (CR) in wear resistance. The resinous coating did not effectively protect against advanced abrasive wear. Under occlusal loading, caution should be taken when using hvGIC or ghRS as alternatives to amalgam or composite resin for posterior teeth restoration.

Summary: hvGIC and ghRS showed similar wear rates, unaffected by resin coating. Both materials exhibited higher wear compared to CR, while conventional GIC had significantly less wear.

Summary: This laboratory investigation aimed to synthesize and characterize micron-sized Gum Arabic (GA) powder and incorporate it in commercially available GIC luting formulation for enhanced physical and mechanical properties of GIC composite. The effect of different weight percentages of GA reinforcement on various properties of GIC materials was evaluated. The results showed that the addition of lower weight ratios of oxidized GA in GIC formulation can enhance the mechanical properties with a slight increase in water solubility and sorption parameters.

Summary: This laboratory experiment aimed to enhance the mechanical properties of glass ionomer cement (GIC) by altering its composition with the addition of micron-sized silanized glass fibers (GFs). The study found that reinforcing GIC with 0.5 wt.% silanized GFs improved its physical and mechanical attributes without affecting other properties.

Summary: In this study, the researchers evaluated the in vivo biocompatibility of conventional ionomer cements modified with Chlorhexidine (CHX) at different time intervals. They found that the cements with addition of CHX demonstrated good biocompatibility with tissues and promoted tissue repair.

Summary: This in vitro study evaluated erosive wear and color change of high-viscosity glass ionomer cements after pH cycling in two erosive media. The acidic media, particularly Aceto balsamico, caused significant erosive wear on all three materials. pH cycling in both acidic media and the control group resulted in significant changes in color values.
