Reinforcement of resin-modified glass-ionomer cement with glass fiber and graphene oxide
Journal of the Mechanical Behavior of Biomedical Materials, 2023To evaluate the effect of adding glass fiber and graphene oxide to a resin-modified glass ionomer cement (RMGIC).Experimental RMGICs were prepared by adding separately and simultaneously glass fibers (5, 10, and 20 wt%) and graphene oxide (1, 3, and 5 wt%) to the powder of RMGIC with different ratios. The samples were examined under SEM and XRD.

Interaction of resin-modified glass-ionomer cements with moist dentine
Journal of Dentistry, 2004The objective of this study was to report on a novel phenomenon that occurs when resin-modified glass-ionomer cements (RMGICs) are bonded to moist human dentine.Dentine surfaces from extracted third molars were abraded with 180-grit SiC paper. Ten teeth were prepared for each of the two RMGICs tested (Fuji II LC, GC Corp. and Photac-Fil Quick, 3M ESPE).

Strength and setting behavior of resin-modified glass ionomer cements
Acta Odontologica Scandinavica, 1995Diametral tensile strength (DTS), fracture strength, and Vickers microhardness were tested in three resin-modified glass ionomer cements (GICs), one chemically set GIC, and one dental composite. For the DTS studies test discs were immersed in deionized water at 37 degrees C for 10 min, 1 day, and 28 days, respectively.

The biocompatibility of resin-modified glass-ionomer cements for dentistry
Dental Materials, 2008The biological effects of resin-modified glass-ionomer cements as used in clinical dentistry are described, and the literature reviewed on this topic.Information on resin-modified glass-ionomers and on 2-hydroxyethyl methacrylate (HEMA), the most damaging substance released by these materials, has been collected from over 50 published papers.

Long-term flexural strengths of resin-modified glass-ionomer cements
Biomaterials, 1998The use of resin-modified glass-ionomer cements (RMGICs) in restorative dentistry has expanded since their introduction about seven years ago. These materials have been shown to possess superior initial mechanical properties to those of the conventional glass-ionomer cements.

Resin-modified glass ionomer cements: Fluoride release and uptake
Acta Odontologica Scandinavica, 1995The aim was to study the short- and long-term fluoride release from resin-modified glass ionomer cements (GIC). The aim was also to determine the effect of fluoride treatment of 9-month-old specimens, consistency of the mix, and pH of the environment on the fluoride release. GIC test specimens were continually exposed to running water, and the fluoride

Hydrolytic degradation and cracks in resin‐modified glass‐ionomer cements
Journal of Biomedical Materials Research Part B: Applied Biomaterials, 2004AbstractWater‐absorption affects the basic properties of resin‐modified glass‐ionomer cements (RMGICs). Fick's law is usually invoked to explain the absorption process. The purpose of this study is to show that the absorption in accordance with the Fickian model cannot be extended to the whole of the specimen, and that microcrack formation is the main ...

Resin-modified glass ionomer cements: Bonding to enamel and dentin
Dental Materials, 1996This study was designed to investigate the effect of storage in water on bonding efficacy to enamel and dentin of four resin-modified (Dyract, De Trey Dentsply; Fuji II LC, GC Dental Corp.; Photac Fil, ESPE; Vitremer, 3M Dental Products), one conventional glass ionomer filling material (Ketac Fil, ESPE) and a resin composite system (Pekafill/Gluma ...

Biomaterials, 1998
The fluoride release of conventional and resin-modified glass-ionomers is reviewed and compared to that of fluoride-releasing (polyacid-modified) composite resins. Each formulation displays a typical fluoride release profile. The cumulative amount of fluoride released is described by [F]c = [F](I)t/(t + t1/2) + beta square root t for glass ionomers ...

The European Journal of Orthodontics, 2003
The aims of this study were to compare the mean shear-peel bond strength and predominant site of bond failure of micro-etched orthodontic bands cemented with resin-modified glass ionomer cement (RMGIC; Fuji Ortho LC or 3M Multi-Cure), a modified composite or a conventional GIC. The survival time of bands was also assessed following simulated mechanical
