Interaction of resin-modified glass-ionomer cements with moist dentine

Journal of Dentistry, 2004
The 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, 1995
Diametral 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.

Effects of aging on repair of resin‐modified glass–ionomer cements

Journal of Oral Rehabilitation, 2000
The effects of aging on the repair bond strengths of resin‐modified glass–ionomer cements after different methods of surface conditioning were studied. Surface conditioning methods included the following: maleic acid; maleic acid with resin application; polyacrylic acid; polyacrylic acid with resin application.

Evolution of Anticariogenic Resin‐Modified Glass Ionomer Cements

ChemBioEng Reviews, 2021
AbstractWith advancing technology and exponential growth in scientific research, new perspectives in dental materials are being discovered. Conservative dentistry advocates maximum tooth preservation by revised restorative materials. Resin‐modified glass ionomer cement (RMGIC) is a flexible group of dental materials that can be used for restoring ...

Resin-modified glass ionomer cements: Bonding to enamel and dentin

Dental Materials, 1996
This 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 ...

Hydrolytic degradation and cracks in resin‐modified glass‐ionomer cements

Journal of Biomedical Materials Research Part B: Applied Biomaterials, 2004
AbstractWater‐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 ...

Water sorption characteristics of resin-modified glass-ionomer cements

Biomaterials, 1997
When restorative materials take up water, their dimensions and structural integrity may be affected. This study determined, using gravimetric measurements, the water sorption characteristics of four resin-modified glass-ionomer cements (RMGICs) immersed in either distilled water or artificial saliva.

Surface pH of resin-modified glass polyalkenoate (ionomer) cements

Journal of Dentistry, 1992
The recently developed group of materials known as light-activated, or resin-modified, glass polyalkenoate (ionomer) cements have been produced in response to clinical demands for a command set cavity base material. This study monitored the surface pH of three commercially available resin-modified glass ionomer cements over a 60-min period following ...

Resin-modified glass ionomer, modified composite or conventional glass ionomer for band cementation?--an in vitro evaluation

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

Adhesion of resin-modified glass ionomer cements using resin bonding systems

Journal of Dentistry, 1998
To compare the in vitro shear bond strength of two commercially available resin-modified glass ionomer cements (RmGIC) to bovine dentine, with and without the use of adhesive bonding systems.Ninety-six flat bovine dentine surfaces were divided into eight groups for bonding procedures. Fuji II LC and Vitremer were bonded to dentine that had been treated
