The repair potential of resin-modified glass-ionomer cements

Dental Materials, 2010
To assess the repair potential of resin-modified glass-ionomer cements (RMGICs) with additional RMGIC and resin composite.Specimens of two proprietary RMGICs (Ketac N100 (Ketac Nano), 3M/ESPE, St Paul, MN; Fuji II LC, GC Corporation, Tokyo) were prepared and stored in water at 37 degrees C for 4 days. The surface of the RMGIC was finished flat with 600-

Wear of resin-modified glass ionomers : an in vitro study

Journal of Clinical Pediatric Dentistry, 2001
The purpose of this study was to evaluate the wear resistance and clinical applicability of resin-modified glass ionomer cements as restorative or fissure-sealing materials. The in vitro wear of resin-modified glass ionomers was compared to conventional glass ionomers, a resin-based sealant, and a composite resin. A three-body wear test (enamel block -

Physical property investigation of contemporary glass ionomer and resin-modified glass ionomer restorative materials

Clinical Oral Investigations, 2018
The objective of this study was to investigate selected physical properties of nine contemporary and recently marketed glass ionomer cement (GIC) and four resin-modified glass ionomer cement (RMGI) dental restorative materials.Specimens (n = 12) were fabricated for fracture toughness and flexure strength using standardized, stainless steel molds ...

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.

[Resin-modified glass-ionomers in dentistry].

Nederlands tijdschrift voor tandheelkunde, 2002
The resin-modified glass-ionomers contain the essential components of both a conventional glass-ionomer and a visible light-cured resin. They have several advantages like longer working time, shorter setting time, bonding to tooth structure, fluoride-release, better aesthetics than conventional glass-ionomers and ease in use.

Development of a Self-etch Adhesive for Resin-modified Glass Ionomers

Journal of Dental Research, 2006
The favorable self-adhesiveness of resin-modified glass ionomers (RMGIs) might be even further improved if the time-consuming and technically sensitive etch-and-rinse pre-treatment step with polyalkenoic acids could be avoided. We undertook this study to assess the effectiveness of an experimental self-etch adhesive for RMGIs that does not need to be ...

Failure of resin-modified glass-ionomers subjected to shear loading

Journal of Dentistry, 1999
The mechanism of bond failure of resin-modified glass-ionomers is unknown. This study examined the failure on shear loading at the dentine interface of these materials. Twenty-five teeth (embedded in acrylic blocks) were sectioned longitudinally to expose a flat dentine surface.

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).

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 ...

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.
