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

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).

Fracture toughness of resin-modified glass ionomers.
American journal of dentistry, 1996To measure and compare the fracture toughness of a multi-purpose resin composite, four light-cured glass ionomers, one light-cured resin ionomer, and two silver-containing glass ionomers.Ten specimens were fabricated for each of the eight materials: Herculite XRV, Fuji II LC, Photac-Fil, Vitrebond, Photac-Bond, VariGlass VLC, Ketac-Silver, and Miracle ...

Resin-modified glass-ionomer cements.
The International journal of prosthodontics, 1991The recently developed dual-setting resin glass-ionomer cements are discussed, and the question of whether they are the true glass-ionomer cements is addressed. Their chemistry and properties are examined and compared with conventional glass-ionomer cements.

Pulp reaction to a tri-cure resin-modified glass ionomer
Oral Surgery, Oral Medicine, Oral Pathology, Oral Radiology, and Endodontology, 1998This study evaluated the pulp response to a tri-cure resin-modified glass ionomer cement and compared this response to those elicited by a zinc oxide-eugenol cement and a silicate cement. Materials were placed in nonexposed class V cavity preparations on human teeth.Sixty premolars were selected in orthodontic patients in a voluntary group of teenagers.

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.

Crown retention with three resin-modified glass ionomer luting agents
The Journal of the American Dental Association, 2012The author used a standardized technique to investigate the retentive properties of three resin-modified glass ionomer (RMGI) cements in the cementation of precious gold copings.The author machined premolars on a jeweler's lathe to a taper of 16 ± 0.5 degrees. The occlusal table measured 4 millimeters.

Solubility of a resin-modified glass ionomer cement.
ASDC journal of dentistry for children, 1998Thirty standardized discs were fabricated from a resin-modified glass ionomer cement (Vitremer -3M) using three different powder/liquid ratios. All specimens were immediately weighed. Specimens were stored in artificial saliva for thirty days. Twice each day the specimens received a 30-min.

Resin-modified glass-ionomer materials. Part 1: Properties.
Dental update, 1996The resin-modified (light-cured) glassionomer cements were developed as hybrids of the conventional glass-ionomer materials to overcome some of their disadvantages. These new materials will be reviewed in two parts. This first article deals with their physical and biological properties. Part 2 will cover their clinical applications and handling.
