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 ionomers for luting posterior ceramic restorations
Dental Materials, 1995Until recently, esthetic inlay restorations in posterior teeth have been limited to cavities surrounded by enamel. Dentin adhesive systems in combination with luting composites and light-cured resin-modified glass ionomer cements offer a possibility for bonding ceramic inlays to cavities when the cervical margin is in dentin. This study was designed to

In vivo changes in roughness of resin-modified glass ionomer materials
Dental Materials, 1997The clinical changes in roughness of resin-modified glass ionomer materials is relatively unknown. This study examined the in vivo wear of these materials using surface roughness as an indicator of wear patterns.Ten patients with four cervical abrasion lesions each were selected. The four cavities in each patient were restored with Fuji II LC (GC Corp.,

Effects of aging on repair of resin‐modified glass–ionomer cements
Journal of Oral Rehabilitation, 2000The 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.

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.

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 ...

Surface finishing of resin-modified glass ionomer.
General dentistry, 2004This study utilized spectrophotometry to evaluate in vitro superficial dye deposition on resin-modified glass ionomer, following different surface finishing and polishing treatments. Materials that were photocured adjacent to the mylar strip produced the surfaces with the lowest mean after superficial staining.

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.

Failure of resin-modified glass-ionomers subjected to shear loading
Journal of Dentistry, 1999The 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.

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.
