The kinetics of ion release by glass-ionomer cements
… one in-house conventional GIC made from G338 glass powder, one commercial glass-ionomer bone cement and four in-house novel aluminium free Fe2O3 based GICs. Cylindrical specimens of GICs were prepared in stainless steel moulds to form 6 mm height x 4 mm diameter cylinders which were then …

Evaluation of Shear Bond Strength of Two Resin-Modified Glass-Ionomer Cements
… a new paste-paste formulation of resin-modified glass-ionomer cement (Rm-GIC) to an exising powder-liquid formulation. The study will test the hypothesis that the new paste-paste formulation of Rm-GIC (Fuji-Cem ™, GC Corp, Tokyo, Japan) has the same bond strength as an existing popular …

Evaluation of Tensile Bond Strength of Glass Ionomer Cements for Orthodontic Bonding
Glass ionomer cements offer advantages over conventional composite resins when used for orthodontic bonding. These include chemical bonding to enamel, fluoride release, and ease of removal from enamel upon debonding. This study evaluated the tensile bond strengths of three Type I (luting) and three …

ULTRASONIC ROOT-END PREPARATION AND SEALING ABILITY OF CONVENTIONALLY-SETTING GLASS IONOMER CEMENTS IN SURGICAL ENDODONTICS
… (CFP) was performed. The conventionally-setting glass ionomer (GIC) Fuji IX showed least leakage. CFP demonstrated through pores in all teeth, whereas FTM did not. CFP appeared to be a useful method for leakage evaluation. In chapter 3 and 4 the long term sealing ability of root-end filling …

Microleakage in new resin-modified glass ionomer cements using new no-rinse conditioners : an in-vitro study
Since their introduction in 1970, glass ionomer cements have been used in a wide variety of clinical situations in dentistry. The main advantages of glass ionomer cements are chemical bonding, fluoride release and uptake, excellent seal against microleakage, and biocompatibility. The main objective …

The Comparison of the Tensile, Shear-Peel, and Torque Orthodontic Bond Strength Test Methods Performed on a Resin and Two Glass Ionomer Cements
… (R), light-cured (LC), and chemically cured (CC) glass ionomer. Sixty-three bovine incisors were randomly divided into three groups. Stainless steel incisor brackets were bonded to the prepared facial surfaces, and the specimens were stored in deionized water at 37° C for 38 hours. The specimens …

Clinical Evaluation of Glass Ionomer Cement as an Adhesive for the Bonding of Orthodontic Brackets
Glass ionomer cement has been shown in previous studies to retard decalcification and caries formation. This cement would be valuable in orthodontics if it proved to have adequate adhesive properties. Therefore, this study was designed to determine if there is a significant difference in the …

Fundamental studies on ionomer glasses
… relationships were studied in glasses of the type used to produce glass lonomer dental cements. These materials are currently being developed as a bone cement in joint replacement surgery. Initially, a simple quaternary (25i02-Al203-CaO-CaF2) glass was produced and was found to …

Effect of zinc substitution on the structure of calcium Fluoro-Alumino-Silicate glasses and glass-ceramics
Ionomer glasses are certain glass compositions that have been used as the glass component in glass ionomer cements. The term “ionomer” was traditionally related with the use of polyacrylic acid as the polymeric component of glass ionomer cements that incorrectly was characterized as an ionomer …

The mechanical and other properties of ionomer cements
Ionomer cements, a novel composite material, are formed at ambient temperatures by mixing an aqueous polyacid with an ion-leachable powder. The glass ionomer cement known as ASPA, a dental restorative material, produces strong and hydrolytically stable cements. Applications of this material outside …

Evaluation of the Tensile Bond Strength of Orthodontic Bracket Bases Using Glass Ionomer Cement as an Adhesive
… oral environment has led to experimentation with glass ionomer cements. This study compared the tensile bond strength of eight different orthodontic bracket base designs in vitro and assessed the amount of adhesive remaining on the bracket pad after debonding. Each bracket base design included in …

Release of antimicrobial compounds from glass-ionomer dental cements
… a study of the possibility of using conventional glass-ionomer cements (GICs) as matrices for release of antimicrobial compounds. Sodium fusidate, cetyl pyridinium chloride (CPC), benzalkonium chloride (BACH), triclosan and triclosan/zinc citrate at concentrations ranging from 1% to 5% by weight …
