Statement of Problem: Despite the wide range of new dental materials, there is still a need for biomaterials demonstrating high biocompatibility, antimicrobial effects and ideal mechanical properties. Purpose: The aim of this study was to histologically evaluate the pulpal response to a conventional glass ionomer, a resin modified glass ionomer and a calcium hydroxide in human teeth. Materials ...

BACKGROUND The biocompatibility of resin-modified glass ionomers (RMGIs) as a lining material is still under question. The present study evaluated the response of the pulp-dentin complex following application of resin-modified glass-ionomer cement, calcium hydroxide and conventional glass-ionomer in deep cavities prepared in human teeth. MATERIALS AND METHODS In this controlled clinical trial...

objective: the aim of this study was to investigate the translucency of resin-modified glass-ionomer cements (rmgic) and polyacid-modified composite resin (pcmr) over a period of one year. materials and methods: the study was done on three rmgic (fuji ii lc, photac-fil aplicap and vitremer) and one pcmr (dyract). a conventional gic (fuji cap ii) and two composite resins (tetric and z 100) were ...

background: the clinical success of sandwich technique depends on the strength of resin-modified glass ionomer cement (rmgic) bonding to both dentin and resin composite. therefore, the shear bond strength (sbs) of resin composite bonded to rmgic utilizing different resin adhesives versus a gic-based adhesive was compared. materials and methods: in this in vitro study, 84 holes (5×2 mm) were pre...

Direct pulp capping is the most conservative restorative procedure for protecting the pulp from further insult, permitting healing and repair. Calcium hydroxide Ca(OH) 2 is the most commonly used materials for direct pulp capping . The aim of this study was to compare clinically and radio graphically Ca(OH) 2 with Resin modified glass ionomer (RM-GIC) as a direct pulp capping material. Forty si...

This study visually compared the radiopacity of seven restorative materials (3 resin-modified glass-ionomer cements, 3 polyacid-modified composite resins, and 1 conventional glass-ionomer cement) to a sound tooth structure sample, and an aluminium stepwedge. All hybrid materials were more radiopaque, except for one resin-modified glass-ionomer cement, than both the tooth structure and conventio...

AIM The aim of this in vitro study was to evaluate the microleakage of the new glass ionomers ChemFil Rock and IonoluxAC in comparison to Fuji IX GP Extra and the composite Aelite LS Posterior in permanent teeth. MATERIALS AND METHODS Class V standardised U-shaped cavities were made on a total of 40 freshly extracted teeth and restored with different glass ionomer materials (4 groups of 10 sa...

OBJECTIVE To investigate and compare the amount of fluoride release of conventional, resin modified and nanofilled resin modified glass ionomer cements. MATERIALS AND METHODS Tablets of glass-ionomer cements were immersed in deionized water and incubated at 37°C. After 1, 2, 7, 15 and 30 days, fluoride ion was measured under normal atmospheric conditions by fluoride ion selective electrode. B...

Light cured glass ionomer cements offer improved handling characteristics. Photocuring within the cavity preparation may assist in decreasing the moisture contamination and dehydration difficulties associated with the early stage of setting reaction. The success of restoration depends on good adhesion between glass ionomer cement and the tooth structure. Various dentin conditioners have been ad...

BACKGROUND The aim of this study was to investigate the effect of polyethylene fiber on diametral tensile strength of conventional and resin modified glass ionomer cements. MATERIAL AND METHODS 60 specimens in 6 groups (n=10) were prepared. In group 1 conventional glass ionomer (Fuji GC) and in group 2 resin modified glass ionomer (Fuji LC) were as control groups. In group 3 and 4 conventiona...
