AIM To evaluate the bond strength of one etch-and-rinse adhesive system and one resin-modified glass ionomer cement to sound and eroded enamel. MATERIALS AND METHODS Forty-eight bovine incisors were embedded in acrylic resin and ground to obtain flat buccal enamel surfaces. Half of the specimens were submitted to erosion challenge with pH-cycling model (3x/cola drink for 7 days) to induce ero...

Background and Aim: The aim of the present study was to investigate adhesion ability of resin-modified glass ionomer adhesive (Vitrebond) to ethanol-saturated dentin following two different surface conditioning regimes in term of microtensile bond

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 Home bleaching agents may exert some negative effects on surface hardness of restorative materials such as glass-ionomer cements (GICs). Since some studies have shown that some components such as hydroxyapatite (HA), as a bioactive glass, can improve the mechanical properties of dental materials, the effect of bleaching agents on surface hardness of GICs containing hydroxyapatite is ...

his article describes the properties, advances and shortcomings of glass-ionomer cement as a restorative material. The adhesion of glass-ionomer to tooth structure is less technique sensitive than composite resins and its quality increases with time. Therefore glass-ionomer might turn out to the more reliable restorative material in minimal invasive dentistry based on adhesive techniques. Unite...

PURPOSE The aim of this study was to compare the bonding strength, flexural strength, elastic modulus, water absorption and the expansion after water storage of new self-adhesive resin cements to commercially available dental cements. METHODS Two types (hand-mix and auto-mix) of new self-adhesive resin cements (SAC-H and SAC-A, Kuraray Medical), one conventional resin cement (Panavia F2.0), t...

Fluoride release into deionized water from two glass-ionomer cements (Aqua Ionofil and Ceramfil β) and two polyacid-modified composite resins or compomers (Hytac and Dyract AP) was examined over different time periods. Nine cylindrical specimens (2.5 x 8.5 mm) of each material were prepared and allowed to stand in deionized water. The resulting solutions were analyzed for fluoride by the Alizar...

This randomized clinical trial was carried out to compare post cementation sensitivity in vital abutments of metal-ceramic fixed partial dentures using glass ionomer luting cement and resin based luting cement. It analyzed the results of 182 patients whose records were completed during study duration of 09 months at Department of Prosthodontics, AFID, Rawalpindi. Cold sensitivity tests were use...

OBJECTIVES The aim of this study was to evaluate the fluoride release of conventional glass ionomer cements (GICs) and resin-modified GICs. MATERIALS AND METHODS The cements were grouped as follows: G1 (Vidrion R, SS White), G2 (Vitro Fil, DFL), G3 (Vitro Molar, DFL), G4 (Bioglass R, Biodinâmica), and G5 (Ketac Fil, 3M ESPE), as conventional GICs, and G6 (Vitremer, 3M ESPE), G7 (Vitro Fil LC,...
