adequate bond strength between glass ionomer cements and composite resin is necessary for the success of the sandwich technique.this study assessed the micro-shear bond strength of composite resin to glass-ionomer cements (gic) using self-etch adhesives with different ph values.one hundred specimens (6×4×2 mm) were made using fuji ii and fuji ii lc gics and treated with different adhesives as f...

Due to the great importance that antiseptic solutions have on the control and prevention of oral diseases and their influence on the translucence of esthetic restorative materials, the present study evaluated the effect of antiseptic solutions on the translucence of two glass-ionomer cements, Vidrion R and Chelon Fil, at eight time periods. Four antiseptic solutions were used: Listerine, Malvon...

materials used in the body, especially the materials used in various oral cavity regions should be stable and passive without any interactions with the body tissues or fluids. dental amalgam, c omposite resins and dental cements are the materials of choice with such properties. the first attempts to produce active materials, which could interact with the human body tissues and fluids were promp...

The aim of this in vitro study was to investigate three different cements for their suitability provide semi-permanent cementation, and compare the retention forces implant-supported single crowns (SC) three-unit fixed dental prostheses (FDP) luted with these cements. Twenty-four methacrylate models were supplied implants/abutments each simulate condition SCs/FDPs. Cobalt-chromium frameworks fa...

AIM OF THE WORK Aim of the work was to execute a review of the international literature about the cementation of zirconia restorations, analyzing the properties of the cements most commonly used in clinical activities. MATERIALS AND METHODS It was performed, through PubMed, a bibliographic search on the international literature of the last 10 years using the following limits: studies in Engli...

Objective: To compare the cytotoxicity level of a new calcium silicate-based resin cement (TheraCem) with two commonly used cements, including conventional self-adhesive (Panavia SA) and resinmodified glass ionomer (FujiCem2), on human gingival fibroblast cells after 24 48 hours. Material Methods: Twelve discs each type were fabricated. The extract disks was made by incubating them in cell medi...

OBJECTIVES The main objective is the characterization of the setting reaction in glass ionomer cements (GICs) based on experimental glasses using the (27)Al magic angle spinning nuclear magnetic resonance (MAS-NMR) spectroscopy in order to understand the crosslinking process during the setting reaction. METHODS Three types of GICs which are based on fluoro-alumino-silicate glasses (LG125, ART...
