PURPOSE This study was to evaluate the effect of the solution temperature on the mechanical properties of dualcure resin cements. MATERIALS AND METHODS For the study, five dual-cure resin cements were chosen and light cured. To evaluate the effect of temperature on the specimens, the light-cured specimens were immersed in deionized water at three different temperatures (4, 37 and 60℃) for 7 d...

BACKGROUND There are a number of studies citing the primary reason for replacing auto cure glass ionomer cements was due to recurrent caries. The purpose of this study was to use an in vitro model to measure caries at the dentine restoration interface of bonded composite resin and auto cure glass ionomer cement restorations and to measure the amount of surface degradation occurring in the resto...

Purpose. To investigate the effect of light activation on the water sorption (WS) and solubility (SL) of resin cements after 24 h and 7 days. Methods. Disk-shaped specimens were prepared using five dual-polymerized cements (four self-adhesive [RelyX Unicem, MaxCem, SeT and G-Cem] and one conventional [Panavia F 2.0]) and divided according to the curing mode (direct light exposure or self-cure) ...

objective: resin cements, regardless of their biocompatibility, have been widely used in restorative dentistry during the recent years. these cements contain hydroxy ethyl methacrylate (hema) molecules which are claimed to penetrate into dentinal tubules and may affect dental pulp. since tooth preparation for metal ceramic restorations involves a large surface of the tooth, cytotoxicity of thes...

BACKGROUND Glass ionomer cements are widely used in pediatric practice due to their advantage of fluoride release and chemical bond to tooth structure. Adherence of the restorative material to the cavity walls is one of the most important characteristic for it to be proven as an ideal material as it prevents microleakage. AIMS AND OBJECTIVES This study was aimed at evaluating the microleakage...

The retention of zirconia-based ceramic posts (CosmoPost system) luted with glass ionomer and resin cements was evaluated. Thirty-two extracted, caries-free, unrestored teeth were selected and stored in chlorhexidine and water solution. The teeth were endodontically treated and randomly assigned to two groups (n=16). Each tooth was decoronated and prepared to a depth of 10.0 mm from root surfac...

Purpose: Scientific data on wear from toothbrushing of luting cements for fixed partial dentures (FPDs) are limited and inconsistent, therefore the study aimed: (1) to investigate the effect of marginal gap width on cement wear and (2) to compare the resistance to wear from toothbrushing of five luting materials in an in vitro model. Materials and Methods: one zinc phosphate cement (ZPC), glass...

Glass ionomer cements (GICs) are widely used in restorative dentistry.1 In dentistry, one of their advantages over other restorative materials is that they can be placed into tooth cavities without an additional bonding agent.2 They also possess a fluoride-releasing property3 and are relatively biocompatible with the pulp.1 Adhesive property and fluoride release of glass ionomer cement contribu...

In recent years, calcium silicate cements have been introduced. The purpose of this study is to analyze the main differences between silicate-based and epoxy resin-based cements, analyzing scientific literature last year highlight advantages for predictable clinical use. Data collected from included studies were used in order different features: chemical-physical properties, cytotoxicity cell m...
