Residual HEMA and TEGDMA Release and Cytotoxicity Evaluation of Resin-Modified Glass Ionomer Cement and Compomers Cured with Different Light Sources
The purpose of this study was first to evaluate the elution of 2-hydroxyethyl methacrylate (HEMA) and triethylene glycol dimethacrylate (TEGDMA) monomers from resin-modified glass ionomer cement (RMGIC) and compomers cured with halogen and light-emitting diode (LED) light-curing units (LCUs). The effect of cured materials on the viability of L929 fibroblast cells was also evaluated. One RMGIC (...
متن کاملcomparing fluride release in conventional glass ionomer, light-cured glass ionomer and compomers
current study is aimed to compare fluride release in conventional glass ionomer, light-cured glass ionomer and compomers. standard samples from the aforementioned materials were prepared and measured by selective fluride ion electrode in intervals of 24hours, 1,2,3 and 4 weeks in neutral ph of 7 and acidic ph of 4.5. the obtained data represented that fluride ion release decreased in time but t...
متن کاملBond strength of orthodontic light-cured resin-modified glass ionomer cement.
The purpose of this study was to compare the bond strengths and debonded interfaces achieved with light-cured resin-modified glass ionomer cement (RMGIC) and conventional light-cured composite resin. In addition, the effects of acid etching and water contamination were examined. One hundred human premolars were randomly divided into five equal groups. The mini Dyna-lock upper premolar bracket w...
متن کاملMicroleakage Evaluation of Class II Composite Resin Restorations with Different Thicknesses of Resin-Modified Glass Ionomer
Background and Aim: One of the weaknesses of Class II composite resin restorations is gingival microleakage which contributes to postoperative sensitivity and secondary caries. The aim was to evaluate the microleakage in Class II composite resin restorations with different thicknesses of resin-modified glass ionomer (RMGI). Materials and Methods: In this in-vitro study, standardized Class II s...
متن کاملComparative evaluation of antibacterial effect and compressive strength of resin-modified glass-ionomer containing different antibiotics
Background and Aims: Nowadays, new techniques are used to control dental caries that have the ability to kill cariogenic bacteria. Recently, the addition of antibiotics to glass ionomers has been proposed to reduce the overall number of saliva bacteria. The aim of this study was to compare the antimicrobial effect and compressive strength of resin- modified glass ionomer (RMGI) containing diffe...
