Fluoride Release from Conventional Glass-ionomer Cements and Polyacid-modified Composite Resins
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...
متن کاملSurface hardness properties of resin-modified glass ionomer cements and polyacid-modified composite resins.
In this study the top and bottom surface hardness of two polyacid-modified composite resins (PMCRs), one resin-modified glass ionomer cement (RMGIC), and one composite resin were evaluated. The affect of water storage on their hardness was also investigated. The study was conducted using four different groups, each having five specimens obtained from fiberglass die molds with a diameter of 5 mm...
متن کاملAntibacterial activity of glass-ionomer restorative cements and polyacid modified composite resin against cariogenic bacteria.
The dental plaque harbours a diverse range of bacteria such as Streptococcus mutans, Streptococcus sanguis, Streptococcus sobrinus, Lactobacillus spp, Actinomyces spp. etc, embedded in a matrix of polymers of bacterial and salivary origin. Therapeutic procedures used in the treatment of caries do not always eliminate all the microorganisms in the residual tissues, leading to development of recu...
متن کاملDo conventional glass ionomer cements release more fluoride than resin-modified glass ionomer cements?
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,...
متن کاملComparison of the Amount of Fluoride Release from Nanofilled Resin Modified Glass Ionomer, Conventional and Resin Modified Glass Ionomer Cements
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...
