Effect of water storage on fluoride release and mechanical properties of a polyacid-modified composite resin (compomer)
We evaluated the effect of water storage on fluoride release and mechanical properties of compomer restorative material. Fluoride release was recorded using a specific fluoride electrode. Flexural properties and fracture toughness were measured using a universal testing machine. Vickers hardness was measured using a micro-hardness tester. There was initial burst of fluoride release up to 1 w, w...
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 کاملmicroleakage comparison of polyacid composite resin restorations and resin modified glass ionomer before and after ultrasonic scaling
introduction: in different investigations, the destructive effect of ultrasonic scalers on the margins of composites has been studied, but there are very few studies on the effects of ultrasonic scalers on the microleakage of poly-acid modified composite resin and resin modified glass ionomers. the main purpose of this study was to evaluate the marginal microleakage of class v preparations rest...
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 کاملArgon-Ion Laser Vs Quartz-Tungsten-Halogen Curing of Polyacid Modified Composite Resin Restorative Materials
Recently, there has been an interest in using an argon laser to initiate polymerization of light-activated materials [11]. The argon laser, the active medium of which is argon gas, produces light at two wavelengths. The 488 nm blue light is commonly used to initiate the polymerization of restorative composite materials. The 514 nm blue green light has maximum absorbance in tissues that are comp...
