This study investigated weight changes of seven different light-cured composite restorative materials, one polyacid glass ionomer compomer, and one light-cured glass-ionomer cement following short-term and long-term storage in water. Two packable composites, three universal (hybrid) composites, one microglass composite, one polyacid glass ionomer resin composite (compomer), one microhybrid low-...

Background and purpose: Antibacterial properties of restorative materials are of great advantage as they control the progression of tooth decay. The use of self-adhesive composite materials has some benefits such as easier application and reduced treatment time. Because the antibacterial properties of restorative materials can play an important role in preventing secondary decay, especially in ...

The release of fluoride from glass ionomer materials is one of the most important features of this newly implemented material, and the remineralization effects of this phenomenon have been documented (Hicks and Silverstone 1986). This paper examines the effects of glass ionomer/silver cermet restorations on the plaque levels of interproximal mutans streptococci. Fifteen patients with Class II l...

Background: Fluoride-releasing restorative materials are often selected because of the anti-caries effect that has been reported as a result of their fluoride release. Much of this effect has been reported as it relates to remineralization. Less work has been performed looking at the potential of fluoride released from glass-ionomer cements (GICs) to have an effect on cariogenic bacteria direct...

BACKGROUND Conventional caries removal involves use of high-speed handpiece. Current concepts of caries excavation in cavitated lesions consist of manual excavators. Principles of minimal invasive approach indicate the need to excavate only carious tissue. AIM The aim of this study was to compare the microleakage in conventional and resin modified glass ionomer cement restorations following c...

Glass ionomer cements (GIC) are known as a non-bioactive dental cement. During setting the GIC have an acidic pH, driven by the acrylic acid component. It is a challenge to make GIC alkaline without disturbing its mechanical properties. One strategy was to add slowly reacting systems with an alkaline pH. The aim of the present study is to investigate the possibility of forming a bioactive denta...

Previous studies indicated that toxic components can be released from glass ionomer cements and diffuse through dentinal tubules into the pulp. This in vitro study compared the cytotoxic effects produced to pulpal fibroblasts by the leachables of the primer systems and the diffusates through dentin of four resin-reinforced glass ionomer cements (Vitremer Tri Cure System, Dyract-Prime & Bond 2.0...

The effect of Active Screen Plasma Nitriding (ASPN) treatment on the surface-cellular compatibility of an inert aluminosilicate glass surface has been investigated. ASPN is a novel surface engineering technique, the main advantage of which is the capacity to treat homogeneously all kind of materials surfaces of any shape. A conventional direct current nitriding unit has been used together with ...
