The purpose of this in vitro study was to compare the microleakage of occlusal resin composite and three glass ionomer/ resin composite techniques. Class I occlusal preparations were initiated on forty molar teeth. Teeth were randomly assigned to four groups of ten. Groups were restored as follow: 1) Solo Plus / Point 4 resin composite, 2) Fuji IX/ Fuji Bond LC/ Point 4, 3) Fuji IX/ Experimenta...

The purpose of this study is was to compare the color stability alkasite and other restorative materials commonly used in field pediatric dentistry a change response various beverages. Test specimens glass ionomer, resin modified material, composite were prepared, measured after thermocycling. Each specimen also subdivided into 5 groups submerged PBS, coffee, green tea, coke, orange juice analy...

BACKGROUND Streptococcus mutans (ATCC25175) has a profound effect on the incidence of dental decay in the human population. Many studies have been performed to assess the antimicrobial activity of different cements. However, little or no information is available about the antibacterial properties of Type II glass ionomer cement (GIC), Type IX GIC, and AMALGOMER™ ceramic reinforcement (CR). AI...

backgrounds the degree of microleakage is one of the main criteria in evaluating the restorative materials such as glass ionomer (gi) restoratives, which are available in two forms: loose powder and liquid form to be hand-mixed or pre-proportioned in a capsule to be mixed mechanically. objectives this study was conducted to compare the microleakage of encapsulated gi restoratives with their han...

The purpose of this study was to compare the clinical performance of a resin-modified, self-cured glass ionomer adhesive for bonding cast splint Herbst appliances to that of a conventional composite resin in a split-mouth design. Ten patients (six females and four males) with cast splint Herbst appliances were followed for a mean period of 791 months. The performance of 40 cobalt-chromium cast ...

OBJECTIVES This paper collates some of the existing data on the clinical evaluations of resin-modified glass-ionomer cements (RMGICs) since their introduction two decades ago. METHODS The relevant literature was considered and data reviewed under the headings of retention, marginal characteristics, material deterioration, secondary caries, color stability, as well as pulpal and biological eff...

UNLABELLED Attempts have been made to improve the mechanical properties and convenience of use of glass-ionomer cement (GIC) by various modifications, in particular by including a free radical-polymerizable component ("resin-modified" GIC, RMGIC). Necessarily, the one replaces part of the other, but the chemistry suggests that the formation of each network separately would inhibit diffusion and...

A novel furanone derivative and a polyacid constructed from it were synthesized, characterized and formulated into experimental high strength cements. The compressive strength (CS) and Streptococcus mutans viability were used to evaluate the mechanical strength and antibacterial activity of the cements. The effect of human saliva and aging were investigated. The antibacterial activity against L...
