The purpose of this study was to evaluate the genotoxic potential of components leached from two conventional self-curing glass-ionomer cements (Fuji IX and Ketac Molar), and light-curing, resin modified glass-ionomer cements (Vitrebond, Fuji II LC). Evaluation was performed on human lymphocytes using alkaline and hOGG1 modified comet, and micronucleus assays. Each material, polymerised and unp...

for Dental Studies and Research Murad Nagar, Ghaziabad,U.P (M) : 9910113023, E-mail address: [email protected] Abstract Aim: To evaluate the influence of a dual cured composite and resin modified glass ionomer used as a dentin substitute on the microleakage of Class II open-sandwich restorations Materials & Method: Standardized Class II cavities were prepared on 50 extracted human third mo...

dhesive systems associated to resin-modified glass ionomer cements are employed for the achievement of a higher bond strength to dentin. Despite this benefit, other properties should not be damaged. This study aimed at evaluating the short-time fluoride release of a resin-modified glass ionomer cement coated with two one-bottle adhesive systems in a pH cycling system. Four combinations were inv...

OBJECTIVES Fluoride release/recharge properties of fissure sealants are important for their long-term inhibition of caries. This study was conducted to examine the relationship between fluoride release and recharge of pit-and-fissure sealants. METHODS Specimens were prepared from 5 different sealant materials: Fissurit F, a conventional resin; Fuji VII, a glass-ionomer cement (GIC); Fuji II L...

AIM In an effort to control postoperative sensitivity, dentin sealers are being applied following crown preparations, with little knowledge of how crown retention might be affected. A previous study demonstrated no adverse effect when using a gluteraldehyde-based sealer, and existing studies have shown conflicting results for resin-based products. This study determined the retention of the cast...

This study compared the in vitro marginal integrity of open-sandwich restorations based on aged calcium silicate cement versus resin-modified glass ionomer cement. Class II cavities were prepared on 30 extracted human third molars. These teeth were randomly assigned to two groups (n = 10) to compare a new hydraulic calcium silicate cement designed for restorative dentistry (Biodentine, Septodon...

The introduction of air abrasion (sandblasting) technology to orthodontics may allow reaching optimum bond strength between the metal bracket and resin-modified glass ionomer cement. This study examined the effects of sandblasting metal bracket bases on the in vitro tensile bond strength of a resin-modified glass ionomer cement. Two-hundred foil-mesh based brackets were divided into ten groups ...

Fluoride release from six light-activated restorative materials, including two resinmodified glass-ionomers, two composites, and two compomers, was evaluated and compared with one conventional acid-based glass-ionomer cement. The amount and rate of release varied among the tested materials. Both resin-modified glass-ionomers and the conventional acid-base glass-ionomer cements released more flu...

adequate bond strength between glass ionomer cements and composite resin is necessary for the success of the sandwich technique.this study assessed the micro-shear bond strength of composite resin to glass-ionomer cements (gic) using self-etch adhesives with different ph values.one hundred specimens (6×4×2 mm) were made using fuji ii and fuji ii lc gics and treated with different adhesives as f...

PURPOSE The objective of this study was to assess the microleakage of the new conventional glass ionomer, Fuji IXgp in comparison to another conventional glass ionomer (Fuji II), a resin modified glass ionomer (Vitremer) and a composite resin (TPH) in primary and permanent teeth. METHODS Twenty-five extracted human premolars and 13 primary molars were used. Preparations were made on the cente...
