introduction: in recent dentin adhesive systems etching of enamel/dentin are achieved simultaneously. the objective was to evaluate the microleakage of composite restorations using single bond2 (5th generation), clearfil s3 bond and g bond (7th generation). methods: class v cavities were prepared on  45 extracted intact premolars with gingival margins at the cementoenamel junction and they were...

There is a growing consensus that the benefits of information technology (IT) can not be realised fully by merely automating existing business processes. Consequently, major process changes enabled by IT, including business process re-engineering efforts, have been popular in North America and are now being introduced all over the world. Differences between nations and societies make it critica...

The wetting behavior of poorly conducting fluids between two parallel conducting plates is studied, both, theoretically and experimentally. In the absence of an applied potential, the interface shape and height are determined by gravity and parameterized using the Bond number. In the presence of an electric field at sufficiently high values on the order of (1 kV/mm), there is modification of th...

background: the aim of this study was to compare the shear bond strength of four one-step self-etch adhesives with different ph values to enamel and dentin. materials and methods: in this in vitro study, 200 bovine permanent mandibular incisors were used. four one-step self-etch adhesives with different ph values were tested both on enamel and on dentin: adper™ easy bond self-etch adhesive (ph ...

statement of problem: the bond strength between restorative material and tooth structure is so important for conduction of durable restoration. considering the recent attention to low shrinkage composite resins, evaluation of micro tensile bond strength of these materials would be valuable. objectives: to compare the microtensile bond strength of silorane composite resin (filtek p90) with the c...

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...
