the effect of 6-month water storage on microleakage of two-component self-etch adhesive systems      dr. mohammadibasir m .,1 dr. seyed tabaii e .2   1 assistant professor, department of operative dentistry , school of dentistry, shahed university. tehran , iran.   2 dentist.     (received 5 dec, 2010 accepted 14 april, 2011)     abstract     background and aim : simplification of the self-etch...

Introdouction: Esthetic demands of patients have led to the introduction of tooth-colored restorations wherecomposite resins are bonded to the enamel using acid etch techniques. Total etch adhesion systems are still considered as the gold standard among bonding systems. However, clinicians have a tendency to use adhesive systems with simpler application procedures. The aim of the present stu...

background: esthetic demands among patients have led to the introduction of tooth-colored restorations. composite resins bond to enamel applying acid etch technique. total etch adhesion systems are still considered as golden standard among bonding systems. however, clinicians have tendency towards using adhesive systems with a simplified application procedure. the aim of the present study is to...

background and aims. studies have shown decreased bond strength of composite resin to human and bovine bleached enamel. this study evaluated the effect of sodium ascorbate and delayed bonding on the bond strength of two adhesive systems to bleached enamel. materials and methods. the labial surfaces of 150 sound bovine incisor teeth were abraded with abrasive paper. the teeth were randomly divid...

BACKGROUND AND AIM: Different studies evaluating one-step self-etch (SE) adhesive systems show contradictory findings, so the aim of this study was to compare the microleakage of one-step SE adhesive systems and CLEARFIL SE BOND (that serves as the “gold-standard” SE adhesive) with low shrinkage composites. METHODS: In this in vitro study, Class V cavities with the occlusal margin in enamel and...

background and aims. the aim was to evaluate the effect of casein phosphopeptide–amorphous calcium phosphate (cpp-acp) on microtensile bond strength (µtbs) to carious affected dentin (cad) using etch-and-rinse and self-etch adhesive systems. materials and methods. the occlusal surface of 32 human molars with moderate occlusal caries was removed. infected dentin was removed until reaching cad an...

objectives: this study aimed to compare the durability of four adhesive systems by assessing their microtensile bond strength (mtbs) and microleakage during six months of water storage. materials and methods: a total of 128 human third molars were used. the adhesives tested were scotch bond multipurpose (sbmp), single bond (sb), clearfil-se bond (cseb), and all-bond se (abse). after sample prep...
