STATEMENT OF PROBLEM Fracture of a repaired denture base often occurs at the junction of the base and repair materials rather than within these materials. PURPOSE The purpose of the study was to evaluate the shear bond strengths of 4 denture base acrylic resins following the use of 3 chemical solvents and to examine treated acrylic resin surfaces under a field emission scanning electron micro...

UNLABELLED The purpose of this study was to evaluate and compare the effect of grit blasting, chemical treatment, and application of alloy primer combinations on the shear bond strength (SBS) of a self-cure resin cement to titanium surface. MATERIALS AND METHODS Fifty cast commercially pure titanium discs (9 mm × 2 mm) were divided into five groups (n = 10), which received the following surfa...

In this study, the concrete-steel bond strength of concrete filled cylindrical steel tubes has been experimentally investigated. 22 short, high strength and normal concrete filled circular steel tubes were tested. Push-out test was carried out as the common method to evaluate the bond carrying capacity. Four different concrete mixes were used in preparing the specimens. The steel tubes were w...

in this work, the strength of cold roll bond of the commercially pure titanium (cp ti) sheet and the effect of tio2 nanoparticles on bond strength was investigated. through the accumulative roll bonding process, which is considered among the important severe plastic deformation processes, the creation of suitable bonds plays a significance role in the ultimate strength of the bond. thus, resear...

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...

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...

introduction: the aim of this in vitro study was to evaluate the effect of canal dryness on the push-out bond strength of two resin sealers (ah-plus and adseal) and a bioceramic sealer (endosequence bc sealer) after canal irrigation with sodium hypochlorite (naocl) and chlorhexidine (chx). methods and materials: a total of 18 extracted human premolars were used. canals were prepared and were di...

this in-vitro study sought to assess the push-out bond strength of a total etch and 2 self-etch bonding systems to intracanal dentin of primary anterior teeth (pat).thirty-six primary anterior teeth were randomly divided into 3 groups of 5(th) generation (single bond 2), 6(th) generation (clearfil se) and 7(th) generation (single bond universal) bonding agents. the canal orifice was restored wi...
