Background and Aim: Data regarding the efficacy of universal adhesives are limited. This study aimed to assess the durability of a universal adhesive bond to superficial dentin using etch and rinse and self-etch modes. Materials and Methods: In this in vitro, experimental study, 32 sound molars were randomly divided into two groups of Scotchbond Universal adhesive with two-step etch and rins...

This in vitro study investigated the influence of using different combinations of bracket, adhesive, and light-curing source on the tensile bond strength to porcelain and on failure patterns at debonding. Tensile tests were performed using: one ceramic bracket versus one metal bracket, two orthodontic composites; type bisphenol A-glycidyldimethacrylate and urethane dimethacrylate (UDMA), and fo...

OBJECTIVES This study aimed to compare the micro-tensile bond strength of methacrylate resin systems to a silorane-based restorative system on dentin after 24 hours and six months water storage. MATERIAL AND METHODS The restorative systems Adper Single Bond 2/Filtek Z350 (ASB), Clearfil SE Bond/Z350 (CF), Adper SE Plus/Z350 (ASEP) and P90 Adhesive System/Filtek P90 (P90) were applied on flat ...

Three types of direct-bonding metal bases were used to determine the effect of five commercial surface treatments on in vitro tensile bond strength. The proprietary treatments were etching, silanation, surface activation, etching plus silanation, and etching plus surface activation. Nontreatment was used as a control. The bases were of the mesh, photo-etched, and grooved types. Bases were loade...

one of the most important applications of carbon nanotubes (cnts) is as reinforcement of metal matrix composites, because of their excellent mechanical properties. in this study, al-tio2-multi walled carbon nanotubes (mwcnts) nanocomposite is fabricated using isostatic pressing followed by hot extrusion. mechanical alloying is used to mix powders of aluminium, tio2 and mwcnts. tio2 with the amo...

This study was a clinical trial of a one-step, total priming and bonding system, Xeno III. Thirty restorations were placed in minimally invasive V-shaped, Class V cervical cavities. Immediately after placement, baseline records were made after restorations were assessed using modified Ryge/USPHS criteria. Subsequently, restorations were evaluated at recall intervals up to 18 months. Additionall...
