Six-month evaluation of a resin/dentin interface created by methacrylate and silorane-based materials
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 ...
متن کاملComparative Evaluation of Bond Strength and Microleakage of Standard and Expired Composite at Resin-Dentin Interface: An in vitro Study
BACKGROUND Evaluation of bond strength and microleakage caused by polymerization shrinkage provides a screening mechanism and an indication of the potential for the clinical success of composite restorations. AIM The aim of this study was to determine the effect on shear bond strength and microleakage of standard and expired composites. MATERIALS AND METHODS Selected specimens were etched u...
متن کاملExposed Dentin: Influence of Cleaning Procedures and Simulated Pulpal Pressure on Bond Strength of a Universal Adhesive System
PURPOSE To compare various pre-treatments serving as cleaning procedures of dentin on the bond strength of resin composite promoted by a universal adhesive system applied either in the absence or presence of simulated pulpal pressure. MATERIALS AND METHODS Prior to application of the adhesive system (Scotchbond Universal) and resin composite (Filtek Z250), ground dentin surfaces were given on...
متن کاملEffect of Using Electric Current during Dentin Bonding Agent Application on Microleakage under Simulated Pulpal Pressure Condition
BACKGROUND The use of electric current during application of etch-and-rinse adhesive systems has been recently introduced to decrease microleakage. This study investigated the effects of an electric field produced by an experimental device for the application of a two-step etch-and-rinse adhesive on moist dentin surface. METHODS Sixty freshly extracted human premolars were used for this study...
متن کاملInterfacial microscopic examination and chemical analysis of resin-dentin interface of self-adhering flowable resin composite
Background: The newly introduced self-adhering flowable resin-composites decrease the required time for application by incorporation of an acidic adhesive monomer, thus reducing the number of steps, but its bonding is still uncertain. The aim of this study was to evaluate the interfacial microscopic examination and chemical analysis at the resin-dentin interface of a self-adhering flowable resi...
