Microtensile bond strength of bulk-fill restorative composites to dentin
BACKGROUND To facilitate the easier placement of direct resin composite in deeper cavities, bulk fill composites have been introduced. The Mechanical stability of fillings in stress bearing areas restored with bulk-fill resin composites is still open to question, since long term clinical studies are not available so far. Thus, the objective of the study was to evaluate and compare the microtens...
متن کاملPush-Out Bond Strength of Restorations with Bulk-Fill, Flow, and Conventional Resin Composites
The aim of this study was to evaluate the bond strengths of composite restorations made with different filler amounts and resin composites that were photoactivated using a light-emitting diode (LED). Thirty bovine incisors were selected, and a conical cavity was prepared in the facial surface of each tooth. All preparations were etched with Scotchbond Etching Gel, the Adper Scotchbond Multipurp...
متن کاملA Comparative Study of Shear Bond Strength of Bulk-Fill Composites, Packable and Flowable, as Well as Conventional Light-Curing Composite
Introduction: This study aimed to compare the Shear Bond Strength (SBS) of two bulk-fill composites versus a conventional resin composite. Materials and Methods: In this study, 60 sound extracted human premolars were selected and sectioned horizontally from one-third of the coronal crown to expose dentin using a low-speed cutting saw. The dentin bonding agent was applied to all specimens, then...
متن کاملMicroleakage of Bulk-Fill Composites at Two Different Time Points
Objectives: Microleakage is the main concern in composite restorations. This study aimed to compare the microleakage of two bulk-fill and one conventional composite at two different time points. Methods: Class II cavities were prepared in 60 premolar teeth and divided into six groups of 20. Groups 1 and 4 were incrementally filled with Grandio composite. Groups 2 and 5 were filled with X-tra...
متن کاملPre-heating of high-viscosity bulk-fill resin composites: effects on shrinkage force and monomer conversion.
OBJECTIVES To investigate the influence of pre-heating of high-viscosity bulk-fill composite materials on their degree of conversion and shrinkage force formation. METHODS Four bulk-fill composite materials (Tetric EvoCeram Bulk Fill-TECBF, x-tra fil-XF, QuixFil-QF, SonicFill-SF) and one conventional nano-hybrid resin composite (Tetric EvoCeram-TEC) were used. The test materials were either k...
