Microcomputed tomographic comparison of posterior composite resin restorative techniques: sonicated bulk fill versus incremental fill.
Sonication technology has recently been touted to decrease composite viscosity during delivery and may allow better cavity preparation adaptation and minimize voids. The purpose of this investigation was to evaluate the difference between conventional, hand-placed, incremental application of a standard hybrid resin-based composite (RBC) and sonicated application of a bulk-fill RBC in box-type a...
متن کاملColor Stability of Two Bulk-Fill Composite Resins
Objective: Bulk-fill composites are a group of composite resins designed for easy and fast filling of large cavities. This study aimed to assess the color stability of bulk-fill composites subjected to xenon radiation and evaluate their color change (&DeltaE) following polymerization. Methods: In this in vitro experimental study, 30 specimens (4mm in height and 8mm in diameter) were fabricat...
متن کاملMicrohardness of Bulk-Fill Composite Materials
The aim of the study was to determine microhardness of high- and low-viscosity bulk-fill composite resins and compare it with conventional composite materials. Four materials of high-viscosity were tested, including three bulk-fills: QuiXfi l (QF), x-tra fi l (XTF) and Tetric EvoCeram Bulk Fill (TEBCF), while nanohybrid composite GrandioSO (GSO) served as control. The other four were low-viscos...
متن کاملthe effect of bulk depth and irradiation time on the surface hardness and degree of cure of bulk-fill composites
statement of problem: for many years, application of the composite restoration with a thickness less than 2 mm for achieving the minimum polymerization contraction and stress has been accepted as a principle. but through the recent development in dental material a group of resin based composites (rbcs) called bulk fill is introduced whose producers claim the possibility of achieving a good rest...
متن کاملLong Term Degree of Conversion of two Bulk-Fill Composites.
OBJECTIVES To investigate the long-term development of the post-cure degree of conversion (DC) for two flowable bulk-fill composites. MATERIALS AND METHODS Tetric EvoFlow Bulk Fill (TEFBF) and SDR were chosen due to their distinct compositional modifications that enable the decrease of translucency during polymerization and lower polymerization rate, respectively. DC was assessed using FT-Ram...
