Comparing the Microleakage of Bulk-Fill (flowable, packable) Composite Restorations and Conventional Light-cured Composites
Introduction and aim: Bulk Fill composites have increased polymerization depth and their contraction stress, and cuspal deflection are reduced in comparison with conventional composites. Therefore, it is claimed that their microleakage is reduced. The aim of this study was to compare microleakage of (flowable and packable) Bulk Fill and conventional resin composites. Materials and Methods: Thi...
متن کاملRelation between conversion degree and cytotoxicity of a flowable bulk-fill and three conventional flowable resin-composites.
OBJECTIVE The aim of this study is to evaluate if the cytotoxic effects of the Surefil SDR flow, bulk fill flowable composite resin and three conventional flowable materials (Venus Diamond Flow, Filtex Supreme XTE Flowable and Enamel plus HRi Flow) correlated with the conversion degree (DC); hardness and depth of cure are also assessed. MATERIALS AND METHODS Disks of each materials--cured usi...
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 کاملDegree of Conversion and BisGMA, TEGDMA, UDMA Elution from Flowable Bulk Fill Composites.
The degree of conversion (DC) and the released bisphenol A diglycidyl ether dimethacrylate (BisGMA), triethylene glycol dimethacrylate (TEGDMA) and urethane dimethacrylate (UDMA) monomers of bulk-fill composites compared to that of conventional flowable ones were assessed using micro-Raman spectroscopy and high performance liquid chromatography (HPLC). Four millimeter-thick samples were prepare...
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...
