In this study evaluated the effect of different adhesive systems and resin composites on microtensile bond strength repairs using a bulk-fill composite. Ninety specimens were prepared half-hourglass mold composite Filtek Bulk Fill silicone matrix. Specimens randomly distributed in 9 experimental groups (n=10) according to [Universal Single Bond (SBU), Scotchbond Multipurpose Adhesive (SBMP), 2 ...

The aim of this study was to investigate the influence of accelerated artificial aging (AAA) on the microstructure and mechanical properties of the Filtek Z250, Filtek Supreme, 4 Seasons, Herculite, P60, Tetric Ceram, Charisma and Filtek Z100. composite resins. The composites were characterized by Fourier-transform Infrared spectroscopy (FTIR) and thermal analyses (Differential Scanning Calorim...

the aim of this study was to assess the effect of 30% hydrogen peroxide on the microleakage of class v cavities restored with either a silorane-based composite or two methacrylate-based composites.a total of 96 standard class v cavities (1.5 × 2 × 3 mm) were prepared on the buccal surface of sound extracted human premolars with both enamel and dentin margins and randomly assigned into three gro...

OBJECTIVES The aim of this study was to evaluate the effect of pre-etching on the bond strength of silorane-based composite specific adhesive system to dentin. MATERIALS AND METHODS Thirty human molars were randomly divided into 5 groups according to the different bonding strategies. For teeth restored with silorane-based composite (Filtek Silorane, 3M ESPE), the specific self-etching adhesiv...

Introduction: One of the main disadvantages of composites is marginal microleakage using flowable composites as a liner beneath composite restorations has been recommended to reduce microleakage. The aim of this study was to assess the microleakage of class II restorations with different flowable composites liners. Materials & Methods :45 extracted premolars teeth with class II cavity prepar...

BACKGROUND Although most of the studies investigated color stability of different restorative materials, evaluation of color stability of composites after immersion in multiple beverages in the same day by an in vitro oral simulation study is unclear. OBJECTIVE To assess color change of different restorative materials at the end of days 1, 14, and 30 of immersion in multiple liquid types to m...

Significance of Study Mineral trioxide aggregate (MTA) and Biodentine (calcium silicate-based materials) have great importance in dentistry. There is no study comparing the bond strength of Biodentine and MTA for composite, compomer, and compomer or resin-modified glass ionomer (RMGIC). Although many advantages of Biodentine over MTA; in this study, MTA has shown better shear bond strength (SBS...

OBJECTIVE To compare the polymerization effectiveness of two resin composites cured with a quartz tungsten halogen (QTH) lamp or a light emitting diodes (LED) unit. STUDY DESIGN Filtek Z250 (3M ESPE) and Spectrum TPH (Dentsply DeTrey) resin composites were placed in 9 mm deep and 4 mm wide metallic molds and cured using the QTH light Hilux 200 (Benlioglu) or the LED unit Smartlite IQ (Dentspl...
