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 purpose of the present study was to evaluate morphologically the response of feline teeth pulp to direct pulp capping with two different self-etch adhesive systems. Twenty-four cavities in feline teeth were mechanically exposed and assigned to one of two experimental groups: AdheSE + Tetric Ceram (the ASE group), or Adper Prompt L-Pop + Filtek Supreme (the APLP group). There was also a cont...

PURPOSE To investigate the microtensile bond strength between two all-ceramic systems; lithium disilicate glass ceramic and zirconia core ceramics bonded with their corresponding glass veneers. MATERIALS AND METHODS Blocks of core ceramics (IPS e.max® Press and Lava™ Frame) were fabricated and veneered with their corresponding glass veneers. The bilayered blocks were cut into microbars; 8 mm ...

Aim: Composite resins contain different monomers and fillers that are directly affected by polymerization shrinkage. Therefore, an accurate reliable method is needed to measure the volume changes. The aim of this study was evaluate amount change associated with shrinkage in four bulk-fill composite materials class II restorations using a micro-CT device, which has high resolution provides 3-dim...

This study evaluates the repair bond strength of resin-matrix and glass-matrix CAD/CAM ceramic materials based on two systems. Thirty specimens measuring 2.5 mm in thickness were prepared from Crystal Ultra (CU), Vita Enamic (EN), Lava Ultimate (LU), Cerasmart (CS), Vitablocs Mark II (VM2) aged for 5000 thermal cycles. Specimens randomly allocated into three groups: control, Monobond-S (MS) pri...

BACKGROUND Microbial contamination of the pulp space is one of the major factors associated with endodontic failure. Thus, in addition to a three dimentional apical filling a coronal seal for root canal fillings has been recommended. AIM The present study was conducted to evaluate and compare the intra-orifice sealing ability of three experimental materials after obturation of the root canal ...

ÖZET Amaç: Kompozit malzemelerin sıklıkla yapısında yer alan BIS-GMA, polimerizasyondan sonra reaksiyona girmeden kalabilmektedir. Artık monomerlerin bilinen zararlı etkileri nedeniyle, dental malzemelerden salınan monomer miktarlarının belirlenmesi çok önemlidir. Mevcut çalışmanın amacı, kompozit rezin, akışkan ve bulk fill materyallerden BIS-GMA değerlendirilmesidir. Gereç yöntemler: Toplamda...

Introduction: The aim of this study was to compare a one-year clinical performance of two composites (Ariston PHC with Tetric) in class II cavity preparations. Materials & Methods: Ninety-six class I and II modified cavity preparations in identical patients were prepared. Metallic matrix was used for restoration of class II preparations. Ariston PHC and Tetric were used for restorations. The cl...

The aim of this study was to evaluate relationship between shrinkage development and early solubility of two commonly used luting materials, a self-adhesive cement (GCem chemical and light cured) and composite resin (Tetric). Linear displacement, shrinkage forces and leaching of UDMA from specimens immersed in 75% ethanol/25% water were measured. The least amount of linear shrinkage (33.0±2.9 µ...
