Methods: Resin-modified glass ionomer (Vitremer – V), microhybrid composite resin with fluoride (Tetric Ceram – T), and nanofiller composite resin without fluoride (Z350 – Z) were evaluated. Acidulated phosphate fluoride (APF, 1.23%) was applied to half of the specimens (groups VF, TF, ZF and EF). Ten intact human third molars were used to obtain enamel specimens (E). Six experimental groups (n...

objectives: the aim of this study was to evaluate the effect of six herbal teas on the color stability of two types of nanohybrid and one microhybrid resin composite.  materials and methods: 70 disc-shaped specimens, 210 in total (7*2mm), were fabricated from each of the following materials in metal mould : tetric n ceram, grandio, gradia direct anterior. specimens were stored in distilled wate...

BACKGROUND Casein phosphopeptide-amorphous calcium phosphate (CPP-ACP) is applied for remineralization of early caries lesions or tooth sensitivity conditions and may affect subsequent resin bonding. This in vitro study investigated the effect of CPP-ACP on the shear bond strength of dental adhesives to enamel. MATERIALS AND METHODS Sixty extracted human molar teeth were selected and randomly...

BACKGROUND: It is known that the development of carious process promoted by microorganisms secrete waste products penetrate into tooth tissue during depressurization filling material. That why high-quality restoration prevents secondary caries.
 AIM: Based on study edge fit restorations made various types materials, when restoring chewing surface tooth, to determine most optimal method fil...

The influence of three curing modes of a high-powered LED curing unit on temperature rise under 2-mm-thick dentin was investigated during the polymerization of resin composite samples of Admira, Filtek P60, Premise, Tetric Flow, Tetric Ceram, and Filtek Z250. Ninety standard specimens were prepared. The bonding agents and resin composites were cured with standard, pulse, or soft-start mode (n=5...

OBJECTIVE The purpose of this study was to investigate the effects of two curing light intensities on the mechanical properties (Vickers microhardness, compressive strength, and diametral tensile strength) of bulk-fill resin-based composites (RBCs). MATERIALS AND METHODS Four commercially available bulk-fill RBCs (Tetric® N-Ceram, SonicFill™, Smart Dentin Replacement (SDR™) Posterior Flowable...

INTRODUCTION The ultimate goal in restorative dentistry has always been to achieve strong and permanent bond between the dental tissues and filling materials. It is not easy to achieve this task because the bonding process is different for enamel and dentin-dentin is more humid and more organic than enamel. It is moisture and organic nature of dentin that make this hard tissue very complex to a...

INTRODUCTION The aim of this study was to assess the wear resistance of four bulk-fill composite resin restorative materials cured using high- and low-intensity lights. MATERIALS AND METHODS Twenty-four samples were prepared from each composite resin material (Tetric N-Ceram, SonicFill, Smart Dentin Replacement, Filtek Bulk-Fill) resulting in a total of 96 samples; they were placed into a mol...

Objective: The purpose of this study was to investigate the surface finish of 5 different aesthetic restorative materials after polishing with 3 different polishing systems. Materials and Method: The materials included 2 nano-filled composites (Tetric Evo Ceram and Grandio), a compomer (Compoglass F), a resin-modified glass ionomer cement (Fuji II LC), and a highly viscous glass-ionomer cement ...
