Under challenging oral environments, the overall performance of resin composites is affected by bio-aging. This study investigated effects saliva biofilm-induced bio-aging on mechanical properties and microbial behavior with different filler types. Microhybrid, nanohybrid, nano-filled flowable were bio-aged biofilm for 30 days. Surface morphology, roughness, aesthetic determined. A 48 h model w...

Amaç: Çalışmanın amacı farklı ağız gargara ve antiseptiklerinin kompozit rezinlerin renk stabilitesine etkisini incelemektir. Gereç yöntem: Çalışmada bir mikrohibrit (Filtek Z250, 3M ESPE, St. Paul, MN, ABD) nanohibrit kompozitten Z550, 50’şer adet disk şekilli örnek hazırlandı.

Objective: The purpose of this study was to evaluate the effect two hydrogen peroxide concentrations, commonly used in In-Office bleaching, on surface roughness and color change different esthetic restorative materials. Materials Methods: Sixty disc samples (10 mm diameter 2 thickness) materials were constructed following manufacturers’ instructions. Samples classified into three main groups (n...

OBJECTIVE This in vitro study evaluated the effect of Ankaferd Blood Stopper (ABS) contamination on the microleakage of one-step and two-step self-etching adhesives. STUDY DESIGN Class V cavities were prepared at the cemento-enamel junction on both buccal and lingual surfaces of 60 freshly extracted human molars. Teeth were randomly assigned into three groups according to contamination materi...

OBJECTIVES The purpose of this in vitro study was to compare the centric and eccentric quasi-static and fatigue fracture strength of industrially prefabricated resin-bonded three-unit inlay-retained fixed dental prostheses (IPIRFDPs). The IPIRFDPs consisted of industrial manufactured yttria-stabilized tetragonal zirconia (Y-TZP) frameworks with an industrially added microhybrid composite veneer...

UNLABELLED Chemical substances used during biomechanical preparation of root canals can alter the composition of dentin surface and affect the interaction with restorative materials. OBJECTIVE The purpose of this study was to evaluate the microtensile bond strength (µTBS) of a self-etching adhesive system to dentin irrigated with sodium hypochlorite (NaOCl) and ethylenediaminetetraacetic acid...
