Monomer Release from Nanofilled and Microhybrid Dental Composites after Bleaching
OBJECTIVE The aim of this study was to assess the effect of bleaching on elution of monomers from nanofilled and microhybrid composites. MATERIALS AND METHODS 80 samples (5mm diameter and 3mm thickness) of each composite were prepared. After curing, half of them were randomly polished. Each group was divided into 8 subgroups and immersed in water or 10%, 20% and 30% H2O2 for 3 or 8 hours. Elu...

OBJECTIVES This study aimed to evaluate the effects of chlorhexidine mouthrinses on color stability of nanofilled and micro-hybrid resin-based composites. MATERIALS AND METHODS In this in-vitro study, 160 disc-shaped specimens (7x2mm) were fabricated of Filtek Z250 and Filtek Z350XT Enamel (A2 shade). The samples of each group were randomly divided into eight subgroups (n=10). The specimens w...

متن کاملMechanical properties of nanofilled and microhybrid composites cured by different light polymerization modes.
This study compared nanofilled and microhybrid composites polymerized by different light polymerization modes, and the effects these modes had on the mechanical properties of the composites. The following mechanical properties were measured: Vickers microhardness numbers, diametral tensile strength, flexural strength, and flexural modulus. The filler content (Wt%) present in the resins was inve...
