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...
متن کاملIn vitro toothbrushing abrasion of dental resin composites: packable, microhybrid, nanohybrid and microfilled materials.
This study evaluated weight loss and surface roughening after toothbrushing of different resin composites: one packable (Solitaire 2, Heraeus Kulzer), one microhybrid (Charisma, Heraeus Kulzer), one nanohybrid (Simile, Pentron) and one microfilled (Durafill VS, Heraeus Kulzer). Cylindrical specimens (n = 20) were prepared. Half of the samples were submitted to 60,000 strokes, at 4 Hz, with a de...
متن کاملSTRENGTH AND FRACTURE TOUGHNESS OF WHISKER REINFORCED DENTAL RESIN-BASED COMPOSITES
Enhancing the properties of dental resin composites is of interest to researchers. The objective of the present investigation was to improve the strength and fracture toughness of dental composites via addition of silicon carbide whiskers and substitution of commonly used filler materials with stabilized zirconia ceramic powder. It was also intended to study the effect of powder- to- whisker ra...

متن کاملEffect of different light-curing techniques on hardness of a microhybrid dental composite resin
Objective: This study assessed the Vickers hardness (VHN) provided by two LCUs when using (1) direct and indirect light-curing techniques, (2) 40 and 60 s and (3) top and bottom surfaces. Material & Methods: One halogen Curing Light 2500 (3M Espe) and one LED (MM Optics) were used by direct and indirect (0, 1.0, 2.0 and 3.0 mm of dental structure) techniques during 40 and 60 s. The samples were...
