Composites Associated with Pulp-Protection Material: Color-Stability Analysis after Accelerated Artificial Aging
OBJECTIVES This study assessed the color stability of two composites associated with two pulp protectors submitted to accelerated artificial aging (AAA). METHODS 60 test specimens were made with 0.5 mm of protection material (calcium hydroxide - CH or glass ionomer cement - GIC) and 2.5 mm of restoration material (Concept or QuixFil) and divided into 3 groups (n=10) according to the type of p...
متن کاملColor stability of modern composites subjected to different periods of accelerated artificial aging.
The aim of this study was to evaluate the color stability of composites subjected to different periods of accelerated artificial aging (AAA). A polytetrafluorethylene matrix (10 x 2 mm) was used to fabricate 24 test specimens of three different composites (n=8): Tetric Ceram (Ivoclar/Vivadent); Filtek P90 and Z250 (3M ESPE), shade A3. After light activation for 20 s (FlashLite 1401), polishing ...
متن کاملEffects of fibers on the color change and stability of resin composites after accelerated aging.
Composite resins were reinforced with glass and polyethylene fibers in this study, and the effect of fiber reinforcement on the color change of composite resins was investigated. After accelerated aging, the effect of fiber reinforcement on the color stability of composite resins was also examined. There were three experimental groups (n=12 disks per group): non-fiber-reinforced composite (non-...
متن کاملEffects of different polishing methods on color stability of resin composites after accelerated aging.
The purpose of this study was to evaluate the effect of polishing procedures on the color stability of different types of composites after aging. Forty disk-shaped specimens (Ø10×2 mm) were prepared for each composite resin type (an ormocer, a packable, a nanohybrid, and a microhybrid) for a total of 160 specimens. Each composite group was divided into four subgroups according to polishing meth...
متن کاملColour Stability of Veneering Composites after Accelerated Aging
OBJECTIVES To investigate the colour stability of four indirect composite restorative materials after accelerated aging. METHODS Four indirect composites (Gradia, Signum+, HFO and Adoro) were used. For each material, six specimens were prepared and subjected to accelerated aging (Suntest CPS+, Atlas, Chicago, IL, USA) according to ISO 7491. A Dr. Lange Microcolor Data Station colorimeter (Bra...
