Microstructure and mechanical properties of composite resins subjected to accelerated artificial aging.
The aim of this study was to investigate the influence of accelerated artificial aging (AAA) on the microstructure and mechanical properties of the Filtek Z250, Filtek Supreme, 4 Seasons, Herculite, P60, Tetric Ceram, Charisma and Filtek Z100. composite resins. The composites were characterized by Fourier-transform Infrared spectroscopy (FTIR) and thermal analyses (Differential Scanning Calorim...
متن کاملColor Stability of Three Composite Resins following Accelerated Artificial Aging: An In-Vitro Study
Received: 27 April 2013 Accepted: 6 August 2013 Abstract Background and Aim: Discoloration is among the most common problems of composite restorations. Color change over time compromises the main advantage of composite resins namely their high esthetics. In such cases, the restoration needs to be replaced. .The aim of this in-vitro study was to evaluate the effect of accelerated artificial agin...
متن کاملEvaluating the Color Change of Different Types of Composite Resins Subjected to Zoom!® in-Office Bleaching
Beauty is a combination of qualities that delight the sight, other senses or the mind. Today, because of recent introduction and production of materials science and sophisticated dental techniques, better esthetics & improved durability of a restoration is achieved. It was found that color maintenance throughout the functional lifetime of restorations which is an indicator for the durability of...
متن کاملeffect of accelerated artificial aging on translucency of methacrylate and silorane-based composite resins
objectives: composite restorations must have tooth-like optical properties namely color and translucency and maintain them for a long time. this study aimed to compare the effect of accelerated artificial aging (aaa) on the translucency of three methacrylate-based composites (filtek z250, filtek z250xt and filtek z350xt) and one silorane-based composite resin (filtek p90). materials and methods...
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 ...
