Color 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...

Chromatic stability of acrylic resins of artificial eyes submitted to accelerated aging and polishing

UNLABELLED Esthetics and durability of materials used to fabricate artificial eyes has been an important issue since artificial eyes are essential to restore esthetics and function, protect the remaining tissues and help with patients' psychological therapy. However, these materials are submitted to degrading effects of environmental agents on the physical properties of the acrylic resin. OBJ...

Influence of Light-Curing Units on Color Stability of Composite Resins After Aging

Background and Aim: The use of composite restorations has increased in recent years. One of the most important problems with composite restorations is the loss of consistency between the composite and tooth color, which in most cases requires replacement. Materials and Methods: In this study, the color stability of 40 disc-shaped specimens (10 mm in diameter and 2 mm in height) from two types ...

Color Stability of Two Bulk-Fill Composite Resins

Objective: Bulk-fill composites are a group of composite resins designed for easy and fast filling of large cavities. This study aimed to assess the color stability of bulk-fill composites subjected to xenon radiation and evaluate their color change (&DeltaE) following polymerization. Methods: In this in vitro experimental study, 30 specimens (4mm in height and 8mm in diameter) were fabricat...

Color stability of new composite restorative materials under accelerated aging.

The color stability of seven commercial composite restorative materials under conditions of accelerated aging was evaluated by reflection spectrophotometry at baseline and 300, 600, and 900 h. During early aging the composites generally became darker, more chromatic, and more opaque. Changes in color of the conventional composites during aging were influenced by erosion of the resin matrices an...
