Effect of Aging on Discoloration of Two Composite Surface Sealants
Objectives: Composite surface sealants were introduced aiming to prevent or decrease the discoloration and microleakage of composite restorations. This study sought to assess the effect of aging on discoloration of two composite surface sealants. Methods: In this experimental study, 24 samples were fabricated of Fortify Plus and BisCover LV composite surface sealants (10mm in diameter and 1mm ...
متن کاملAccelerated Heat Aging Study of Phenolic/Basalt Fiber Reinforced Composites
One of the greatest impediments to use polymer-matrix composites is their susceptibility to degradation when exposed to the elevated temperatures and the limited knowledge on the thermal and mechanical properties of these composites at such temperatures. The objective of this study is to evaluate the effects of accelerated heat aging on the tensile properties of the Woven Basalt/Phenolic (WBP) ...
متن کاملPTSD and Accelerated Aging
For hundreds of years, scientists have recognized that the human body is highly sensitive to the external environment. In the mid-1800s, Claude Bernard, who is credited with being among the first to develop and apply scientific methods of experimentation to the study of physiology, suggested that the external environment could alter the “milieu intérieur” (interior environment; Bernard, 1974), ...
متن کاملColor and opacity of composites protected with surface sealants and submitted to artificial accelerated aging
OBJECTIVES To evaluate the color similarity, stability and opacity of composites (TPH, Charisma, and Concept, shade A2) protected with surface sealants (Fortify Plus and Biscover) and cyanoacrylate (Super Bonder). METHODS Forty specimens of each composite were made and separated into 4 groups (n=10) according to the surface protection: GI - without sealant; GII - cyanoacrylate; GIII - Fortify...
متن کاملGPU-accelerated Interactive Material Aging
A photorealistic appearance of a 3D scene is required in many applications today. Thereby, one vital aspect is the usage of realistic materials, for which a broad variety of reflectance models is available. When directly employing those models, surfaces always look new, which contrasts strongly the real objects surrounding us as they have undergone diverse kinds of aging processes. The literatu...
