The surface roughness and gloss of composites.
The contrast gloss and the average roughness were measured for four commercial composite filling materials. Using a factorial design, each material was subjected to four available finishing methods. A significant difference was found in the contrast gloss among finishing methods, and a significant linear regression is given which relates the inverse of the contrast gloss to the average roughnes...
متن کاملPorcelain surface roughness, color and gloss changes after orthodontic bonding.
The purpose of this study was to evaluate the alteration in surface characteristics after orthodontic debonding of two types of porcelain systems commonly used in prosthetic dentistry. For this purpose, porcelain specimens were fabricated from low-fusing (n = 20) and high-fusing (n = 20) porcelain. The baseline surface roughness, color, and gloss were evaluated using profilometry, color shade i...
متن کاملColor stability, gloss, and surface roughness of indirect composite resins.
This in vitro study evaluated the color stability, gloss, and surface roughness (Ra) of four indirect composites. Enamel and dentin shades of Radica, Sculpture Plus, Belleglass-NG, and Gradia Indirect were evaluated for color stability. Specimens were stored in a staining solution (coffee) and assessed every 3 days for a period of 21 days, after which color difference (∆E*) was calculated. Only...

©2005, IS&T—The Society for Imaging Science and Technology pigment particle size distribution, particle shape, binder type, film shrinkage, drying conditions, coating holdout, and coating weight.6 Research groups studying the roughness and its effect on gloss have agreed upon the fact that common roughness numbers are insufficient to predict gloss.9 It sometimes occurs that the rougher surfaces...
متن کاملThe effects of surface gloss and roughness on color constancy for real 3-D objects.
Color constancy denotes the phenomenon that the appearance of an object remains fairly stable under changes in illumination and background color. Most of what we know about color constancy comes from experiments using flat, matte surfaces placed on a single plane under diffuse illumination simulated on a computer monitor. Here we investigate whether material properties (glossiness and roughness...
