Background and Objective: The colored compomers are a group of restorative materials that are introduced for filling of primary dentition since 2002. These materials have been used in pediatric dentistry because of their attractive colors and their simple handling properties. But their characteristics have not been evaluated and compared completely. Since a change in the color of these material...
in this study, the fatigue behavior of alloy steels with different hardness values was tested. results showed that the fatigue limit increases by the increment of hardness up to 400 vickers whereas it drops when the hardness value exceeds 400 vickers. fractographic observations using scanning electron microscopy revealed non-metallic inclusions as the dominant fatigue crack initiation sites. by...
a sustained-release tablet formulation should ideally have a proper release profile insensitive to moderate changes in tablet hardness that is usually encountered in manufacturing. in this study, matrix aspirin (acetylsalicylic acid) tablets with ethylcellulose (ec), eudragit rs100 (rs), and eudragit s100 (s) were prepared by direct compression. the release behaviors were then studied in two co...
