title: [Influence of static flow (CREEP) on amalgam hardness. Effect of alloys and measured areas].
abstract: The authors studied the CREEP of 5 amalgam alloys (1 conventional and 4 with high cooper) by the application os static load of 36 MPa in 478 mm specimens, 7 days old. After CREEP test, the samples were included in acrylic resin and Vickers hardness determined by three penetrations for each portion (cervical, medium and occlusal). Samples not submitted to the creep test was used with control. They concluded that no statistic difference was found in creep test but in Vickers test all the studied materials showed different hardness averages. The load application to samples increased the hardness of all the studied materials.
