## Abstract From 0 to 24 hours at an initial static stress of 34.5 MPa and in the temperature range of 0 to 60Β°C, the creep behavior of four different oneβweekβold dental amalgams was monitored in a recently developed minispecimen creep apparatus. In most instances the behavior could not be describ
## Abstract Equipment is described which enables the determination of the creep behavior of small specimens of dental amalgam under tensile stresses. The apparatus has been used to measure the creep strain of both low and high copper dental amalgams at 34Β°C, in the stress range 9.4 to 38.8 MNm^β2^,
## Abstract The wear of dental amalgam was studied by singleβ and doubleβpass sliding and by a silicon carbide abrasion test. A dispersed amalgam showed significantly better resistance to twoβbody abrasion than the spherical amalgams tested. The wear of amalgam was determined by resistance to penet
