The influence of some manipulative factors on creep

The effects of a number of factors on creep in dental amalgam was investigated. The factors studied were the delayed time between mixing and packing, the packing technique, the alloy system and the annealing or ageing of specimens at 37 degrees C for one and 190 days. The delayed time and the alloy system factors as well as an interaction between them had a significant influence on the one day annealed specimens. The alloy system in the 190 days annealed specimen was the only factor to affect creep.
