## Abstract The integrated peak intensities of certain reflections of the ฮณ, ฮณ~1~ and ฮณ~2~ phase of six dental amalgams at a mercury content of 45 wt% were selected and their dependence on the annealing time (1 < __t__ < 140 days) at 37ยฐC was determined. Also the overall changes in phase compositio

## Abstract A dimensional change occurs during the setting of a dental amalgam. A measurement circuit, which makes it possible to register these changes, is introduced. To this purpose strain gages were used. The registration instrument is tested by comparing different dental amalgam products.
There are many controversies about the long-term prognosis of hydroxyapatite (HA)-coated implants. Failure may be related to compositional and structural changes of the coating occurring during implantation. Two retrieved and two unused HA-coated blade-type implants were examined by stereomicroscopy
