Individual records on amalgam filling placements were available. The cohort was followed up from 1977 to 1997 and linked with cancer registrations and hospital admissions. Hazard ratios (risk associated with 100 amalgam-filled-surface-years, relative to the risk associated with having no amalgam ...
9.04.6.2.1Filling materials Dentalamalgamhas been a main filling material for comparatively small defects in a tooth. It consists mainly of an Ag–Sn (–Cu) alloy powder andHg liquid, and they together form a hard substance by amalgamation. The composition of the alloy powder is specified in...

The surface of the silver was either polished or burnished. To examine local contact creep and the effect of surface finishing, we used an indentation creep method in which a Vickers indenter was loaded on the specimen surface at a load of 10 N with dwell times of 5 sec to 6x10(4) ...
One theory, based on the assumption that they leave the surface contribution unaffected but change the inner work function by causing the density of the solvent to increase, is quantitatively successful. 展开 关键词: mercury (metal) work function/ A7200 Electronic transport in condensed matter ...
Furthermore, when the cements were combined with different thicknesses and with different amalgam Young’ s modulus values, it was concluded that 50 GPa causes less stress on restoration surface. Keywords: amalgam; finite element analysis; resin cement; glass ionomer cement; stress distribution...
