EFFECTS OF RESIDUAL MERCURY ON STRENGTH, FLOW, AND DIMENSIONAL CHANGE OF DENTAL AMALGAM

摘要

Although amalgam still remains the most commonly used restorative material and a vast amount of laboratory and clinical research concerned with its use has been published, there are still many practical problems that remain unanswered. One of these is the consistency, or actually the mercury content, of each increment which is inserted into the cavity preparation during the condensation procedure. It is generally recognized that the residual mercury content of the restoration will influence tarnish and strength. However, the dryness of the individual increments which are used to build the restoration remains a controversial issue.
