Effects of palladium addition on emission of mercury vapor from dental amalgam

摘要

Objectives: The purpose of this investigation was to test the hypothesis that palladium causes a reduction in mercury emission when added to dental amalgam during condensation. Methos: Mercury vapor release was measured in a closed bottle system and an Intraoral Flow device (IOF). Conventional amalgam Restorations were modified by addition of various palladium pellets. 1.57 mm diameter palladium pellets with different porosities were Fabricated. These pellets were then placed in amalgam restorations using typical condensation and carving procedures.
