Vaporization of Hg from Hg-In amalgams during setting and after abrasion

摘要

Objective: The aim of this study was to determine if Hg vaporization during setting and after abrasion of amalgams could be reduced by adding indium to Hg prior to trituration. Methods and materials: hg-In alloys (0, 5, 10, 15 wt/100 In) were triturated with commercial amalgam alloys (Tytin, Kerr; Arrtalloy, Degussa: Sybraloy, Kerr) and condensed into cylinders (4 × 8 mm). In one experiment, Hg release during setting was measured in air (37 deg. C) with a Jerome 431 Hg analyzer (n = 4).
