EndodonticsAn ideal root canal sealer should have all the mentioned properties: 1) Fills the space between cone and canal walls - primary mechanical function, 2) Should have antibiotic properties - to eliminate residual bacteria and prevent reinfection, 3) Should be biologically acceptable - biocompatible with periapical tissues, non-toxic, and non-irritating, 4) Additional ideal properties include: dimensional stability, easy mixing and placement, radiopacity, and easy removal if retreatment needed. No current sealer meets all ideal requirements completely, but these remain the goals for sealer development.

When mercury comes in contact with the
alloy powder (mainly silver, tin, copper):
Mercury first dissolves the outer surface of the alloy particles.
After dissolution, new reaction products begin to form:
Ag–Hg (gamma-1 phase) from reaction with silver
Sn–Hg (gamma-2 phase) from reaction with tin (in low-copper amalgam)
Cu–Sn (eta phase) replaces gamma-2 in high-copper amalgam
