Bp. Ng et al., EFFECTS OF SEALERS AND LINERS ON MARGINAL LEAKAGE OF AMALGAM AND GALLIUM ALLOY RESTORATIONS, Operative dentistry, 23(5), 1998, pp. 229-235
In an in vitro study, the use of sealers and liners (Fuji varnish, Vit
rabond, Vitremer, Paama 2, All-Bond 2, or Resinomer) significantly red
uced the amount of marginal leakage around amalgam (Permite C or Lojic
Plus) and gallium (Galloy) alloy restorations. This reduction in marg
inal leakage was produced by all sealers and liners tested, and there
were no statistically significant differences between these materials.
Unlined restorations of Permite C had significantly less marginal lea
kage than Galley or Lojic Plus. Unlined Lojic Plus restorations had th
e greatest amount of marginal leakage. The experimental method used in
the present study proved to be suitable for quantitative comparison o
f marginal leakage of different dental materials.
