title: Effects of lining materials on shear bond strength of amalgam and gallium alloy restorations.
abstract: In this in vitro study, where alloys were condensed into unset paste lining materials, shear bond strengths were significantly greater than with the unlined controls. The use of varnish or Paama 2 linings did not significantly increase the shear bond strength of amalgam or gallium alloy restorations. The use of Vitrabond, Vitremer, or Resinomer liners significantly increased the shear bond strength compared to unlined restorations. Permite C restorations lined with Resinomer all showed cohesive failure within the mixed alloy/ liner. Of the unlined restorations, Permite C had significantly higher shear bond strength than Lojic Plus. The experimental method used in the present study proved to be suitable for quantitative comparison of the shear bond strength of different dental materials.
