Zinc oxide eugenol has the lowest compressive and tensile energy from the liners, so its use is limited to tiny or non-worry-bearing places such as Course V cavities. This cavity lining is commonly employed by using a substantial strength base to offer toughness, rigidity and thermal insulation. Zinc oxide eugenol can be used as linings in deep cavities devoid of leading to hurt to your pulp, as a result of its obtundant effect on the pulp along with its bactericidal Houses due to zinc.

The main downside of GICs is lack of satisfactory power and toughness. To improve the mechanical Homes of the standard GIC, resin-modified ionomers have been marketed.
