Zinc oxide eugenol has the bottom compressive and tensile strength on the liners, so its use is restricted to tiny or non-stress-bearing places which include Class V cavities.

Zinc oxide eugenol may be used as linings in deep cavities without having producing harm towards the pulp, as a consequence of its obtundant impact on the pulp as well as its bactericidal properties as a result of zinc.
