Composition and physical properties of a polycarbonate resin-reinforced zinc oxide-eugenol cement and of a formulation based on zinc oxide, eugenol and o-ethoxybenzoic acid (EBA) were determined. Both materials were similar in strength, but the polycarbonate-containing material was tougher and showed less solubility and disintegration. Cementing film thicknesses were obtained with the EBA cement.
