Clinical Studies of Dental Cements: III. Seven Zinc Oxide-Eugenol Cements Used for Temporarily Cementing Completed Restorations

¹ School of Dentistry, University of Michigan, Ann Arbor, Michigan 48104

Seven zinc oxide-eugenol cements with compressive strengths from 200 psi to 8,000 psi were used for temporarily cementing completed inlays, crowns, and bridges. The effectiveness of each cement in a variety of clinical situations is presented. Cement of 1,000 psi met the requirements of typical clinical cases most frequently. The cements of compressive strength 200, 400, 600, 2,200, and 3,500 psi were required in other clinical cases with sufficient frequency to justify their use.
