چکیده
Zinc oxide-eugenol cements have long been used to cement temporary restorations in teeth prepared for inlays, crowns, or fixed bridges,1'2 and a variety of products is available to the dentist. During the last 25 years, the physical properties of these materials have been studied, and numerous improvements in physical characteristics and manipulative qualities have been achieved.3 't Little information has been available, however, on the clinical behavior of the zinc oxideeugenol cements. No data have been collected that correlate physical properties with the clinical behavior of these cements in the oral environment, and the clinician has relied on his own judgment in the selection of a cement for a particular instance. It has come to be recognized that the compressive strength of a cement has a relationship to its ability to hold a restoration in place; the stronger the cement, the more securely the restoration is retained. For temporary crowns, a cement is required that has sufficient strength to hold a variety of restorations in place but that is not so strong as to make removal of the restoration difficult. This study was an attempt to find the optimum strength for a cement for outing temporary restorations. Clinical evaluation presents difficulties in controlling all the factors involved, the retention quality of the preparation, the adap-

Dental cements: a further update.
The Phenolate Cement Zinc oxide-eugenol cements have always been regarded as the blandest in terms of their effect on the dental pulp. For this reason, these materials were commonly used as the control in biocompatibility pulp research studies on cements and restorative materials. Zinc oxide-eugenol cements have traditionally been used as temporary restoratives because of the sedative effect on...
متن کاملClinical studies of dental cements. 3. Seven zinc oxide-eugenol cements used for temporarily cementing completed restorations.
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 p...

a compressive strength of 2,200 psi and the other with a compressive strength of 3,500 psi, were the most satisfactory for cementing temporary restorations. The data collected, however, were not sufficient in quantity to differentiate between the two cements. There was the possibility that one or the other of the two cements might prove superior, and this investigation was undertaken to collect...

Statement of Problem: Zinc contained cements are so important among dental material as they have many indications and used in different ways therefore evaluation of their physical properties is so important in dentistry.Purpose: The purpose of this research was to measure some physical properties of zinc-contained cements used in restorative dentistry. These cements included: Zinc oxide-eugenol...
