Clinical Studies of Dental Cements: I. Five Zinc Oxide-Eugenol Cements

Clinical studies of dental cements. I. Five zinc oxide-eugenol cements.

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 inf...

Clinical 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...

Clinical studies of dental cements. II. Further investigation of two zinc oxide--eugenol cements for temporary restorations.

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...

Thermal analysis of zinc oxide-eugenol cements during setting.

It has been accepted traditionally that the setting of zinc oxide-eugenol (ZOE) cements is the result of the formation of zinc eugenolate crystals.1 A recent study pointed out that at least seven hours elapsed before zinc eugenolate crystals precipitated from a clear solution of zinc acetate in eugenol.2 Accelerated ZOE, however, set in as short a time as three minutes.3 Electron microscopy, el...
