Thermal Analysis of Zinc Oxide-Eugenol Cements During Setting

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...

Setting Reaction of Zinc Oxide and Eugenol !

Physical properties of some 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...

Solubility of zinc oxide-eugenol and calcium hydroxide cements in simulated dentinal fluid.

The solubility of four dental cement bases was measured in simulated dentinal fluid and distilled water to evaluate the relevancy of the American Dental Association solubility test for cement bases in contact with vital dentine. A simulated dentinal fluid was formulated utilizing glucose, distilled water, and sterile human plasma. Cement-base samples were immersed in either distilled water or s...
