Zinc Oxide-Eugenol Cements: II. Study of Erosion and Disintegration
Journal of Dental Research, 1970The continuous leaching of eugenol from zinc oxide-eugenol cements causes the weak zinc eugenolate chelate, which forms the binding matrix, to decompose and the cement to disintegrate. The relevance of specification solubility and disintegration tests is discussed.

The effect of the petroleum jelly on the hardness of Zinc Oxide Eugenol dental cement
Mustansiria Dental Journal, 2018Dental cement is one of few materials which have been developed specifically for dental use, most of the other dental materials have been borrowed from other environment and then modified to meet the particular requirements of dentistry (1).The zinc ...

Characterization of Zinc Oxide-Eugenol Cements Reinforced with Acrylic Resin
Journal of Dental Research, 1972Zinc oxide-eugenol cements reinforced with poly(methyl methacrylate) have significantly higher strength than unmodified formulations. The degree of reinforcement appears to depend on the particle sizes and uniformity of distribution of the resin constituents.

The effect of zinc oxide eugenol cement on penicillin
American Journal of Orthodontics and Oral Surgery, 1946Abstract Penicillin is affected by either eugenol or zinc oxide-eugenol cement. The extent in the reduction of the potency of low- and high-unit concentrations varies. Low-unit dilutions lose most or all of their inhibitory activity towards Staphylococcus aureus , whereas the higher-unit concentrations, though affected, still possess definite growth-

Mechanical mixing of zinc oxide-eugenol cements
The Journal of Prosthetic Dentistry, 1982An analysis of the data yielded the following conclusions: 1. The use of a gelatin capsule in a metal casing combines the advantages of mechanical mixing and those of a disposable system. 2. In comparison to conventional mixing by hand, equal results can be obtained with mechanical mixing. 3. Mixing time and the use of a glass pestle will influence the

Effect of Fluoride-Containing Zinc Oxide-Eugenol Cements on Solubility of Enamel
Journal of Dental Research, 1970The solubility of intact enamel surface was reduced by contact with zinc oxide-eugenol formulations to which sodium fluoride or stannous fluoride was added. The magnitude of the reduction was comparable to that incurred in enamel in contact with silicate cement.

Zinc oxide eugenol cements. VI. Effect of zinc oxide type on the setting reactions
Journal of Biomedical Materials Research, 1982AbstractThe particle size and adsorbed water on zinc oxide from various sources have been investigated and related to the reactivity with eugenol. The reactivity of zinc oxide with eugenol alone increases with the amount of water reversibly adsorbed.

Zinc Oxide-Eugenol Cements: I. The Effect of Atmospheric Conditions on Rheological Properties
Journal of Dental Research, 1969The effect of humidity and temperature during mixing on rheological and setting properties of a number of brands of zinc oxide-eugenol cements has been measured and has been shown to vary among brands. The influence of humidity is discussed in terms of the setting reactions.
