Zinc Oxide-Eugenol Cements: IV. Microstructure and Hydrolysis

Journal of Dental Research, 1973
The microstructure of zinc oxide-eugenol cement and the water-leached product was examined by electron microscopy and scanning electron microscopy. Crystalline zinc eugenolate, which forms a reaction product, encases and binds unconsumed zinc oxide grains.

The effect of zinc oxide eugenol cement on penicillin

American Journal of Orthodontics and Oral Surgery, 1946
Abstract 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-

Zinc Oxide-Eugenol Cements: II. Study of Erosion and Disintegration

Journal of Dental Research, 1970
The 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.

Pulp reaction to a temporary zinc oxide/eugenol cement

Journal of Prosthetic Dentistry, 1976
The pulpal irritation, such as inflammatory reaction and aspiration of pulpal cells, demonstrated after insertion of the zinc oxide/eugenol cement (Nobetec) seems to warrant the following recommendations: (1) A temporary restoration with a zinc oxide/eugenol base should not be inserted in deep cavities without a protective liner or a calcium hydroxide ...

Pulpal response to a zinc oxide–eugenol cement

International Endodontic Journal, 1987
Summary. The British Standards Institution have produced a recommended testing procedure for toxicity of dental materials; this advocates the use of a zinc oxide—eugenol cement such as Kalzinol, as a bland control in deep cavities. In this study, Kalzinol was applied directly to the exposed pulps of germ‐free rat molar teeth.

Effect of Fluoride-Containing Zinc Oxide-Eugenol Cements on Solubility of Enamel

Journal of Dental Research, 1970
The 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. No change in solubility was observed when fluoridefree zinc oxide-eugenol cements were used.

Root canal fillings with zinc oxide-eugenol cement in the rat molar

Oral Surgery, Oral Medicine, and Oral Pathology, 1967
Abstract The histologic response of periapical tissues to root canal fillings with zinc oxide-eugenol cement was studied in the lower molars of rats. Root canal fillings were placed in normal teeth of 141 Wistar rats, and the animals were killed at different postoperative periods ranging from 24 hours to 90 days. Semiserial sections of each specimen

Zinc Oxide Non-Eugenol Cement versus Resinous Cement on Single Implant Restoration: A Split-Mouth Study [PDF]

Journal of Composites Science, 2023
Cement-retained implant restorations still represents a widely used prosthetic solution today, considering the simple execution, the possibility of correcting the implant axis according to the dental axis and an extremely satisfactory aesthetic.

Zinc oxide and eugenol cements for permanent cementation

The Journal of Prosthetic Dentistry, 1968
Abstract A group of zinc oxide and eugenol cements designed for permanent cementation were compared to zinc phosphate cement on the basis of compressive strength, tensile strength, solubility, and film thickness. In addition, the amount of tensile force required to remove standardized gold inlays from the prepared cavity when they were cemented with ...
