Pulpal response to a zinc oxide–eugenol cement
International Endodontic Journal, 1987Summary. 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.

Application of bis-eugenol to a zinc oxide eugenol cement
Journal of Dentistry, 1999To assess the usefulness of dimerized eugenol (bis-eugenol) in dentistry, the physical properties of zinc oxide eugenol cement (ZOE) with bis-eugenol and the cytotoxicity of bis-eugenol were studied.Setting time, compressive strength, solubility and disintegration of ZOE cement with bis-eugenol according to the specifications of JDMAS315 were evaluated.

Zinc Oxide-Eugenol Cements: IV. Microstructure and Hydrolysis
Journal of Dental Research, 1973The 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.

Comparison of physico‐chemical properties of zinc oxide eugenol cement and a bioceramic sealer
Australian Endodontic Journal, 2022AbstractThe aim of the present study was to compare the physico‐chemical properties of EssenSeal with AH PLUS bioceramic and Pulp Canal Sealer EWT. Flow, solubility, film thickness, radiopacity and setting time were evaluated according to ISO 6876 (2012) specifications.

Dielectric Properties of Zinc Oxide-Eugenol Type Cements
Journal of Dental Research, 1974Relative permittivity and resistivity of zinc oxide-eugenol cements was measured during setting. During setting the relative permittivity goes through a very pronounced maximum; simultaneously, resistivity suddenly increases by a few orders of magnitude. Such behavior is explicable in the initial function of water, which subsequently becomes bound.

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.

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

Root canal fillings with zinc oxide-eugenol cement in the rat molar
Oral Surgery, Oral Medicine, Oral Pathology, 1967Abstract 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.
