Retentive and Compressive Strengths of Modified Zinc Oxide–Eugenol Cements
Journal of Dentistry, 2000This investigation sought to improve the handling and physical properties of a commonly used temporary zinc oxide-eugenol cement by changing the base/accelerator (B/A) ratio or combining it with a petroleum jelly or fluoride varnish.Twelve modifications of a temporary cement were evaluated in terms of retentive strength, compressive strength at 24 h ...

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.

Pulp reaction to a temporary zinc oxide/eugenol cement
The Journal of Prosthetic Dentistry, 1976The 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 ...

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.

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

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-

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.

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.

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. Semiserial sections of each specimen

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. No change in solubility was observed when fluoridefree zinc oxide-eugenol cements were used.
