Application of bis-eugenol to a zinc oxide eugenol cement

Journal of Dentistry, 1999
To 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.

Eugenol release and the cytotoxicity of different zinc oxide-eugenol combinations

Journal of Dentistry, 1988
The relationship between the toxicity and release of eugenol from different zinc oxideeugenol (ZOE) combinations was examined in this study in vitro using the model cavity method. Both eugenol release and toxicity were higher from conventional ZOE mixtures than from mixtures using a reinforced zinc oxide powder.

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.

Concentration of eugenol apically released from zinc oxide-eugenol-based sealers

Journal of Endodontics, 1999
This study investigated the amount of eugenol released from a zinc oxide-eugenol-based sealer at the apex of teeth filled according to two techniques: the single-cone and the Thermafil. The crown of 10 maxillary central incisors was removed, and the canal was prepared with ProFile to a size 30 under NaOCl irrigation. The patency of the apex was checked

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.

Cytotoxicity of eugenol in sealer containing zinc‐oxide

Dental Traumatology, 1991
Abstract In this study two zinc‐oxide‐based root canal sealers were compared for their tissue toxic response. The sealers tested were zinc‐oxide eugenol and zinc‐oxide glycerine. Fifteen albino rats were used for the study and were injected subcutaneously in the preset state.

Dielectric Properties of Zinc Oxide-Eugenol Type Cements

Journal of Dental Research, 1974
Relative 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, 1982
An 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

Some Physical Properties of Zinc Oxide-Eugenol Impression Pastes

The Journal of the American Dental Association, 1950
These preparations which have been dis­ cussed require considerable cutting with either steel, diamond or carborundum disks and wheels. The cutting must be precise. Therefore, it is often necessary to use a local anesthetic so that the pa­ tient’s discomfort will be minimized.

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-
