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

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 ...

Zinc oxide and eugenol cements for permanent cementation
The Journal of Prosthetic Dentistry, 1968Abstract 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 ...

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.

Concentration of eugenol apically released from zinc oxide-eugenol-based sealers
Journal of Endodontics, 1999This 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

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.

Temporary zinc oxide–eugenol cement: eugenol quantity in dentin and bond strength of resin composite
European Journal of Oral Sciences, 2013Uptake of eugenol from eugenol‐containing temporary materials may reduce the adhesion of subsequent resin‐based restorations. This study investigated the effect of duration of exposure to zinc oxide–eugenol (ZOE) cement on the quantity of eugenol retained in dentin and on the microtensile bond strength (μTBS) of the resin composite. The ZOE cement (IRM

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.

Root perforations dressed with calcium hydroxide or zinc oxide and eugenol
Journal of Endodontics, 1987Root perforations were experimentally made at the furcation level in 15 maxillary and mandibular dog's premolars. A group of these perforations were dressed with an aqueous paste of calcium hydroxide and iodoform; another group was dressed with zinc oxide and eugenol; and in a third group (control) the perforations were kept open.

Some Physical Properties of Zinc Oxide-Eugenol Impression Pastes
The Journal of the American Dental Association, 1950These 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.
