TLDR
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.Abstract:
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.read more

Particles and molecules in endodontic leakage.
H. W. Kersten,W. R. Moorer +1 more
TL;DR: Investigation to find out to what degree obturation prevents leakage of bacteria-sized particles or large protein molecules, and if leakage of the commonly used dye methylene blue is comparable with that of a small bacterial metabolic product of similar molecular size.

Biocompatibility of dental materials used in contemporary endodontic therapy: a review. Part 2. Root-canal-filling materials.
C. H. J. Hauman,Robert M. Love +1 more
TL;DR: This paper is a review of the biocompatibility of contemporary orthograde and retrograde root-canal-filling materials.

An Analysis of the Release and the Diffusion Through Dentin of Eugenol from Zinc Oxide-Eugenol Mixtures
TL;DR: In human teeth in vitro containing ZOE as a base or temporary filling, peak eugenol release at the pulpal surface of dentin was of the order of a thousand-fold less than that at the salivary surface, and this appears to provide a basis for the explanation of the paradox of the therapeutic and toxic actions of ZOE.

In Vitro Apical Leakage of System B Compared with Other Filling Techniques
Ludovic Pommel,Jean Camps +1 more
TL;DR: A fluid filtration system was used to compare the apical microleakage of roots filled with the system B, single-cone technique, lateral condensation, vertical Condensation, and Thermafil, and five groups of 10 single-rooted teeth were randomly filled according to 1 of the 5 techniques.

The pharmacologic and toxicological properties of zinc oxide-eugenol
Wyatt R. Hume,Wyatt R. Hume +1 more
TL;DR: An explanation of the therapeutic effects and toxic effects of zinc oxide-eugenol when placed in contact with intact or carious dentin is presented to allow for the rational, safe, and effective use of the material.

Dental Silicate Cements. I. The Chemistry of Erosion
TL;DR: It is shown that cement erosion, the chemistry of which has been little studied, possesses certain unique features and Estimates of cement durability, by in vitro studies conducted over 3 weeks in which erosion was measured by chemical analysis, agreed well with clinical opinion.

A comparison of the intraoral disintegration of three dental cements
TL;DR: This research established a procedure for measuring the intraoral disintegration of dental cements and used the technic for in vivo studies of zinc phosphate, silicate, and zinc oxide-eugenol cements.

The Effect of Certain Additive Agents on the Physical Properties of Zinc Oxide-Eugenol Mixtures:
Ralph W. Phillips,Dwain R. Love +1 more
TL;DR: A review of the literature reveals that certain manufacturing processes for zinc oxide powder and the use of various additive agents may improve certain physical properties of zinc oxide-eugenol cements, such as setting time and strength, yet they may simultaneously have a deleterious effect on other desirable properties such as solubility as discussed by the authors.

The reaction of metal oxides with o-ethoxybenzoic acid and other chelating agents.
TL;DR: A large portion of this report deals with the products obtained from mixtures of zinc oxide with o-ethoxybenzoic acid (EBA) because they appeared to be the most promising.

Dental Silicate Cements: III. Environment and Durability
TL;DR: In this article, it was shown that phosphates are important constituents of the gel matrix of dental silicate cements and that they show little dissolution in the pH range associated with normal saliva but are drastically attacked by acids and citrates.
