OBJECTIVES The aim of this study is to compare the success rate obtained when applying either a calcium hydroxide (Dycal) base or a zinc oxide-eugenol (Kalzinol) base following the traditional ferric sulfate pulpotomy. METHODS Patients were either treated in the chair or under general anaesthesia. All teeth had to have radiographic evidence of caries close to the pulp. After haemostasis was a...

Alveolar osteitis is the most common post operative sequel to tooth extraction. It occurs despite the most exacting operative technique, aseptic procedure and regardless of the ability of surgeons. Various packing materials are available for topical treatment of alveolar osteitis. Purpose: The present study was conducted to evaluate and compare the effectiveness of Zinc Oxide Eugenol dressing, ...

The aim of this study was the comparative evaluation of inflammatory reactions and tissue responses to four growth factors, or mineral trioxide aggregate (MTA), or a zinc-oxide-eugenol-based cement (IRM) as controls, when used for the repair of furcal perforations in dogs' teeth. Results showed significantly higher inflammatory cell response in the transforming growth factorβ1 (TGFβ1) and zinc-...

It has been accepted traditionally that the setting of zinc oxide-eugenol (ZOE) cements is the result of the formation of zinc eugenolate crystals.1 A recent study pointed out that at least seven hours elapsed before zinc eugenolate crystals precipitated from a clear solution of zinc acetate in eugenol.2 Accelerated ZOE, however, set in as short a time as three minutes.3 Electron microscopy, el...

Objective. The objective of this study was to evaluate the efficacy of two retreatment NiTi systems (protaper universal retreatment files, R-Endo), when compared to manual technique in removing Gutta-percha obturated with two sealers. Study Design. Sixty extracted single-rooted premolars were instrumented with Protaper rotary files till F3. The specimens were divided into six groups. Groups 1, ...

PURPOSE This investigation collected clinical and radiographic data from a retrospective chart review of patients receiving ferric sulfate pulpotomies with a sub-base of zinc oxide eugenol in a clinical practice over a five-year period. METHODS AND MATERIALS Clinical and radiographic data were available for 242 primary molars in 171 children with follow-up times ranging from 4-57 mos (mean = ...

Eugenol has antifungal activity and is recognised as having therapeutic potential. However, little is known of the cellular basis of its antifungal activity and a better understanding of eugenol tolerance should lead to better exploitation of eugenol in antifungal therapies. The model yeast, Saccharomyces cerevisiae, expressing apoaequorin was used to show that eugenol induces cytosolic Ca(2+) ...

OBJECTIVES Epilepsy establishment gives rise to biochemical and morphological changes in the hippocampus. Oxidative stress, morphological changes, and mossy fiber sprouting (MFS) in the hippocampus underpin the epilepsy establishment. Eugenol is the main component of the essential oil extracted from cloves with the potential to modulate neuronal excitability. Therefore, we investigated the effe...

There has been great interest in intervention strategies based on plant essential oils to control pathogens such as Escherichia coli O157:H7 and Listeria monocytogenes (Lm). However, the poor solubility of essential oils in water makes it difficult to disperse evenly in food matrices, impacting food quality and antimicrobial efficacy. In the present study, eugenol was dispersed in nanocapsules ...
