objective: zinc oxide eugenol (zoe) under composite restorations should be covered with a suitable material in order to prevent the harmful effect of zoe on the composite. the aim of this in vitro study was to evaluate microleakage of composite restorations in pulpotomized primary molars with different bases for covering the zoe layer and to assess the distance between different layers. materia...

The repellent activity of monoterpenoids viz. eugenol, zimtaldehyde and neem oil against pulse beetle, Callosobruchus maculatus (F.) was investigated. Responses varied significantly with compound, dose and exposure time. The tested components showed highest level of repellency against C. maculatus at a dose of 1 μl. Over 80%, Class V, repellency was achieved after 5 to 60 min. treatment with th...

Eugenol derivatives (3a-f) were synthesized under microwave irradiation in aq KOH by reacting different aromatic acid chlorides (2a-f) with Eugenol. The newly synthesized compounds were confirmed by spectral analysis and evaluated for antimicrobial activity. Some compounds showed promising activities.

The effects of oral environment stabilization procedures on counts of Candida spp. have rarely been discussed, and no conclusive results are found in the literature. The aim of this study was thus to ascertain the effects of oral environment stabilization procedures with glass ionomer and zinc oxide-eugenol cements on counts of Candida spp. in the oral cavity of children. For this purpose, oral...

Aim: The emergence of nosocomial infections, which are mainly transmitted by contaminated instruments, there is an urgent need of a novel disinfecting agent, which can able to act by the novel method with less residual concentration. Evaluation of antibacterial activity of thymol-eugenol mixture for potential application as disinfectant agent. Methods: The reference strains of Escherichia coli,...

Carvacrol and eugenol, the main (phenolic) components of essential oils of some aromatic plants, were evaluated for their therapeutic efficacy in the treatment of experimental oral candidiasis induced by Candida albicans in immunosuppressed rats. This anticandidal activity was analyzed by microbiological and histopathological techniques, and it was compared with that of nystatin, which was used...

BACKGROUND We recently reported that eugenol exerted comparable cytotoxicity towards human normal and tumor cells. In the present study, we investigated the effect of eugenol on interleukin-8 (IL-8) production by IL-1β-stimulated oral cells. MATERIALS AND METHODS The viable cell number was determined by direct cell counting with a hemocytometer after trypsinization. IL-8 released into the cul...

Results: All materials tested demonstrated different degrees of sorption and solubility. The glass ionomer cement had the best value for sorption. The zinc oxide eugenol and eugenol free cements had lower water sorption than the zinc polycarboxylate and zinc phosphate cements were evaluated. Some materials retained water in their structure and thus compensated for any loss of mass due to dissol...

BACKGROUND Excessive production of free radicals has been implicated in many diseases including cancer. They are highly reactive and bring about oxidation of biomolecules i.e., proteins, lipids and nucleic acids which are associated with many degenerative diseases. Natural products acting as antioxidants have ability to neutralize free radicals and their actions and hence they mitigate their ha...
