Release of antimicrobial compounds from a zinc oxide-chelate cement

The diffusion of glutaraldehyde from zinc oxide-eugenol cement.

The diffusion of glutaraldehyde from zinc oxide and eugenol cement (ZOE) into water was measured. The egress was found to be substantial and correlated to the amount of glutaraldehyde which was incorporated initially. The percentages of the fixative which diffused from the ZOE preparations containing 2,5, or 10% glutaraldehyde were virtually identical, demonstrating that there is no restriction...

Release of cetyl pyridinium chloride from fatty acid chelate temporary dental cement

Objective To determine whether the antimicrobial nature of a fatty acid chelate temporary dental cement can be enhanced by the addition of 5% cetyl pyridinium chloride (CPC). Materials and methods The temporary cement, Cavex Temporary was employed, and additions of CPC were made to either the base or the catalyst paste prior to mixing the cement. Release of CPC from set cement specimens was fol...

Catalytic effects of metal chelate compounds.

This paper is essentially a progress report on the developments in the field of metal chelate catalysis since the first review of this subject fifteen years ago'. For the purpose of defining the scope of this field, metal chelate catalysis is considered to include any reaction that is altered or modified by metal ions through chelate ring formation, as well as reactions of metal chelates themse...

Investigation of the antimicrobial effect of silver doped Zinc Oxide nanoparticles

The antimicrobial effect of metal nanoparticles such as zinc oxide and silver nanoparticles has been taken into great consideration separately during recent years. The useful application of these nanoparticles in the areas of medicine, biotechnology, and professional prevention of microbes motivated us. The aim of this study was to evaluate antibacterial activity properties of silver doped zinc...
