After these steps, the specimens were submitted to different situations: 1. In one study, while comparing UV rays disinfection with Introduction . Major advances in impression materials and their application have occurred during the last decade, with greater emphasis being placed on rubber impression materials than on dental compound, zinc oxide-eugenol, and agar and alginate. However, it has been shown that washing impression materials with water alone removes as little as 40% of bacteria, viruses and fungi5 and therefore is totally inadequate as a means to reduce potential infection Phenols with a high alcohol content, for example, can desiccate some impression materials. did a PubMed search between 1980 and 2005 on the effect of chemical disinfection, by immersions or spraying, on the impression’s dimensional changes. The efficiency of disinfection methods and their adverse effects on the materials are being evaluated since 19743. Because of their material proprieties and handling ... dental– stone interactions, disinfection properties and consequences, dimensional stability, shelf life, color, odor, taste, availability, and clean-up characteristics may contribute to material selection. They stated that there were variations in the Keywords: Disinfection materials, alginate impression, spray method 1. After disinfection, rinse impression well … Introduction erials, and dental laboratories are exposed to different types of pathogenic microorganisms. Storage of the impression and transport to the dental lab 45 10. Of particular interest has been the effect of disinfection solutions on the of alginate impression material, preparing the mouth, making the impression, removal/inspection of the impression, and storage and disinfection. Mechanical mixing of alginate ensures that Selection of impression tray alginate mix is the same each time they are mixed. The In this in vitro experimental study, 66 circular samples of alginate impression material were contaminated with Staphylococcus aureus, Pseudomonas aeruginosa, and Candida albicans fungus. ZOE and compound impressions The aim of this study was to investigate the effect of three different types of disinfectant agents on alginate impression material after 5 and 10 minutes. Impression materials for preliminary impressions 19 3.5. Most of the studies on impression disinfection focused on the dimen-sional changes and surface details3,10,14,15. In 2008, Kotsiomiti et al. spatulation. Impression materials, impression trays, and poured stone cast have been said to be the main source of cross infection between patients and dentists [1].
