Jamilian A, Parhiz H, Rastegariyan H, Nobakht S. Efficacy of three Disinfectants on Alginate Impressions. Iranian Journal of Orthodontics. 6, 1 (2011/6):32-37
Background and Purpose: Dental impressions often carry microorganisms that may cause cross infection from patients to dental staff. The purpose of this study was to evaluate the disinfecting efficacy of three commercially available disinfectants on Staphylococcus aureus.
Methods and subjects: Impressions were made of a sterile metal model of the maxillary arch that had been contaminated with Staphylococcus aureus. The Impressions were cultured before and after immersion in one of the following disinfectants: 15 minutes in Micro 10⁺ (5%), 5 minutes in Deconex (2%) and 10 minutes Glutaraldehyde (2%).
Results: Kruskal-Wallis test was used to evaluate the colony forming units (CFUs) of Staphylococcus Aureus.in each of the three groups. The same test showed that the colony forming units (CFUs) were reduced to Zero by all disinfectants.
Conclusion: This study showed that all disinfectants were fully successful in complete removal of Staphylococcus Aureus.
