Preliminary investigation of a method for disinfection of dental impressions. 2009;17(6):565-9. McDonnell G, Russell AD. Review articles are excluded from this waiver policy. Elastomeric impression materials have an elastic or rubber-like quality after setting. In one study, while comparing UV rays disinfection with Glutaraldehyde and NaOCl, UV rays exhibited maximum efficacy.36, The factors affecting the efficacy of NaOCl include concentration and life of solution, pH, temperature and contact time with the impression surface. After contamination, all samples were rinsed with sterile distilled water for 30 seconds. It is also tuberculocidal, fungicidal and virucidal for enveloped viruses as well.14,20,22,23 Alcohols are contraindicated for impression disinfection because they can cause surface changes of impressions.3 They are also not suitable for disinfection of denture bases consisting of non-cross linked resins.24, Phenols: Complex phenols are classified as intermediate level disinfectants. Dent. Antiseptics and disinfectants: activity, action, and resistance. Disinfection of dental impressions by immersion is considered one of the safest methods of disinfection, since literature states that the porosity of dental impression materials leads to the penetration of microorganisms, which disinfection by spray may not effectively destroy. chlorhexidine, NaOCl, H2O2. Using a Pasteur pipet bent with heat at 90 degrees, the samples were spread on cultures. It can be postulated that the use of a more resistant type of bacteria can explain this difference. For information concerning the proper disposal of all disinfected or sterilized waste, please refer to the Generators’ Guide to Hazardous Material / Waste Management. They are not flammable. Three samples were disinfected with Deconex for five minutes and three others for 10 minutes, and three samples were selected for disinfecting with Epimax for five minutes and three others for 10 minutes. 0 In Prac. Disinfection is the process that eliminates many to all pathogenic microorganisms on inanimate objects except bacterial endospores. J Dent. The suspensions of Rutala WA, Weber DJ.
