ABSTRACT

Background: Many studies have evaluated the effect of various disinfectants and methods of disinfecting impression materials, but the results of those studies varied widely. The present study aimed at assessing the disinfection effect of Deconex and 0.525% NaOCl on condensational silicone impression material. Materials & Methods: The present study was conducted 20 samples of heavy body impression material. 10 were disinfected with 0.525% NaOCl and other 10 with deconex. All were incubated on Tryptic soy broth (TSB) for 24–48 h; after which the bacterial growth was examined. Results: In group I samples, 0.525% NaOCl disinfectant was used and in group II, deconax disinfectant was used. 0.525% NaOCl at 5 minutes showed 98.11% clearance of Staphyloccus aureus and 93.27% of candida albican and 100% at 10 minutes. Deconax at 5 minutes showed 97.14% clearance of Staphyloccus aureus and 93.27% of candida albican and 100% at 10 minutes. The difference was non- significant (P- 0.1). Conclusion: Author concluded that 0.525% NaOCl and deconex could effectively disinfect condensational silicone contaminated by the tested microorganisms.It is recommended for disinfecting of condensational silicone impression materials by spraying method
