Abstract

Abstract -The aim of the present study was to evaluate the effectiveness of different disinfectants on the reduction of two resistant bacteria from the surface of impression materials. Impressions were made of a sterile metal model of the edentulous maxillary arch which had been contaminated with Staphylococcus aureus and Enterecoccus faecalis. The impressions were cultured before and after disinfection with 0.525 % sodium hypochlorite, Gludex and Mikrozid spray disinfectant. For each of the three impression materials and the two microorganisms, spray disinfectant was found to be less effective than either sodium hypochlorite or Gludex.

KEY WORDS: Impression material; microbiology; disinfection; disinfectants
