Abstract

The purpose of this study was to evaluate the efficacy of disinfection method using a flow water system with electrolytic products of sodium chloride (BK) on alginate impressions and subsequent atone casts contaminated with Candida albicans and blood. The dimensional changes and surface roughness of alginate impression on BK water were evaluated.<BR>Each alginate impression from a model of maxillary dental arch was inoculated with each<I>Candida albicans</I>cell suspension at a density of 1.5 × 10<SUP>7</SUP> cell/ml and sheep blood. The impression was disinfected with BK flow water and residual microorganisms were harvested, cultured, and counted. The washing disinfection with BK flow water removed most<I>Candida albicans</I>. Thus, after the washing disinfection of impressions with the flow BK water, the subsequent stone casts were disinfected again with flow water and then residual microorganisms were counted. The washing disinfection of alginate impression for 30 seconds and subsequent stone casts for 15 seconds with flow BK water removed all<I>Candida albicans</I>inoculated. This infectant technique using flow BK water is effective and simple.
