ABSTRACT: The following study was carried out to assess the effectiveness of four disinfectant solutions (Sodium hypochlorite 1%, chlorhexidine gluconate 2%, 100% vinegar and sodium perborate 3.8%) in making acrylic resin specimens free of locally prevalent strains of three different micro-organisms. The organisms tested were Staphylococcus aureus, Escherichia coli and Candida albicans. The study was conducted following a request by the Prosthodontics Department in the college, as part of the annual quality appraisal. One hundred and fifty samples of the standardized acrylic resin specimens were participated in the study, of which, 30 specimens were run as controls. It was concluded that 1% sodium hypochlorite, 2% chlorhexidine, 100% vinegar and 3.8% sodium perborate are all useful as disinfectants of acrylic resin, to make it free from local strains of Staphylococcus aureus, Escherichia coli and Candida albicans.
