Sterilization is the best method to counter the threats of microorganisms. The purpose of sterilization in the field of health care is to prevent the spread of infectious diseases. In dentistry, it primarily relates to processing reusable instruments to prevent cross-infection. The aim of this study was to investigate the efficacy of 4 methods of sterilizing endodontic instruments: Autoclaving, carbon dioxide laser sterilization, chemical sterilization (with glutaraldehyde) and glass-bead sterilization. The endodontic file was sterilized by 4 different methods after contaminating it with bacillus stearothermophillus and then checked for sterility by incubating after putting it in test tubes containing thioglycollate medium. The study showed that the files sterilized by autoclave and lasers were completely sterile. Those sterilized by glass bead were 90% sterile and those with glutaraldehyde were 80% sterile. The study concluded that autoclave or laser could be used as a method of sterilization in clinical practice and in advanced clinics; laser can be used also as a chair side method of sterilization.
