OBJECTIVE To evaluate the efficacy of several methods of sterilization and disinfection on two different types of composite finishing and polishing instruments. METHODS The instruments consisted of a proprietary light-cured resin cup impregnated with an abrasive and a silicon dioxide-impregnated rubber cup. Chemical and physical methods included treatment with iodophor, synthetic phenol, glutaraldehyde, microwaving, autoclaving, and chemiclaving. RESULTS Glutaraldehyde (Vital Defense-S) was an effective disinfectant; however, other chemical (cold) disinfectants overall, were not reliable. Autoclaving, chemiclaving, and microwaving all provided to be effective means of sterilization.

UI	MeSH Term	Description	Entries
D007466	Iodophors	Complexes of iodine and non-ionic SURFACE-ACTIVE AGENTS acting as carrier and solubilizing agent for the iodine in water. Iodophors usually enhance bactericidal activity of iodine, reduce vapor pressure and odor, minimize staining, and allow wide dilution with water.

D004202	Disinfectants	Substances used on inanimate objects that destroy harmful microorganisms or inhibit their activity. Disinfectants are classed as complete, destroying SPORES as well as vegetative forms of microorganisms, or incomplete, destroying only vegetative forms of the organisms. They are distinguished from ANTISEPTICS, which are local anti-infective agents used on humans and other animals. (From Hawley's Condensed Chemical Dictionary, 11th ed)	Biocide,Disinfectant,Biocides
