Which term describes the process that destroys all forms of microbial life on an instrument?

• A. Sanitation
• B. Disinfection
• C. Sterilization
• D. Pasteurization

Answer: (C)

Destruction of all microbes on an instrument is sterilization. This level of decontamination aims to eliminate every form of microbial life, including resistant bacterial spores, so nothing viable remains. Sanitation reduces dirt and microbes to a safe level but doesn’t guarantee total kill. Disinfection lowers the number of pathogenic organisms on surfaces but may not inactivate spores or the most resistant microbes. Pasteurization uses heat to significantly reduce microbial load, mainly for foods and liquids, and isn’t intended to achieve complete sterility on tools. In practice, sterilization is achieved through methods like steam under pressure, dry heat, chemical sterilants, or irradiation, all designed to ensure that no living microorganisms survive.
