What is sterilization?

What is sterilization?

• A. Kills some microbes but not spores
• B. Kills all microbes including spores
• C. Sterilizes without heat
• D. Neutralizes odors

Answer: (B)

Sterilization means destroying all microorganisms, including the most resistant ones like bacterial spores. In practice, this ensures instruments are completely free of viable microbes, which is essential in tattoo and piercing settings to prevent infections. This is different from disinfection, which reduces microbial load but may not kill spores, and from sanitization, which cleans to lower the overall number of microbes. Methods such as autoclaving (steam under pressure) or other validated sterilants are used to achieve this complete elimination. The statement that sterilization kills all microbes including spores is the precise definition. The other options describe partial killing, odor neutralization, or imply heatless methods as the sole route, which do not capture the full, definitive goal of sterilization.
