Sterilization is the process that

• A. destroys most but not all microbes
• B. destroys none
• C. only disinfects surfaces
• D. completely destroys microbial life including spores

Answer: (D)

Sterilization means completely destroying all microbial life, including hardy spores, on an object. This is the highest level of decontamination and goes beyond disinfection, which only reduces the number of microbes and may not eradicate spores. Antisepsis targets living tissue to prevent infection, not inanimate objects. Methods like autoclaving (steam under pressure), approved high-level chemical sterilants, dry heat, and irradiation achieve true sterilization. In esthetics, this is why tools that contact sterile areas are autoclaved or used once and disposed of when necessary, ensuring no viable organisms remain.
