The sterilization of instruments typically involves the following steps:
1. Pre-cleaning: Removal of visible soil and organic material. This can be done manually or using ultrasonic cleaners. 2. Disinfection: Instruments are soaked in a disinfectant solution to kill most microorganisms. 3. Sterilization: Instruments are subjected to high-temperature steam in an autoclave, or to chemical sterilants, depending on the material and usage.
