The correct autoclave parameters for sterilization involve using a temperature of 134°C, a pressure of 2.2 bar, and a time of 3 minutes. This combination is widely accepted as effective for sterilizing dental instruments and materials.

Autoclaving at 134°C is optimal because this temperature effectively kills a broad range of microorganisms, including spores that are resistant to lower temperatures. The pressure of 2.2 bar is necessary to ensure that steam can penetrate the materials being sterilized and to maintain the temperature required for sterilization. The time of 3 minutes at this temperature and pressure is sufficient to ensure that the instruments are thoroughly sterilized, taking into account the need for steam to circulate around items and penetrate packaging.

This method is important to ensure safety and efficacy in a dental setting, where the risk of infection must be minimized. Adhering to these specific parameters helps dental professionals maintain a sterile environment and protect patient health.
