What is the minimum recommended temperature for sterilization in an autoclave?

The minimum recommended temperature for sterilization in an autoclave is 250°F (121°C). At this temperature, steam under pressure effectively eliminates all forms of microbial life, including spores, which are resistant to other forms of disinfection. The combination of high temperature and pressure accelerates the penetration of steam into the materials being sterilized, ensuring thorough sterilization in a relatively short amount of time, typically around 15-30 minutes depending on the load and specific autoclave settings.

In dental settings, achieving this temperature is critical for ensuring that instruments and materials are free from pathogens that could lead to infections. Maintaining the proper temperature and time is vital to ensure that sterilization is complete, making 250°F (121°C) the standard guideline for autoclave sterilization practices.
