What type of sterilization method uses steam under pressure?

The method that utilizes steam under pressure for sterilization is autoclaving. This process involves the use of a specialized device known as an autoclave, which generates steam and increases the pressure within a closed chamber. The combination of high temperature and pressure effectively destroys bacteria, viruses, fungi, and spores, ensuring that instruments and materials are sterile and safe for use in dental settings.

Autoclaving is particularly favored in medical and dental environments due to its efficiency and ability to penetrate materials, thus allowing for the thorough sterilization of a variety of items, including those that are porous or wrapped. The process usually operates at temperatures around 121-134 degrees Celsius for a specified duration, providing a reliable means of sterilization that meets stringent health and safety standards.
