Which of the following is a common method of sterilization in dental practices?

Autoclaving is recognized as a common and effective method of sterilization in dental practices. This process uses steam under pressure to reach high temperatures, which is capable of killing a wide range of pathogens, including bacteria, viruses, and spores that may be present on dental instruments. The autoclave operates at temperatures typically around 121°C (250°F) for a specified duration, ensuring thorough sterilization throughout the instruments' surfaces.

In the context of infection control in dental settings, it is essential to utilize methods that guarantee the complete eradication of infectious agents. Autoclaving is preferred because it provides consistent and reliable results compared to other methods. The combination of heat and pressure during the cycle not only makes it effective but also allows it to be validated and monitored through biological indicators.

Boiling water, while sometimes thought to kill bacteria, is not effective at sterilizing instruments as it does not reach the necessary temperatures to destroy spores. Ultrasonic cleaning, on the other hand, is used for cleaning but does not achieve sterilization; it removes debris using sound waves but does not kill all microorganisms. Chemical wiping may assist in disinfection, but it does not guarantee sterilization as it relies on chemical agents that may not penetrate all surfaces effectively or act on
