Which two methods are recognized as proper sterilization techniques for handpieces?

The chosen answer highlights steam and chemical vapor sterilization as recognized proper techniques for sterilizing dental handpieces.

Steam sterilization, often achieved using an autoclave, is a widely accepted method because it effectively penetrates the intricate design of handpieces, reaching all surfaces and components. This process utilizes high-pressure saturated steam to kill microorganisms, including bacteria, viruses, and spores, making it a reliable method for the dental environment.

Chemical vapor sterilization employs a mixture of chemicals, which are heated to produce a vapor that circulates within a sealed chamber. This method is advantageous for materials sensitive to moisture or that cannot withstand high levels of steam. As with steam sterilization, chemical vapor also effectively annihilates a broad spectrum of pathogens.

Both methods are validated approaches in the dental field, ensuring the tools are free from contamination and safe for patient use. This is crucial for infection control, given the high standards required in dental practices. The effectiveness of these methods in reaching all necessary surfaces within handpieces reinforces their recognition as reliable sterilization techniques.
