After mixing permanent cement, what should be done to the spatula and glass slab?

1. Let them air dry

2. Cleaned immediately with wet gauze and disinfected

3. Washed with soap and water

4. Disposed of as biohazard waste

The correct answer is: Cleaned immediately with wet gauze and disinfected

When mixing permanent cement, it is critical to clean the spatula and glass slab immediately with wet gauze and then disinfect them. This approach ensures that any residual cement is effectively removed before it has a chance to harden, which can make cleaning more difficult and may leave behind residues that can affect future procedures. By using wet gauze, you can easily wipe away the mixture while it is still malleable, preventing it from solidifying on the tools. Additionally, disinfecting the tools is crucial in a dental setting to minimize the risk of cross-contamination and to maintain a sterile environment. Permanent cement can harbor bacteria if not properly cleaned and disinfected, leading to potential infections or complications in subsequent procedures. This methodical cleaning process is an essential practice in infection control, keeping both the dental instruments and work area safe for patients. Other choices, while they may seem practical, do not prioritize immediate cleaning or proper disinfection, which are vital to maintaining hygiene standards in a dental practice.
