Which of the following is true regarding wearing two pairs of gloves?

Wearing two pairs of gloves can indeed provide an extra layer of protection. The primary purpose of gloves in dental practice is to protect both the patient and the healthcare provider from the transmission of pathogens. When a healthcare provider wears two pairs of gloves, it can enhance their barrier against contamination, particularly in situations where there is a higher risk of exposure to blood or other potentially infectious materials. This additional layer can help minimize the chance of breaches that could occur with a single pair, thereby improving safety for both parties.

Using two pairs of gloves can also be beneficial during procedures involving sharp instruments or when the risk of glove puncture is higher. In such cases, if the outer glove does become compromised, the inner glove can still offer protection. However, it's important to note that while double-gloving can enhance safety, it does not replace the need for proper hand hygiene and adherence to infection control protocols.

The other options relate to glove use in ways that do not accurately represent the implications of double-gloving. For instance, double-gloving does not enhance sensitivity; in fact, it may actually decrease tactile feedback. Similarly, it does not reduce the need for handwashing; proper handwashing remains essential before and after any glove use. Finally, the use of
