Single-use prophy angles must be ______.

Single-use prophy angles must be disposed of after the first use to ensure patient safety and prevent cross-contamination. These devices are designed for one-time use only, primarily to minimize the risk of transmitting infectious agents between patients. The materials used in single-use prophy angles are not intended to withstand cleaning or sterilization processes effectively, which may lead to the retention of bacteria or other pathogens.

Using a fresh, sterile prophy angle for each patient is an integral part of infection control protocols in dental practices. This practice not only adheres to OSHA and CDC guidelines but also fosters a standard of care that prioritizes patient health and safety. It is crucial for dental professionals to maintain strict adherence to these protocols to ensure a safe clinical environment.
