What should be used to prevent a patient from swallowing the clamp during a procedure?

Using a floss ligature on the buccal side of the clamp's bow is an effective method to prevent a patient from swallowing the clamp during dental procedures. This technique involves securely tying the floss around the clamp, creating a safety tether that ensures the clamp remains in the treatment area and minimizes the risk of accidental ingestion. The ligature provides an additional point of control that enhances patient safety, especially in cases where the clamp may become dislodged.

Rubber dam isolation is an important tool for maintaining a clean working field and protecting the patient from debris, but it is primarily used for moisture control and does not specifically address the risk of swallowing a clamp. Gauze pack can be used to catch any debris or provide cushioning, but it does not actively prevent a high-risk object like a clamp from being swallowed. A dental bib is designed to protect the patient's clothing during a procedure, but it serves no functional purpose in preventing the swallowing of items used in the dental field.

The use of the floss ligature stands out as a direct and practical measure to enhance patient safety in this scenario.
