**Core Concept**
When performing dental procedures, particularly those involving the use of a dental dam, it is crucial to prevent the aspiration of instruments or other materials. The dental floss is strategically applied to the distal bow of a clamp to ensure the clamp does not become dislodged and pose a risk of aspiration.

**Why the Correct Answer is Right**
The dental floss is applied to the distal bow of the clamp to prevent aspiration of the clamp during dental procedures. This is particularly important when working with patients who have a gag reflex or are at risk of aspiration. The floss acts as a tether, securing the clamp in place and preventing it from becoming dislodged and potentially entering the airway. This is a critical safety measure to prevent complications and ensure patient safety.

**Why Each Wrong Option is Incorrect**
**Option A:** The dental floss is not applied to facilitate the removal of the clamp, but rather to prevent it from becoming dislodged in the first place.

**Option C:** The dental floss is not used to anchor the dam as cervically as possible, but rather to secure the clamp.

**Option D:** The dental floss is not used to stabilize the clamp, but rather to prevent it from becoming dislodged and posing a risk of aspiration.

**Clinical Pearl / High-Yield Fact**
When applying a dental dam, it is essential to secure the clamp in place using floss to prevent aspiration. This is a critical safety measure that should not be overlooked.

**✓ Correct Answer: B. To prevent aspiration of clamp**
