What is the procedure called for the removal of periodontal packs?

The procedure referred to for the removal of periodontal packs is best described as "removal." This term specifically denotes the action of taking out the periodontal packs that have been placed over surgical sites in the mouth to protect healing tissues or to facilitate oral hygiene.

Understanding the context is important: periodontal packs are often used after surgical procedures to stabilize the area and support healing, and thus, removing them requires a careful and specific approach. "Removal" accurately captures the essence of what is being done, which is to take out the existing material that has served its purpose.

While debridement relates to the cleaning of a wound or the removal of debris in dental practice, it doesn't specifically pertain to the act of taking out packs. Scaling is focused on cleaning the teeth and removing plaque and calculus, while extraction refers to the removal of a tooth. Each of these procedures has its own specific context and application, making "removal" the most appropriate answer when it concerns the act of taking out periodontal packs.
