What is the function of chelators in root canal treatment?

1. To mix with anesthetics

2. To harden dental materials

3. To soften tissue

4. To bond materials together

The correct answer is: To soften tissue

Chelators play a crucial role in root canal treatment by softening tissue. Specifically, they are employed to dissolve and remove inorganic materials, such as calcium deposits, from the root canal system. This action helps in effectively cleaning the canal and facilitating the removal of necrotic tissue and debris. By softening the tissue, chelators make it easier to achieve a thorough debridement, which is essential for successful endodontic therapy. This cleaning is vital, as it prepares the canal for proper sealing and prevents further infection. The other options do not accurately reflect the primary role of chelators in this dental procedure. Chelators are not used to mix with anesthetics, harden materials, or bond materials together; rather, their primary function focuses on tissue softening to promote effective cleaning during root canal treatments.
