What does root amputation entail?

1. Removing a single root of a tooth

2. Extracting the entire tooth

3. Filling a canal with material

4. Scalping the top of a tooth

The correct answer is: Removing a single root of a tooth

Root amputation specifically refers to the surgical procedure that involves the removal of a single root from a multi-rooted tooth. This technique is typically employed in cases where one root of a tooth is diseased or infected, while the remaining roots may still be healthy and capable of supporting the tooth. The primary goal of root amputation is to preserve the tooth as much as possible while addressing localized issues, thus maintaining the function and aesthetics of the dental arch. In contrast, extracting the entire tooth completely removes all roots and the crown, which is not the intent of root amputation. Filling a canal with material pertains to endodontic treatment and is not related to the surgical removal of a root. Scalping the top of a tooth typically refers to altering the height of a tooth or crown rather than dealing with root structure. This further clarifies the precision and purpose of root amputation in dental procedures.
