• A. Hemisection
• B. Root amputation
• C. Extraction
• D. Apicoectomy

Answer: (B)

Root amputation is the surgical removal of one or more roots of a multirooted tooth while the crown and the remaining roots are preserved. This lets you save the tooth when only one root is compromised, leaving the crown and the other roots functional. After this procedure, the remaining root(s) are usually retreated endodontically and restored for proper function. Hemisection involves removing part of the crown along with a root, so the crown isn’t kept intact. An apicoectomy removes only the apex of a root, not an entire root, and extraction would remove the whole tooth. So preserving the crown while removing a root aligns with root amputation.
