Which term refers to a procedure where the nerve of the tooth is removed and replaced with a filling material?

• A. Root Canal
• B. Space Maintainer
• C. Sterilization
• D. Tartar

Answer: (A)

The idea being tested is endodontic therapy, where the tooth’s nerve tissue is removed and the space is sealed with filling material to save the tooth. In a root canal procedure, the pulp inside the crown and root canals is taken out, the canals are cleaned, shaped, and disinfected, and then they are filled with a material such as gutta-percha to seal the space. This prevents bacterial reinfection and allows the tooth to function normally, often with a crown added afterward for protection. The other terms don’t describe this process: a space maintainer is a pediatric appliance to hold space after a tooth loss; sterilization refers to making instruments or areas free of microbes; tartar is hardened plaque on teeth.
