The dental specialty that focuses on tooth pulp and root canal systems is called __________.

• A. Orthodontics
• B. Endodontics
• C. Prosthodontics
• D. Periodontics

Answer: (B)

This question tests your understanding of dental specialties by identifying which one focuses on the inside of the tooth. The pulp is the soft tissue inside a tooth that contains nerves and blood vessels, and the root canal system is the network of canals within the roots that houses that pulp. Endodontics specializes in diagnosing and treating problems related to the dental pulp and root canals, including root canal therapy to remove infected or inflamed pulp, clean and shape the canal spaces, and seal them to save the tooth.

This is distinct from other specialties: orthodontics deals with aligning teeth and jaws, prosthodontics focuses on replacing missing teeth with crowns, bridges, dentures, or implants, and periodontics concentrates on the gums and supporting structures around teeth, such as treating gum disease and bone loss. Therefore, the dental specialty that focuses on tooth pulp and root canal systems is Endodontics.
