Endodontics focuses on which area?

• A. Alignment or straightening of teeth
• B. Replacement of natural teeth with artificial teeth
• C. Surgery on the teeth, mouth, jaw, and facial bones
• D. Treatment of disease of the pulp, nerves, blood vessels, and roots of the teeth

Answer: (D)

Endodontics deals with the inside of the tooth—the dental pulp and the root canal system. When the pulp becomes inflamed or infected, endodontists treat it to save the tooth by removing diseased tissue, disinfecting the canals, and sealing them. This includes root canal therapy and related procedures that address disease of the pulp, nerves, blood vessels, and roots. Other areas of dentistry cover different goals: straightening teeth is orthodontics, replacing natural teeth with artificial ones is prosthodontics, and surgeries on the teeth, mouth, jaw, and facial bones fall under oral and maxillofacial surgery. So the area described is endodontics, centered on the pulp, nerves, blood vessels, and roots of the teeth.
