Dental Assistant Practice Exam

What kind of treatment is typically required for irreversible pulpitis?

1. Regular cleaning

2. Fillings

3. Root canal therapy (endodontic therapy)

4. Antibiotics only

The correct answer is: Root canal therapy (endodontic therapy)

Root canal therapy, also known as endodontic therapy, is required for irreversible pulpitis because this condition signifies that the pulp of the tooth has become inflamed and infected to the extent that it cannot heal on its own. In irreversible pulpitis, the nerve and pulp inside the tooth are permanently damaged, often resulting from extensive decay, trauma, or a deep cavity. During a root canal procedure, the dentist will remove the infected pulp tissue, clean the inside of the tooth, and seal it to prevent further infection. This treatment aims to relieve pain and save the tooth from extraction. Regular cleanings, fillings, or antibiotics alone are insufficient for this condition, as they do not address the underlying infection or damage within the pulp.
