Endodontics saves a tooth that might otherwise require extraction?
- A.
True
- B.
False
Correct Answer
A. TrueExplanation
Endodontics is a branch of dentistry that focuses on treating the inner part of the tooth, known as the pulp. When the pulp becomes infected or damaged, it can lead to severe pain and potentially the loss of the tooth. However, endodontic treatment, such as root canal therapy, aims to remove the infected pulp, clean the root canals, and seal them, thus saving the tooth from extraction. Therefore, the statement that endodontics saves a tooth that might otherwise require extraction is true.Rate this question:

All of the following are radiographic images exposed throughout an endodontic procedure, except?
- A.
Initial radiographic image
- B.
Extraoral radiograph
- C.
Final instrumentation radiograph
- D.
Root canal completion radiograph
Correct Answer
B. Extraoral radiographExplanation
An extraoral radiograph is not typically exposed throughout an endodontic procedure. Endodontic procedures involve the treatment of the pulp and root canals of a tooth, which requires intraoral radiographs to visualize the internal structures of the tooth. Extraoral radiographs, on the other hand, are taken outside of the mouth and are used to visualize larger areas, such as the entire jaw or skull. Therefore, an extraoral radiograph is not necessary during an endodontic procedure.Rate this question:
