Question 7

Which tool has dramatically improved the efficiency and effectiveness of endodontics?

Accepted Answer

The operating microscope has dramatically improved the efficiency and effectiveness of endodontics by providing magnification and illumination, allowing for better diagnosis and treatment of root canals.

Question 8

In which proportion of cases is root canal therapy successful?

Accepted Answer

Root canal therapy has a high success rate, with studies showing that it is successful in about 95% of cases. This procedure effectively removes infection from the tooth, allowing it to be saved and used normally after treatment.

Question 9

Which component of an endodontic examination is subjective?

Accepted Answer

Pain intensity is subjective as it is based on the patient's description and perception of their pain. The other components of an endodontic examination (medical history, dental history, radiographs) are more objective in nature.

Question 10

In which surgical procedure is the tip of a tooth root removed?

Accepted Answer

Apicoectomy, also known as root-end resection, involves the removal of the tip of a tooth root and infected tissue surrounding it. This is typically done when a previous root canal treatment has failed or if there is an infection in the bone surrounding the root. Retrograde restoration involves placing a filling material at the tip of the root after it has been removed, while root amputation and hemisection involve removal of a portion of the root or tooth, respectively.

Question 11

Gutta-percha points are made of:

Accepted Answer

Gutta-percha points are a type of dental material that is made of rubber. This material is used in endodontic procedures to fill and seal the root canal after the pulp has been removed. Gutta-percha points are known for their flexibility, which helps to ensure a tight seal when filling the root canal. They are also biocompatible, meaning they are unlikely to cause an allergic or inflammatory reaction in the patient.

Question 16

Which diagnosis corresponds to a patient who experiences pain with thermal stimuli?

Accepted Answer

Reversible pulpitis is characterized by pain in response to thermal stimuli, which typically resolves once the stimulus is removed.

Question 17

The answer of A _________ endodontic ruler is used to...

Question 18
