Question: 1 / 400

What type of radiograph would be exposed through the course of root canal therapy?

Bitewing

Periapical

A Bitewing radiograph is used to examine the crown of the teeth and the interproximal spaces. This type of radiograph would not be exposed during root canal therapy, as it focuses on different areas of the tooth.

A Panoramic radiograph captures an image of the entire mouth and would not provide the detailed views necessary for root canal therapy.

An Occlusal radiograph is used to view the development and position of the teeth within the jaw and would not be necessary during root canal therapy.

The correct answer, Periapical, refers to a specific type of radiograph that shows the entire tooth, including the root and surrounding structures. It is commonly used in root canal therapy to assess the condition of the tooth and root during the procedure.
