What does a periapical image show?

A periapical image is a type of dental radiograph specifically designed to capture the entire tooth and the surrounding tissues, including both the crown (the visible part of the tooth above the gum line) and the root (the part of the tooth that is embedded in the jawbone) as well as the surrounding alveolar bone, which supports the teeth. This comprehensive view is essential for diagnosing conditions related to the entire tooth structure, including any potential issues in the root area or surrounding bone structures.

The other options suggest incomplete views. One hints at images showing only the crown, which would omit critical root information. Another option focuses on a portion of the tooth and does not encompass the essential structures necessary for a complete dental evaluation. Lastly, an option mentioning only the crown and root bypasses the significance of surrounding tissues, which are integral to understanding the health of the tooth and the surrounding dental structures.
