Which of the following is an example of an extraoral radiograph?

An extraoral radiograph is a type of dental X-ray that captures images from outside the mouth. The purpose is to get a broader view of the jaw and facial structures, which is essential for certain diagnostic purposes.

The PA Skull radiograph is categorized as an extraoral radiograph because it involves taking images of the skull and facial structures from outside the oral cavity. This type of imaging helps in assessing conditions that may not be visible with intraoral radiographs, which are taken within the mouth.

In contrast, bitewing radiographs, periapical radiographs, and horizontal bitewings are all intraoral radiographs. These types focus on capturing specific areas within the mouth, such as the crowns of the teeth and the surrounding periodontal structures.
