Which orientation is associated with the Anterior PA x-ray position?

• A. Vertical
• B. Horizontal
• C. Oblique
• D. Diagonal

Answer: (A)

An anterior periapical view is taken with the film in a vertical (portrait) orientation. This setup lines up with the long axis of the front teeth, letting you capture the full length of the incisors and canines, including the tooth apex and surrounding structures, with minimal distortion. Horizontal orientation is used when imaging across the arch for posterior teeth, while oblique or diagonal orientations aren’t standard for this anterior view. So the vertical arrangement best fits the anatomy and goal of an anterior PA radiograph.
