The Anterior PA x-ray position is oriented in which direction?

The Anterior PA x-ray position is oriented in which direction?

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

Answer: (A)

Vertical orientation is used for an anterior periapical radiograph. Positioning the film with its long axis up and down aligns with the long axis of the anterior teeth, allowing the entire length of the teeth and their apical areas to be captured clearly with minimal distortion. This orientation provides better visualization of root outlines and surrounding bone in the front of the mouth. Horizontal orientation would not efficiently cover the slender anterior region and can distort or truncate the image, while diagonal or circular orientations are not standard for this view.
