Cephalometric projections show the entire side of the head and are used to assess a person’s teeth by their profile to determine the best orthodontic treatment.

• A. Show the entire side of the head. Used to look at a person's teeth by their profile and determine the best type of orthodontic treatment
• B. Intraoral radiographs that capture the crowns
• C. Panoramic images of the jaws
• D. Cephalometric projections show the entire side of the head and are used to assess profile for orthodontic planning

Answer: (D)

Cephalometric radiographs provide a side view of the head, allowing you to evaluate the facial profile and the skeletal and dental relationships of the jaws. This profile view lets you measure how far forward or backward the maxilla and mandible sit relative to the cranial base, assess incisor inclination, and monitor growth and changes over time. Because orthodontic treatment hinges on aligning teeth within the skeletal framework to achieve a balanced facial profile, these images are essential for planning the most appropriate approach, whether braces alone, growth modification, or extractions. Intraoral radiographs focus on individual teeth crowns and roots, and panoramic images show the jaws and teeth without the detailed lateral skeletal relationships, so they don’t provide the profile context needed for this planning.
