Which of the following is an indication for frontal projection teleradiography?

• A. hypodontia
• B. incisive-canine crowding
• C. sagittal malocclusions
• D. vertical malocclusions

Answer: (D)

Frontal projection teleradiography is most useful when you need to evaluate symmetry and vertical relationships between the two sides of the face and jaws. It helps reveal occlusal canting, differences in vertical height between the left and right sides, and any midline shifts that aren’t as readily seen on a lateral view. Vertical malocclusions involve discrepancies in vertical dimension and can produce unequal jaw heights or canting of the occlusal plane. A frontal projection highlights these vertical imbalances between the sides, making it the most appropriate imaging choice when you’re assessing vertical discrepancies in an orthodontic workup. In contrast, hypodontia is primarily a dental-arch issue best assessed with intraoral examination and panoramic or periapical imaging; crowding is typically evaluated with dental casts and panoramic radiographs; sagittal malocclusions are best evaluated with a lateral cephalogram to assess anteroposterior relationships.
